3 years later and this video is still paying dividends! Thank you for saving me $150 on buying a new one.
Thanks. I had already called Ninja OEM and since it was still in warranty period, they shipped me a new base unit. Once I saw your video, I figured I had nothing to lose. Bought 20ct capacitor pack and your recommended torx security set bits and went to work when they arrived. Made good progress until I got to second security torx screw in the deep well. Hole wasn't big enough to get screwdriver down to screw. Luckily, a friend had a set similar to allen wrenches and the T9 was able to reach. Made the repair (terrible at soldering) and reassembled. Plugged in and power light came. Pressed single serve button and now it's back in business. Again thanks so much and this video is still helping people out after four years.
As the others have said.... thank you 👍. The Ninja was a gift and used 2 x then DEAD. No more Radio Shack to go to so Amazon to the rescue to get the 25V capacitors.... Working once again !
And since it is basically a viariable speed "blender", the innards could have been simpler to control the speeds without the extra electronics.......
It IS crazy to think how many may be in the trash, because of cheap caps. It seems like a nice blender but a lot of people have this issue with it according to reviews. I'm glad I seen this video because I purchased one of these new old stock and I suspect it may not last long before I have to do your fix here. I may even attempt it regardless knowing one day that cap will eventually fail. A good thing about this blender is it has a very simple pcb so even a beginner could replaced all of the capacitors on it easily.
thanks again.
So glad I found this, thank you! Had the same issue with my Ninja Professional 1500 (model BL770), fixed it in a day with a 50-cent capacitor from a local shop!
The same capacitor was dead in my Ninja. Repair was cheap and easy. THANK YOU!
It’s amazing that so many have the same exact issue. It’s almost like they’re designed to fail like this. 🤔 Glad you got it fixed.
Yes sir, so it happened I'm making my morning smoothie and i go to start the Ninja 1500 watt blender and nothing, I messed with it pressing the power button for all its worth and nothing, then the wife gets up and i say we are going to need a new Ninja, well the look on her face said fix it now, so I looked it up on RUclips and came accross your video. next I ordered a soder kit for $21 then ordered the the connector and figured why not right. so I start to take it apart and I then remembered you said something about the security screw and I was stumped because I didn't have that tool, So of course I did the next best thing and drilled that little sucker out. will I'm now back to my morning smoothie and it's thanks to your video. So thanks brother..
This wasn't my exact problem, but this video was helpful for disassembly. My security torx was a size T-10 however, not a T-9. I went out to Lowes and bought some bits. They did not carry a T-9 security bit in the store, T-10 was the smallest, but it turned out to be the right one.
My problem was that I was foolish enough to spray mine off with the kitchen sink spray hose to rinse it and I think water got into one or more switches. I took it apart and could not find any water inside, put it back together and it actually worked, even though I didn't "fix" anything. Probably just dried off and started working again. I did leave it lay apart overnight and that might have helped. I also worked the switches in and out quite of few times and that might have helped too. Moral of the story, just clean with a damp cloth like the manual says.
Thank you so much for this video. I just fixed the exact same blender with the exact same problem, and now it's runnng like a jet engine. I know this took time to make, and I am so very greatful.
Shakusky Malone glad you got yours up and running again.
Hanx, I'm gonna try to fix mine.
Could a ninja food processor bowl be fixed, the screws look like they have all been broken . When I picked up the bowl for food processor the gear was loose and I could not tighten the screws back in. Not sure if this fixable.
@@DustinRogersinMO thank you!!! Was about to trash mine, then I decided to look if it could be fixed. Found your video and I have the exact same problem. Swollen capacitor! In your opinion, is 10v better than 6.3v?
@@curiouskitten use whatever capacitor you have that has the same capacitance value and at least the same voltage value. A higher voltage value will hold up better, but are typically more costly (when buying millions for manufacturing), so the manufacturers typically go with the minimum spec/price components.
Hi Dustin. Thank you very much, ours did the same, I found a second hand 10V 1000mf capacitor, and we have our Ninja working again, saving us about $300. AUD although we run 240V mains it was still the came capacitor, we just have another 2 large resistors on the board. Thanks again.
Thank you for the instructional video. I purchased your recommended equipment and fixed my blender!!! Thank you.
cawley great. I’m glad you got it fixed.
