Before you buy a new fuse, just apply some pressure on the fuse with a small screw driver, it pushes in and works again. It worked for me at least. If doesnt help, just remove the fuse and connect 2 points without fuse, it will work just fine.
It is possible to run without fuse but I always say that safety element is there for a reason. Please consider adding a fuse.
Pushing down the fuse fixed my issue as well. Thanks for sharing! Although I have a feeling it is not a long term fix but that’s a problem for another day.
Interesting fix with the pressure.. if not much to ask could you update your comment if or when it dies again. This would be very interesting experiment..
@@letsfixitgarage just an update, still works well. We also use 1 toothbrush for 2 people, meaning it works at least for 8-10 minutes per day. Will let you know when/if it does
Amazing! it worked!! thought it was a faulty battery! just pushed it down too. It worked right away (it's really really tiny), Such a shame those companies are providing such poor design, second that's dying for me. Do you know where to find a remplacement fuse?) Thanks a lot
Thank goodness for this channel! Saved me $200 buying a new toothbrush. Confirming, as others have said, that you don't necessarily need to replace the fuse. You can just push on the fuse with a screw driver while pushing the power button and it will come back to life. Thank you so much for posting this video!!
Super. It works like a charm. This is the original fuse: MF-PSML300/6-2, PPTC SMD POLYMER PTC 3.0A/6.
So here’s the situation: I’m in Brazil and this is a really expensive gadget to buy. If it weren’t for your video AND the comments here on pressing on the PP fuse, I’d really have to replace it with a cheaper option. Thanks so much, my friend!!!!!
This video just saved me 200$, pried it open and applied some light pressure on the pp fuse and it started to work.
If you’re going to be applying pressure to the fuse, remember to have the brush turned ON while doing so. This is what made my brush work again!
How is this repair method holding? I always suggest replacing the fuse but I see big portion of comments stating that this method works, not much on how long it holds..
@@letsfixitgarage yes it would make more sense to replace The fuse, but i figured that if The brush works then why worry about it? I did this a couple of weeks ago and The brush still works
You're a king, @sebastianmller4544. I pressed on the fuse with no luck, but then, per your advice, turned on the toothbrush, while applying pressure, and it came back to life!
@@Timmones thank you bro, you’re welcome 😄
@@sebastianmller4544 Thanks a lot!
Hi, that's saved my Oral B Genius X 20000N worthy of 140 € and 4-years old! I just short circuited
I'm from Russia, for some reason we have such a massive breakdown.
Thanks to you, I have learned how to eliminate it.
I divide it easier, instead of a fuse, a drop of solder.
I think it's a very common break down all over the world.. and sadly with a very easy fix.. good luck and thanks for feedback.
Hi, thank you so much for this video. Can you tell me where can I get these fuses, and is it possible to glue the fuse with super glue or something? Sorry, I don't know
Look at the Description. No, you can‘t glue it.
Absolutely EPIC! had this problem last night, similar that I thought it would be the battery. Popped it open, tried to press the fuse but it wouldnt work. Pressed it on and then pressed the fuse down and now its back to its original self. Thanks a ton for the video
little push from the side of the fuse with a small screw driver fixed my issue as well. . If not for your video I wouldn't have known what the fuse and where it is placed. Thank you so much for sharing. I had this problem in two toothbrushes. Both are working now. Thank you again for saving a lot of money.
Thank you to the people who suggested pressing on the fuse because it worked so well I actually scared me! I’m now going to try the same thing on my daughter’s toothbrush Thank you Let’s Fix It Garage for showing so clearly how to open up the toothbrush casing
How is this repair method holding? I always suggest replacing the fuse but I see big portion of comments stating that this method works, not much on how long it lasts..

Thank you very much Sir for this video you have uploaded, its very helpful and practically applicable to my Oral B Genius X toothbrush. I've only used my unit for just a year when i've suddenly experienced this malfunction in my unit, i bought it brand new and yet i experienced this unlikely trouble but thank God, your here to save my day and because you've uploaded a video like this - i'd been saved to pay expensive repairs from any technicians.
It's unbelievable how much information we have freely accessible in these days ;) but it's nothing if there is no will to use it. Glad you used it, Good luck and keep on learning!
@@letsfixitgarage my tooth brush just turns off after like 10seconds how can I fix it or if you can fix it and I pay you
@sebgehtola7828 Repair should be the same, exchange of the fuse. If you are from europe you can write me letsfixitgarage@gmail.com
Hi, thank you so much for this video. Can you tell me where can I get these fuses, and is it possible to glue the fuse with super glue or something? Sorry, I don't know
Thank you for sharing this information. I have a feeling this is a common issue for all these similar models. My first Genius x 10000 died the same way but it was under warranty so they gave me a replacement. Now less than a year later the replacement failed the same way. I was able to revive my toothbrush with your video so thanks again.