Dustin, thanks for this video. I had a BL770 that I was fixing so in watching your video I was immediately suspicious of the electolytic caps (I continue to see bad electrolytic caps from the "Capacitor Plague" which just keeps on giving. )
I did look at the 1000 uFarad 6.3 Volt but it was good. However the other two 100 uFarad 25 Volt electrolytics read open with my ESR meter and would have probably read open with a standard meter. They didn't blow out the top the way I'm used to seeing but leaked out the bottom where the leads enter the body so visually there was no clue but they were open. I replaced them and the 1000 uF as well since it was suspect. The board was acting normally. Power light would come on and the power buttons would light up as you change the power settings but no motor! In tracing the power flow through the two relays it suddenly turned on. Then I found that by tapping the board under the relays I could make it come on. So naturally thought "bad relay". There are two as you look at the bottom of the board with the 6 pins down. They are both Single Pole Double Throw. Naturally I unsoldered and opened up the left one and found it to be pristine! Then I opened up the right one and sure enough, badly burned contacts. The relay is a 12 Volt HF115F which is available on eBay. It needs to be the one with 8 pins however. Most I see are from China but I didn''t want to wait so ordered one from California off eBay. Here's the same one from Mouser: tinyurl.com/y2v3f2jw
Uh oh just did some measurements and it's not exactly a perfect fit. So there's going to be some modding needed!
So if you have a Ninja BL770 and all the lights work properly but doesn't run but runs if you bounce it it's probably this relay.
Richard Sato good work on troubleshooting and thanks for the tip.
Thank you!
Thanks for this, I overlooked the capacitor in mine and was focusing on the microswitches. This video made me take another look at the cap, saw it was slightly bulged so I swapped it for a 16v 1000uf and we're back in action
Hey Buddy Thanks for your help, My system was doing the exact same thing as yours. The same cap was popped, I also could not find the 6.3V,, I put in the 10V cap everything is working fine. Once again THANKS !
Had the exact same problem. Good point on the electrolytic capacitors being a common source of problem. I’ve fixed many devices especially TV power supplies by replacing. Likely a Ninja design issue or bad batch of caps in this case.
Thank you. Followed your introductions and I have a working Ninja again. Capacitors came in a pack of ten so nine more for future fixes. 😂
Thanks a bunch - I just fixed my ninja by installing new caps. Same symptom, no power.
What kinda caps?
This video is what happened to my blender. I bought the affiliated capacitor and installed. My blender is working again. Thank you!
Sweet. Appreciate the affiliate purchase too.
Thank you, I have the same model, will be fixing as soon as I buy the capacitor. Thank you, you are amazing.
I have the exact same ninja blender, almost 9 years old. Nothing wrong with it. I want to heavily modify it so that I can fine tune its speed control. It original has 3 speed controls. It has some sort of a chip (could be a micro-controller) at the center of the circuit board. I like how the manufacturer etched the labeling on the chip to prevent reverse engineering. But its no bigge, just need to cut open bunch of wires and connect it to a mini Arduino board and customize the programming for fine tuning its speed.
S To sounds like an interesting project. If you go through with it, make a video of the process.
Great suggestion! Just swapped and it works beautifully 👍
Dude thanks for the video. I swapped out the capacitor and it fixed the blender. $3 fix. Thanks for your help.
Thank you so much I am going to try and fix mine. I thank YHWH bless you for your skill
Great Great video, so easy to follow. I have the same unit, light doesn’t come on but the capacitor isn’t swollen, could it still be that or possibly a different problem
Edit: This was a followup to a post I apparently posted under the wrong vid.
Hmmm, maybe a little luck. I now realize that on my old one I was pushing the buttons harder and thought they were not making contact, feeling mushy , today I was more careful in checking and found the buttons although having some extra play, do still hit the board. So, maybe that unit might have the capacitor problem you showed us. I'm still hoping you might advise regarding my previous questions since once I get in there I will of course then have a more sure analysis.
I just watched a repair post about a diferent unit and learned that my problem with the newer Ninja is the blade assembly in the single serve is rocking. The other optional mixing containers work fine, no wobbles, grinding or smell of electricity. Can't yet find the second single serve and can't remember if it had its own blade assembly cap.
Thanks for a great video. I repaired mine and the problem was one of the (2) HF115F relays.
Thank you Rodger for sharing that I love doing stuff like that thank you thank you 👍
He said 'Thanks Steve' 😂
That...was...awesome!!