I can feel with you. I bought more than 2 years ago a double package with one black and one white version of this toothbrush. My black I changed in warranty already 2 times. Always the same problem. The white one was also not working and I get new one. But yesterday the same problem. That means in sum in 2 years 4 toothbrushes was broken. This is really a bad joke for such expensive version.
Same here. I've replaced 4 under warranty. All failing within a year. Surprise oral b doesn't fix this if it's getting such a high failure rate!
Thanks! My toothbrush was replaced 3 times during 1.5 years . The warranty lasted for 2 years and 1 month after it just stopped working again. I have looked on youtube for some adviced and found this one. As I have no experience with electronics I just used a screwdriver to press on the fuse and it just magically started to work. Now lets see how much it will last.
I'm really surprised with this pressure fix. Really indicates a fuse manufacturing problem... If not much to ask let us know if it holds. I believe had one commenter that fuse failed after few weeks and one that holder permanently (or he didn't reply when it failed) ;)
Me too! We should sue Braun!
it helps me too))) just pushed on fuse by screwdriver and it started to work.
Welp! Here I am. Same problem as everybody else. Watched your video, ordered the fuses and then I started to read all of the comments. I tried the pressure thing on the fuse and that didn't work and then I kept reading. I too heated up the fuse a little bit here and there just for the heck of it. Once I let it cool down I tested it and it works great again. I know you have responded that it probably isn't a good fix but I figured what the heck. We are going to run a test. Today is December 19th 2022. I will return here and comment when or if it goes bad again before I mess with a new fuse.
Thanks for the video
Thanks for your comment. Did you heat it up with hot air or soldering iron? Do update us on your findings! it's unbelievable that this defect occures in the first place...
@@letsfixitgarage Like I said. I did order new fuses but when went to take old fuse out I was like..... my tip isn't that small! I read someone elses comment and tried it. I just put my oversized tip on the fuse a couple times in a couple different places.
Still goin
I also fixed my Genius-X by heating up the fuse with a soldering iron. I assume the fuse isn't broken at all. It is more likely a bad soldering connection which breaks at some point due to the vibration. By heating up the fuse the connection gets "refreshed". In case it happens again I will just remove the fuse and short circuit the thing.
Difficult to say I tried to resolder some of them but no luck. That's why I replace all the fuses when I repair these brushes. I'm really confused that someone succeeds in repairing them by pressing or heating up. Still don't understand why these fuses fail in the first place...
Thanks! Just heating the fuse on both sides was enough to get the voltage to 4 on both sides of the fuse. The toothbrush works again 👍
Electronics and heating usually doesnt work together :) glad it's working for you, but I would suggest getting a replacement fuse for the near future ;)
Thank you I did all of what you mentioned except as other users have mentions I applied pressure to the fuse box named' pp' hard enough until the brush came back to life, saved me £80
Gald it helped! Do let us know if it will hold or will it fail after some time.. thanks!
Thanks!! I was so mad that it stopped working 2 months after the end of warranty... Found your video and just had to press the fuse!
Hi Let it fix garage. This video was very helpful. I‘m not the expert to solder. The greatest challenge was to find someone to solder the fuse.
The electritian will just solder it out and just want to bridge it. I hope it will be alright.
Well it will work, but if there will be some problems in future with motor, more things can brake without a fuse..
Thanks a lot, I desoldered the fuse and instead short-circuited the two pads and now it's working again 😁. As you point out in some comments adding a new fuse is better but I guess the risks involved are fairly low
Thanks for a good word and for reading the comments. Yes it works, as for risks low probability burned motherboard.. very very very low probability burned toothbrush or even bathroom while you sleep. Then fire department investigates that the culprit is Braun toothbrush, news catches the story, Braun finds this comment and sues you for millions because you damaged their name.. well you get the Idea and my Imagination :D moral of the story is always use protection and even better: a good one, not like Braun ;) just joking ;)
@@letsfixitgarage wauw your imagination escalated to a horror scenario really quickly! I had actually been thinking about burning. My thought was that it only seems power to the motor etc while I am actually using the toothbrush. No power goes to the motor when I'm not using it. The toothbrush is right under my nose when I'm using it. So I should smell any problems rather quickly.
That fuse is really tiny and I doubt I have the skills to solder a new one on.
Yes you are right this part should be affected only while using. But you shouldn't underestimate corporate lawyers Imagination when they are bored ;)
I tried the short circuit thing too but It didn’t work :( Have you reset the card?
@LetsFixItGarage Massive thank you for posting!! This was incredibly helpful ❤
Thank you so much ☺️ I just pressed the fuse with a screwdriver, and everything thing was OK again 😁
Followed the procedure, pressed down on the fuse and it all works fine! Thank you very much!
Pressing on the fuse worked for me! We'll see how long it lasts... Thank you for your video!
Glad it helped, let us know if it will fails but I saw some comments that stated that this fixed the brush permanently for them.. although I would not trust that kind of crushed fuse to perform its function..
@@letsfixitgarage Sorry, I never noticed that you responded here. I wouldn't say the fuse is crushed. I think all I did is just made the soldered connection stronger by pushing it back down. I would guess that the vibration of this toothbrush has been slowly separating it over 3 years of use.
...I think.
Well if there is a micro crack in solder point it needs to be resoldered. And only resoldering never worked in my case. That's why I suspect that fuse itself is damaged and if you push on the solder points it would regain the contact only for that time. When you use the brush there is a lot of vibrations that would break it again.. don't get me wrong I'm glad that a lot of people getting second life for their brushes but if the motor would short (quite implausible) I would not trust that kind of fuse to do its job. Just my 5 cents :) and thanks for your feedback!
Hi, thank you so much for this video. Can you tell me where can I get these fuses, and is it possible to glue the fuse with super glue or something? Sorry, I don't know
Your Video is awesome! Exactly the Problem i was having and additional info in comments (pressing down the fuse and resetting the microcontroller helped lots). I now have a working toothbrush again for 0€. Thanks all!!!
Glad it helped and thanks for sharing you experience!
How to reset microcontroller?
Thank you sir you saved me. I just use a screwdriver to put some pressure on the fuse and it is working again!! 🤞🤞🤞
Thank you for a good word and your donation! First time from Japan :) glad it helped, but from my experience pressure on electronic component is not a permanent solution from vibrations it can get loose again.. I would look for a shop where I could bring already disassembled brush and ask for a fuse exchange.. shouldn't cost much..
Thanks, just fixed my Genius 20,000, instead of fuse I placed one thread of multithread wire and sorted the fuse. (in any case, I bought the new io10 🙂)
It worked for me too ❤ Thanks for video 💪
Thank you very much for the video. That was very helpful !!!
Glad it was helpful, Good luck!
Thanks for the video! Managed to get one with leds lighting up and 1 sec of motor action working by compressing the PP fuse. After one use, the whole brush died, no action at all.
The microcontroller (TI CC2640) can be reset by grounding pin no. 35. I used a 1k resistor to ground it on the motor ground.
Brush woke up instantly.
Now testing to see whether it works long-term. I suspect that something is failing on the board. This brush has been abused a bit and it has a crack on the body, but no obvious liquid damage is visible.
How is this repair method holding? I always suggest replacing the fuse but I see big portion of comments stating that this method works, not much on how long it holds..
Sorry was replying to a lot of similar comments haven't noticed that this comment is only 24h old :) hope it will hold if you will remember do let us know if this method worked or did you needed to replace the fuse after all..
I'll definetely report. Planned to order the correct Bourns fuse and the motor mosfet whenever i have enough stuff to order somewhere. Probably the brush OS not going to fail then 😂.
Dude! I thougt i fcked up and bricked the thing. Your comment is saved me! Working like a charm now. Thanks a lot!
@@CharlesBronson111 Glad to hear, Happy to be able to help!
Thanks for the video 🙂
Tried the first fix with pressing on the fuse with the tip of my nail. Works so far 👍
How is this repair method holding? I always suggest replacing the fuse but I see big portion of comments stating that this method works, not much on how long it holds..
@@letsfixitgarage I have seen one comment stating a couple of months. But I tried it as a first quick fix. It will hold up as long as it can. Once a fuse has given up, all fixed with the same fuse are short term. So replacing it is the most viable way to go.
Next time it fails, I will get it replaced 🙂
I followed the video and I just had the soldering iron touched the pp element on both ends without removing them. Guess what? It is working again. Thanks for the video!
It's always nice when something get repaired unintentionally:) I would thou nu a fuse and have it at hand as electronic component that comes back to life after heating is usually not in a best state :)
Thank! I just fixed mine! Got repaired twice within the warranty and now I can do it myself.
Good job! Though I doubt that they repaired it in warranty.. probably just replaced it with the new one..
Thanks - following this guide I fixed my toothbrush!
Excellent! thanks for the feedback :)
Thanks a lot for the very informative video ! you are the best !