Good day sir.my ninja blender 1500 watts was plug at 220v.i have open blender machine to check the damage and saw the regulator capacitor explode.the prob is i dont know the wattage of the capacitor so i can replace it.can you help me with this? Tnx in advance
holy crap she lives! it worked
It worked. Thanks for the "how to."
How I wish you just live next door!
Hey Dustin, thanks for taking the time to make this video!! Question: Does the Capacitor have the ability to work sometimes and then wig out and stop the power supply until you toggle the power switch on the wall? That's what is happening to mine. I get a solid red power light, I press any of the buttons to blend and most of the time it starts blending then I get a total power-out. Toggle the wall power switch once and the Red power light comes back on and it repeats the same cycle. Occasionally it works and we get a full blend - but that is getting rarer now. Any help would be greatly appreciated. Thanks
If you have to turn the outlet switch OFF then back ON to make it work, it is more likely to be a capacitor's issue. Start with them, the big one first. Good luck
Someone asked about the Varistor "small ceramic capacitor between the 2 wires and the yellow part". It's a 10S271K and available all over. I was unclear how they worked. This is from Wikipedia "Varistors are used as control or compensation elements in circuits either to provide optimal operating conditions or to protect against excessive transient voltages. When used as protection devices, they shunt the current created by the excessive voltage away from sensitive components when triggered."
So it makes sense that it blew up. Might have also blew when it was plugged into 220 VAC. It does have a zig zag trace on the board.
Hi Richard! By any chance do you know the specs for the varistor for the Ninja SS401 ? I can`t find it anywhere. Mine is burnt exactly where the code is written and I can`t read it.
Hi Dustin, i have the same blender. Mine’s power light is turning on fine but none of blend buttons are working, so not able to use either Pulse, Dough, Blend, Crush, Single Serve. Could you share some thoughts on what could be wrong with it and what can I try to fix? It was working fine for past 2 years but today suddenly all buttons stopped working. Power led still turns on though.
Thanks for that video man... the issue I'm having with mine is the the lights turn on but it's not blending, Do you think it could be the same kind of repair?
This repair was for a dead (no power) unit. If your lights turn on, its probably not the same problem. Typically its a problem with the safety lock system. The lid has to be pushed down and base aligned correctly for the pins in the lid and pitcher to activate the safety switch in the base.
Thanks for this. Mine started working intermittently only after a couple months. If I shake the blender I can get it to run which led me to believe it wasn't a capacitor and instead switch related.
Thanks for the video. I had mine misaligned.
Thanks for the video my dads ninja blender doesn't turn on hopefully it's something similar fingers crossed
Good video man. Way to edit and fast forward. Thanks.
That is so great instead of throwing things away. Our light still comes on but when we go to blend, it makes noise for 1 sec then stops and power light goes off. Ninja won't even address it as it isn't under warrantee anymore. Would you know what could be wrong?
It could be a similar issue. I’d recommend pulling it apart to check for swollen capacitors.
Thanks Dustin!
My capacitor was also swelled. Found the exact cap. and replaced it today. Bingo! success !
Only thing the single serve button acts a little goofy, but works fine. Maybe the push button switch underneath is sticky? Or not lining up correctly?
Thanks again!
Gods Bless Brother!,
This is exactly the kind of video we need to watching, direct to the point, show where the problem is and really is a very good!!!! Congratulations 🎉👏🎉
Great video and info. Where do I find a bit to remove the security screw? My wife will think I'm her hero if I can get her blender fixed!.
There's a link in the description to some security bits. Thanks for watching, and enjoy becoming a hero.
Thanks Dustin ! Great vid and job. Enjoy your Ninja !
Thank you so much 👍👍👍👍👍
what an interesting post.... wonder if I can learn some of this stuff myself??? hate waste
The beauty of a repair like this, and most repairs actually, is that the item was destined for the trash anyway. You can’t hurt it anymore than it already is. If you mess up and are unsuccessful at fixing it, you’re only out a little time and a cheap replacement part, but you’ve potentially gained knowledge and a skill.
Thank you sir.
Thanks for the video - just fixed mine following your instructions.
My ninja has a motor problem I believe. It starts to runs very slow then the power is tripped off. What do you think? Replace the whole motor?
Thanks for sharing
Thanks for the video. My BL610 only works on the bullet functions. If you try the blender power button blinks red. I’m told it smoked one day after heavy use. Is there an internal thermal fuse? No visible damages on the IC board; all safety switches work.
Ideas?