Thanks for the video. I followed first the one of the comment below , pressing the fuse worked!
good luck if it stops working you know where the problem is ;)
Nice video! Do you know if they changed this style within the newer IO model? I have a genius x which had this issue, I got it fixed under warranty now the same issue happens. For me I might just get the newer model
No haven't had a chance to get my hands on the new one.. I assume a workshop with tools and stronger fuse could bring your old one to life :)
Thank you, the opening works great ;)
Thank you - pressing "pp" worked for me.
Amazing! pressing down reasonably hard with a blunt object on the fuse also fixed mine!
hi, any update if this repair is hoding up?
Had to open the toothbrush again and press harder - that did it! Still working.
Thanks again man.
Saved some money with your video ❤
Helpful video, thanks!
Thanks for the video, I was able to solve the problem just by applying some pressure on the fuse.
Glad it helped, although I would recommend to replace it with a working fuse..
Everyone who bypassed the fuse have there been any issues? Blown up toothbrush, bathroom, house, city? I just bypassed with blob of solder. I dont have the skill or good enough equipment to solder a new fuse so hoping to leave it.
Thanks for the vid got me working again.
That's nightmare scenario :) there is not that much energy in the battery to do that kind off chaos..my gues would be burned toothbrush inside the case doubt that it would escape in to the outside..and if something happens it should happen when you are using it, as it's motor fuse, so you should have plenty of time to react...
Thank you. It's been nearly a week now using every day and did a full charge. All good so far.
Really appreciated your video here. Same symptoms for me, toothbrush might rotate for 2-3 seconds but would stop, then nothing for several minutes or even wait overnight to get any life again. In my case I applied a bit of pressure to the 'PP' fuse to see if there was any physical connection problem and sure enough, this 'fixed' my problem. So I believe I had a cold solder joint. And with the high vibration of these motors you might expect this to happen with some units. I don't have smd tip or tweezers for my soldering station, but I used my smallest tip and added just a small amount of fresh solder to the fuse pads. Seems to be working for me for a couple days so far. Thanks again.
Nice! leave an update after a month or few to know if it was a permanent solution for you.
Any update on your Oral B Genius X? Exactly what you're describing has started happening to mine and i'm considering popping it open.
Did the same. Works for me as well
Fuse is dying. I would replace it but of course you can try the pressure method..
This worked for me for a few months but the problem happened again
Me has ahorrado tener que comprar un cepillo nuevo. Muchas gracias.
Thanks! For me, resoldering the fuse did the trick.
glad to hear it, thanks for feedback :)
thanks for sharing this information.
Thank you for the video! It seems we all have the same issue. I started to follow your tutorial but having trouble removing the top ring. What tool did you use? TIA.
I usually use a flat head screwdriver. But sometimes it is difficult to remove... Heat it up in hot water for few minutes and be careful with screwdriver not to damage rubber seal on the brush housing under the ring..
@@letsfixitgarage thank you very much!
Danke! You saved my vacation!
If only I would get 1 cent for every.... Oh wait that's the case! Just joking 😅 really appreciate your support! Thanks a lot! 👍
Thank you so much for this video. I have one question I have same toothbrush and when I opened it I saw lots of rust soecialy on the motor part. How can I clean them? Thanks!
difficult to say how dirty it is but usually rust on the outside of the motor doesn't affect its performance. just clean any loose rust with a brush, blow it with compressed air and it should be fine. problem is why you have rust inside.. if all seals are in tact it should be dry and rust-free.. look where water is getting in..
@@letsfixitgarage thanks! 💯🙋♂️
Hi, thanks for the video! Me and my Dad both bought toothbrushes at the same time and I’m about to move out and mine broke. 😂 The pressure “fix” worked for me thankfully. Could using this fuse until failure cause any further damage? And how would I know the fuse has failed completely? Would it just not work? Sorry for the questions lol
difficult to say how crushed electronic component will perform :) some commenters said that it was heating up strongly, for some it just stopped working after some time.
Ironically the fancier more expensive models seem to have more issues.
My $20 model from 15 years ago has been working perfectly since I got it
Well more features mean more things can break :) but yes, especially IO series doesn't look to reliable..
Thank you mine is working now
Hello - Thanks very helpful. I have the same symptoms as you say while during diagnosis with multimeter suddenly lights turned off and I am no longer able to turn it on. Do you have idea what could be the reason- is it possible that it is still the same fuse only? I feel like I created some short circuit or so…
It's difficult to diagnose remotely.. the fuse that I explained was responsible only for powering the motor. Toothbrush itself was functioning.. if it went out while diagnosing I can only assume that some component was shorted out with probes.. check battery voltage both fuses and go from there...
Hello, i have the Same Problem...my one was just turning for a few seconds and after open it nothing is work. But where is the seconds fuse? That is the third Genius with a fault and now i haven't warranty any more.
Both fuses are next to each other.
I have Take the other genius fromm my cellar and bridge the 2A fuse. That one ist Wirkung now and i will order the fuse and replace the old one...so one genius ist fixes...but the other genius still death and i can mit find the other fuse...it ist the same fuse? Thank you very much for help.
I think is the SMD with letters E on the top. That one is not broken in my case. So i think i don't will get fix it.
Thanks, I ordered some fuses but they ended up not fitting, but when I tested the old fuse with a multimeter it showed continuity, so I soldered it back on and it's working now, for how long I don't know, but for now it does.
I would sugest to look for smaller fuses as this one will not hold for to loong.. and yes these fuses are very small and requires some tools and skill to resolder..
It stopped working again, I might try to find a new fuse that fits this time
Hello! I just found my Oral B Genius X wouldn’t charge and turn on! I think it is because of the damaged electrode between the battery and the mainboard. Do you have any ideas on how to fix it? Thank you very much!
Difficult to say.. why do you think it is damaged? It's solid piece of metal it should hold fine.. But if it is really broken, then you would need to restore the contacts between battery and board..
Thank you so much!
My brush would run for a second or two, slow down and stop. I found that polyfuse marked PP was dropping about 3 volts in the stopped condition. PP is a Bourns MF-PSML300/6-2 0805 rated 3A. Bypass PP with a multimeter set to DC current, the brush runs and the meter reads 0.5A so my fuse must be faulty. I bridged the fuse with solder and it works now.
Yes saw similar dying fuse behaviour as well. I would replace the fuse with some similar smal fuse.. bridging is ok to test the concept but fuses are there for a reason :)
@@letsfixitgarage Getting hold of a replacement fuse is not easy, neither is soldering it.
I have few links in description for the fuses, they are not OEM but seems to hold ok. And yes it needs some practice with these small components..
@@letsfixitgarage The ones in the description are rather expensive and are not rated 3A ...
Regarding 3A not sure it's needed.. If I remember correctly under load the motor was something in 300ma range.. tested it with these fuses that I had on hand (rated 2A but haven't tested) it worked fine so that's the only experience I have to share :)
Cześć. Mam szczoteczkę oral b pro 2 2500. Po włączeniu jest mały dźwięk. Nic nie świeci, silnik nie kręci. Bateria jest dobra. Jakis pomysł? Proszę o pomoc
I have the same problem with Oral-B Genius X Limited, should I buy the same piece of fuse that I used with the same power or do I need a different power
Sorry don't understand what you mean with power but made some experiments and usualy consumption is 200-600ma so fuse for 1A should be sufficient I usually put 2A fuse.
I’ve tried for an hour to get the top cap off and have cracked it along the way. I’ve tried all sorts to get it off (even heating it). Any recommendations for getting it off?
Sometimes it's very difficult.. for me few methods work but none is 100% safe.. will try to do an update on this toothbrush with some tips in near future..
Hello,
I am trying to find a document/source/information indicating the meaning of colour "main" LED which has turned from white to blue+green (from outside looking, no dismantling) recently and these last couple randomly days into full blue.
I hold a genius 9000 from 3 years now and it behaves like that recently (3months approx). I also observed once I started it, it was stopping by itself despite battery indicator was showing not empty. Furthermore, if you apply too much pressure during brushing, main LED should lights which I didn't observe since a while... I had previous Oral B generation which I do not remember the category.
No sign of battery charging/duration loss/decreasing in power/rotation speed or even noise except when battery goes low charge ( I never wait a full discharge for recharging). Oral are quite noisy compared competitors ;)
From full charge (couple hours upon charging voltage so mainly during night/sleeping [I am changing world region with working area => 110-240Vac], I do not observe any battery life "reduction".
My first query would the battery's spec. I read through few website indication of 1.2V but once opened with elements in place (nothing removed), I measured 3,49Vdc approx. Once board/mechanism removed from holder, my battery looks similar the one on this video, same colour.
Sharing troubleshooting experience just now ; ) . Prior looking that video, I was trying to investigate more and possibly replace the battery, I bought one of 1,2Vdc. There was some rusted moisture near "teeth wheels" behind the motor. It may have affected the board components and produced unexpected behaviour. I didn't succeed (very limited hand welder or too old) to remove the battery for better inspection but after this, I noticed by pressing the starting button, the toothbrush was keeping in operation without interruption as written above. It might happened during welding I "remade" the connection battery to board on better connection than before. At the end, old battery still in place.
However, the 2 leds (blue and green) remain ON during operation phase. I am very curious of the colour designation. I remember at first bought, main LED (from outside looking) was white.
Any suggestion/idea or eve from "Vilnius". Would great, thank you.