Question my single serve and power work but all the other buttons don't would I look at something else to be the issue. Thanks
I have a different MODEL but same issue > will do ....thank you sir !!!
Great ! Thanks !
My gray toothed wheel on the base that spins the blades in the pitcher is just free spinning... not keyed to the motor shaft?
So the motor spins but not the blades.
Suggestions?
To clean the big jug after making baby food, I added water all the way the top. It over flowed into the unit and after I shut it down it won’t power back up after 5 minutes, 10 minutes, 30 minutes and 1 hour.
I made sure all the water is out of the vents during that entire time.
Is there a way to reset the unit? Or just have to wait until it’s all dry to try again?
Thank you. Very good video 👍
Connected a 110 v blender to a 230v power. Blender stopped soon as pressed power button. Can it be fixed?
Good day Sir, thanks for the info. I have that exact blender,but with mine the power button keeps blinking and only the single serve cup attachment is working. Please help
I seem to remember another comment below describing a similar issue where one attachment worked but another didn’t. I’m not sure if that commenter ever found a solution.
Dustin,
Great video. Thank you very much.
Would the capacitor be relevant if the power LED lights up and some but not all of the buttons work?
Pushing either Button #1 (Dough) or #2 (Blend) immediately shuts off the Ninja after spinning the blade for about 1 second. Other buttons #3 (Crush) and Pulse work OK.
I've got your recommended solder kit and capacitors, but not sure if this is a different problem. Any suggestions would be welcome.
Thanks again for an excellent video.
I’m not sure. Mine wouldn’t do anything at all, so yours has some other issue. It could be some other capacitor that is failing or it could be the switches themselves. It’d definitely be worth getting it apart to see if there’s anything obvious (swollen capacitors, cold solder joints at the switches, or loose wire connections).
Hey love this video, but what do i do if only one of the blender cups doesn’t work and the rest do? The little cups works and the one for the dough works also, but the big food blender cup doesn’t. What do i do to fix that problem? Would it be the same as what you did on this video?
Ayisha Dawood no. There’s part of the cup that engages a safety switch when you lock the cup onto the blender. You’ll just need to inspect the base of your big cup to see if something is broken off or missing.
Ninja BL 490. I can’t figure out how to separate the upper part to access the motor. I was able to remove the bottom base with the specialty bit, but that’s how far I was able to get. Do you have any ideas how to access the motor?
I buy about 3 months ago working well after that power on but running I don't know what happens at all
I have this blender, and your video was great, but my problem is the single serve button. It lights but does not activate the motor when pushed. All the other buttons work.
Were you able to fix it? I have the same issue
Hi mine is BL700 When I start it,it goes off immediately...it will start and off in seconds
Where can yo get capasitors.i have a Ninja Blender the don't start.power boton blinking.
Check the video description
Hello Dustin, I have the same Ninja model. It has power, but when press any of the button the motor is not turning. Button #4 seems turn the motor on when you press, but don't have enough power to turn the top blade. What do you think wrong with it?
Question...
The power comes on but the other buttons don't turn on...
Help please!
I wish you were close by. I'd ask you to repair mine. I was just about to blend some Tomatoes when I found that mine is not working. Yes I'm not happy.
Me too!😫
Was making salsa, poured everything in and then had to mix it al together in a huge bowl with an immersion blender...SUPER MESSY!
Hello Dustin,
My wife attempted to use a similar blender requiring 120V with 230V outlet, it currently not working any pointers on how to fix it?
Does the blender indicate that it will work on 230v? Some are dual voltage, but if yours isn’t, it may have been damaged by plugging it into a 230V outlet.
The power will come on ours but when pressing any spin mode, the blades will spin a couple times and then it starts buzzing continuously. Any ideas?
Potentially a different capacitor, but not sure. It’d be worth pulling apart to see if you see anything out of the ordinary.
Show how to unscrew the button and restore the rubber ring I can’t unscrew it
My BL770 blender is making a loud screech when used . i want to check the Motor bearings and gears. Has anyone removed the Blender Motor coupler that connects to the Blender Pitcher
Ninja BL 490. I can’t figure out how to separate the upper part to access the motor. I was able to remove the bottom base with the specialty bit, but that’s how far I was able to get. Do you have any ideas how to access the motor?
I’m not familiar with that model. Sorry
Any chance someone has fixed the gears in the gear box on one of these. Ours turns on but doesnt spin the blades, so think it is worn gears inside possibly?