Greetings from Vilnius :) there is a lot writen so sorry if not everything will be answered but few things regarding color of the led if I recall correctly it is a Bluetooth enabled device and with app you can change the colour of the lights. Maybe some settings "droped" accidentally and that's why the color changed.. regarding battery you have a li-ion battery that has working range from ~3V up to 4.2V. it seems you have bought a ni-mh battery that has working voltage of 1.2V so please do not mix or exchange them. If it had some rust it could have gotten water damage but this is always difficult to diagnose remotely. Hope this helps you ;)
@@letsfixitgarage Thanks for response. I never DL the application till now. A bit useless from my perspective. Through it, I was able to switch the colour. So most probably, rust found from water may have mess a bit resulting in settings. Despite the rust, motor still working fine and battery which I didn't change of course, looks have good performances in time [days] and power delivery at instant moment of using. Thanks again for support
Glad it worked :) good luck, if it would stop working you know where to find the answer ;)
Do you know where you can find a parts store for the tooth brushes? I am looking for plastic outer shell case. Do you know where to find them.?
Sorry no. I would look in usuall places like eBay or AliExpress.. or try contacting brown, although I wouldn't put to much hopes in the last one..
@@letsfixitgarage where do you get your parts for replacing parts on the toothbrushes?Thank you for your response. 👍
@@ronaldhowell5831 eBay or AliExpress :)
Good video. Thanks for posting. However my toothbrush will start and run for 5 seconds or less. It has a full charge. So what do you think?
The same issue. It starts by lower and lower run time and then dies completely. Replace the fuse and it will be fine.
thanks! never bothered to use the tester on my sonic-fx until this video. turns out it's only a power button problem! it turns on while the probes shorts the contacts. however, I have no soldering skill and I already bought a new toothbrush, good thing its only $7. I will probably parallel the power button to the mode button and see what happens.
I wouldn't do that.. :) better is to exchange the button.. maybe you can find locally a person who would be willing to do this for you..
@@letsfixitgarage thanks. I tried to use a single strand of wire to jump the two buttons by tying it to the terminals but the buttons are too close to the board, i can't insert the wire.
i accidentally removed the housing cover of the button and it turns to be dirty contacts. the button now works but the motor has become defective, humming and vibrating like a fluorescent ballast. I must have damaged it when I hooked it directly to a 5v 2A power adapter. these toothbrushes should have better seals, waste of nice hardware😞
By testing you should always disconnected the existing power supply and electronics.. playing around with power supply can have unexpected results.. you will be surprised but from my impressions oral-b has better water seal but when it fails water damage is more severe as in Philips.. they have weaker seals but electromagnetic drive survives water damage better :)
@@letsfixitgarage I agree. We have old Oral-Bs but never had related water damage, we simply killed its wireless chargers with our 220v outlets here. Your comment telling me that I should have spent more with Oral Bs which Ive been thinking for the whole day. they have better brush heads. The $7 toothbrush I bought is a Xiaomi, it has a unique motor that I want to see but their brush heads are too simple.
Now I understand what those huge coils are in the Philips! thanks.
Hi, thank you so much for this video. Can you tell me where can I get these fuses, and is it possible to glue the fuse with super glue or something? Sorry, I don't know
Have some fuses in the description of the video although the links are quite old can't find the time to update them., but you can find some type suggestions there, go for 2A fuses and sadly superglue will not work you need to solder them in..
Thank you!
thank you so much, you saved me 200$!, for now I just pushed the fuse down and it worked! any idea where we could find a remplacement part?
Not sure if I already replied to your other comment but check video description, have few fuses linked.
Hi, can I also use an 1 A fuse? Thanks for the video.
I will try to repair later.
Yes, you can. if I remember correctly no load motor consumption is around 250ma under load ~600 so thats why recomendet is 1-2A
Hi,
The base cover flaps that click in have broken off. Any tips where can I order this spare part ?
Sometimes to buy a broken donor brush on eBay is easier then look for new part ;)
Thank you so much! Me and my dad took it apart and he said the solder was really bad on a few of the points. He just reheated the solder on the fuse I think… just a bad connection. It’s lasted for 2 weeks absolutely fine so far! Thanks so much for your video!
Glad it was helpful and you had quality time with your father :) yes sometimes it can be a micro crack on the solder, but this fuse is failing to often in my opinion.. but if it fails you now know how to proceed ;)
funnily enough it has just failed again!! At least it lasted a few more weeks! Will have to replace the fuse as you said!@@letsfixitgarage
I removed my fuse, as pressing it didn't help, and then tried bridging the fuse net endpoints with solder, but now the lights won't turn on. Maybe I was too forceful? Appreciate any advice!
you are our hero
Is a 0805 fuse with 1A good to use too? If yess or no what is the difference with a 2A fuse?
If I recall correctly nominal usage is something 200-300mah. Under load ~ 500mah. So 1a could be enough as well.
I broke the seal that’s at the top of the plastic that lights up when using a clamp to unseal it. Needed minimal pressure. Is there somewhere I can get a replacement?
don't think so.. braun is refusing any spare parts for these or IO brushes.. So your best chance is second hand platforms like ebay..
Hi!
I'm about to order these fuses on aliexpress. What AMP should I order? Thanks.
I'm installing 2a fuses
Thanks a lot from me too ❤
I have the same model, same problem and no warranty! Can you please explain what were the materials you used to attach the new fuse?
Flux, solder and soldering iron.. check some basic soldering videos to get impression of what is needed.. you will need a soldering iron with very small tip and something to hold the fuse in place and depending on eyes some magnification ;)
@@letsfixitgarage Do you have Instagram ? I want show you whether the fuse is the right one to buy.
No I don't use Instagram, but my email is in about Chanel section. Not sure what can I say other than it will be written in the shop site ;)
@@letsfixitgarage I followed your instructions and it worked!! My Genius X is only a year old but stopped functioning properly. I'm so glad I don't have to buy a new one which is expensive. Thank you very much for posting this video!
@@marcraphaeljames good job! Share the knowledge ;) and if you share my Chanel then thank you as well :)
Thanks!
Thanks for the beer :) glad this video saves people real money!
I just tried the "pressure fix" meaning pressing on the fuse with my tweesers, and it is now working again. I will try to report back if it stops working again. I am not sure if this a problem with seating though it should be soldered in .. or if there is a reset. I noticed that some of the fuses that Let's Fixit listed were described as resettable with pressure.
I think they call them self recovering didn't read anything about pressure reset.. but to be honest I haven't tried the recovery "function", how or does it work at all.. for me fuse should blow :) any reset function is a possible failure like in these genius brushes.. please do let us know if it will hold as well. For me it didn't work and I have repaired more than 20 of them..
Hi I have the exact same problem. Connected both ends with a pliers and the motor started working. I took out the fuse before my new fuse arrived. made a bridge just to see if it worked but now i can't get any lights on the brush? maybe I damaged something while taking the fuse? What is the next component after the fuse? I can see 4 volts reach the component labbeled E (i asusme it is next after the fuse) any tips for trying to find out might be wrong? Thank you
Found the solution! did the reset of the microcontroller as described by @AJB and it works now. Thank you
@@ultrixPt nice! Comments are a gold mine in my channel:)))
The same thing happened to me, but I didn't find the comment that describes how to reset the microcontroller. How did you do it?
Look for the comment. It had quite a lot of comments shouldn't be hidden.. simply said the test point is on the right to the main chip but the comment had much more detailed description how to find it.
@@letsfixitgarage
I read pretty much all the comments and couldn't find it. Perhaps it has been deleted. But I found another comment of yours that said that all you had to do was to put ground on the test point of the the main chip and it worked. Thanks.
7:47 what is the voltage after the second smaller fuse? Mine shows a drop to about 1.3 volt after the smaller fuse from the ca 4 volt battery-voltage after the bigger fuse. (I have one that is dead, neither lamps nor any switch working but that the motor and its different modes are startable through an easy touch over a resistor in the vicinity of the fuse you changed)
Well fuse shouldn't have no resistance and no voltage drops. Try to short it out with tweezers and see if brush comes back to life..
@@letsfixitgarage I have packed it somewhere and as soon as I find it I will try it. I was not aware that the part was a fuse before I saw your video, and actually pondered if fuses never had resistance. I will let you know the "test" when I have found the brush. Thanks!
Thanks for the movie. Could you please add the correct name of the fuse? the second ali link is down and the first one does not have a 2A anymore.
thanks for the feedback. will update the links shortly but in principle just look for similar size fuse with 1-2A rating will be much better safety as the squished fuse or a solder short ;)
can you also share the solder model that you've used in this video? :) thank you
Sure, added a link to the description. I really like this soldering iron. Heat up time is incredible, lightweight, a lot of tips and you can even use it from 12-18V power tool batteries with some DIY adapters :)
@@letsfixitgarage Thank you Bro! I've found that my 10000seri toothbrush unit can charge/still can power on but when turned on, it only vibrate under 5 seconds and slow down to turn off as always. Do you know the root cause and appreciate if you can share a workaround for my toothbrush. thank bro a lot!
The same problem ;) replace the fuse and it will be as good as new.
Please provide a link to purchase the part for the repair.
Hi, added link in to the video description
Mine keeps cutting out, fully charged sometimes it will start full power then just randomly cut out, keeps doing it. Do you think this is same issue or different?
Difficult to say. It's possible that the fuse is starting to die. Easiest way to check is to open it up and short out the fuse.
Applied soldering iron to fuse, brush working now. Added some solder to bridge fuse. Will see what happens, hope solder does not come off inside
as i say to everyone fuse doesn't cost a lot and its there for a reason.. my recommendation is to replace the fuse..
If my toothbrush vibrates a couple of seconds 1-2, could it be the same issue? thanks!
yes, high chance that the same problem with the fuse is the culprint
Hello, yesterday I repaired two such brushes, there was no need to replace the fuses, the solder joints were cold, I just had to re-solder them. Everything worked until I put the brush back together... now nothing, dark, dead. Battery charged, no lights, no charging. What could have happened? Regards
Try to shorten the fuse with metallic tweezers.. I had fuses that show continuity but it already has to high resistance and it's not working.. that's why I always replace the fuse with different type..
what is the specific name of the 2 amp fuse please. I cannot find your replacement part online
link under video seems to work or what is the problem?
Thanks for the video! Helped to save mine toothbrush.
Link to soldering iron is dead. Could you post name or photo please of soldering iron you use?
thanks for the feedback. will update all the links this week.
@@letsfixitgarage what fuses do you use? 2a? First link is 0.75A 750MA will it work?
I believe the links have changed quite a lot... Still haven't found the time to go through them, a lot of work at the moment.. I would suggest 1A or 2A both will do the job 1A is more on the safe side but 2A should save the motor as well if something unexpected happens..
Danke!
Vielen Dank im Gegenzug :)
Hello,
I changed the fuse... but I think I touched something by mistake on the board and now it doesn't start at all, no LED lights up.
I have this problem with 2 brushes.
Can you help me please?
Thanks and best regards,
Same happened with mine
A great tutorial, but my situation is strange - I replaced this fuse and after 3 work cycles it burns up again. I also replaced the neighboring one and nothing.
It seams there is a further defect on the board that leads to the burnt fuse..
@@letsfixitgarage Thank you for Your lightning fast reply. However, the solution was exactly as You gave earlier. My mistake was that I gave too much solder paste, so a bridge formed under the fuse - that's why it burned. When I soldered the fuse correctly, the machine came to life. Thanks again for the tutorial and best regards.
@@donlucio1 glad you figured it out :) although not sure if it's permanent fix.. if there was a bridge under the fuse it should have stayed like that bridge is essentially a wire it just jumps over the fuse so it shouldn't burn.. but if there was a bad solder joint it could have affected this behaviour.. hope now it's permanent fix ;)
@@letsfixitgarage I tested 28 cycles of work (until discharge), so I hope it will be okay. THX.
@@letsfixitgarage It's a motor... There is a metal dust on it's commutator creating a parasite- current-flow...
I have this problem happened to my Genuis X for 3 times in 2 years already! This obvious is a product defect! Braun should have recalled all Genius X! I am so so so upset!
hi, can you give me other similar fuses to use pls? Because they are finished. And thanks for this beautiful video!
if you check the link under video it seems to still work. additionally you can check your local electronic shops for similar size and 1-2A fuses. fuse is very simple device so anything that fits in size and amperage will work ;)
It is very meaningful sharing, and I am aware Oral B has the general problem on Genius X model. May I know the part number of the fuse, and I can look for extra help from electric store? appreciate
Sorry don't have exact number it's a smd fuse 2A and ~2mm in length
@@letsfixitgarage thanks for the nice Video. 2A but what ist about the voltage? Im searching for a fuse but Too many options
Usually these smd fuses are up to 24v so any will be good enough. As here we have 5V and current is the main factor..
Is there any chance u have a link to the smd fuse. I am not finding anything. 2A are nominal current? If there ist any possibility please Provide a link
I would suggest asking your local electronics shop for a 2A SMD fuse ~ 2mm in length. There are plenty in China stores but they sell in bulk and you are never sure for quality...
Valeu!
Thanks for the tip from Brasil! And hope this knowledge will bring you the value 10x ;)
Привет друг. Не подскажешь что делать, была такая же проблема, но перед заменой я отпаял мотор, после этого плата перестала включаться вообще, я припаял обратно, но включатся она и не начала. Когда ставлю на зарядку, верхний светодиод моргает на миллисекунду, и гаснет, потом через секунду опять мигает. На этом все. Питание на плату приходит.
UPD: а не, я спалил мотор, замкнул + и - 😢
Maybe it's still repairable. Try to rotate the shaft of the motor. If it doesn't move you welded Motor "brushes" to the rotor. Check my other Braun toothbrush repair video it shows disassembled Motor, it's "brushes" and how to repair it.