I have a Ninja blender, all the lights come on but the motor wont turn on please help
Unfortunately my problem is one of the 3 pins in the bipolar transistor has burned out (for some reason) ST 8550c. Wondering if I can bypass it or how to fix it : /
Brother i want the complete circuit of this model, how to get one..mynwas fried due to high voltage ⚡
I put my 120v ninja blender into a 230v socket and it blew, how do I fix it
Change the fuse.
got a B700 that doesn't work and the motor seems locked up (can't manually turn the shaft). were you able to manually turn the blades/shaft prior to your repair? just curious before I get around to working on mine.
I could turn the motor (blades) before the repair
H i have ninja blander 1000 wattas but it not working . I opened it and found this little piece that I swapped out is broken and the size is 10v 470 uf , but I didn't find the same size. Can I replace it with a 16v 470 uf ???? please you can answering me
You should be fine replacing a 10v 470uf with a 16v 470uf. As long as the capacitance rating is the same and the voltage rating is equal or greater to the part being replaced.
Can i send you a photo of my chipboard to see if can identify anything amiss. Capacitor doesn't look swollen. Acts like lid not on. Tried all connections and used chopsticks to replicate the pushing onto connectors but won't work. Will on my other Ninja.
Won't let me attach photo
Can I email you?
@@tracyhodgins1912 just upload to imgur and post the link here. Not sure how much I’ll be able to tell from a photo.

What is clock ic number ? In my ninja bl685 clock ic need to replace but can’t read it
Is it obvious if the capacitor is swollen?
Usually
The link beneath the video for purchasing a replacement capacitor at Amazon takes us to an $8.99 version. Is it a mistake, or has the price risen that much since this video was posted one year ago? Thank you.
The link is to a set of 10 capacitors (89¢ each), which is about the only way you’ll find them sold unless you go to a local electronics supply store that has them available individually. Likewise, you can order direct from an electronics supplier like digikey or mouser and buy just one for 60 to 90 cents, but you’ll probably end up paying $7 in shipping/handling charges.
Dustin: possibly the microswitch to internal cups is broken (not working cups) ...please let me know what is the series o model to buy and change? Thank you.
Not sure. You’ll have to remove the switch and try to find a comparable match. Ninja will not sell it separately. You’ll likely have to try to find it from digi-key or mouser
You can also try find the wiring to the switch or where it hooks to the control board and temporarily jump that connection to see if that gets it working again before you try to find a replacement switch.
Nice work. I have a Ninja BL660 1100 W Pro and I use it everyday. Unit runs great except where the 'fan' mechanism ties into the cup blade is worn from my daughter putting PB in her smoothies. Worn on both the blender and cup side. If whatever is in the cup is too thick for the motor to spin, the blade is designed to 'skip' so the motor can continue to spin. So now everything spins but it doesn't connect to the cup blade. Has anyone replaced this? I refused to throw this blender out!
David Linder I have not searched for them, but I suspect that you’ll have to replace the cup itself. I’m not sure that they’ll sell the replacement coupler as it’s a sealed unit through the blend cup.
I have a bl642w1 1500W I relocated and had not used it for over a year, plugged it in no power. Opened it moved around a few contacts and it came on but turns slowly then stops and powers off. Went back in and noticed the same exact capacitor was swollen, changed it but I'm still getting the same problem. I noticed a smell after it powers off wondering if it's the motor.
It's possible that it's the motor, but I'd check the blend cup to make sure that the shaft spins freely. It's possible that the shaft in the cup is bound up or sticky or something which could be straining the motor.
Also, since you said you moved a few contacts and it powered up, I'd look for broken or cold solder joints on the circuit board and touch some fresh solder on those joints.
I looked at the solder points on the board they all look good. I ended up changing out all the electrolytic caps 2 more 100uf 25v but still nothing even though one looked like it had a leak at the bottom. Doing this from my dining table not the best setup to try tracing. It's definitely a power output issue, with the bottom cover off I can jump start the motor on the lowest speed with a quick spin but if I press a higher speed it chips out and powers off.
I have similar Ninja blender , it turns on when you press power and it's blinking red light on power, but when I press any buttons it wont turn at all. I made sure the led and that little pin is being pressed with the led closed perfectly. What could be the problem please . thank you in advance .
blinking is always the cup or lid not being on properly
I have the exact same blender but the capacitor looks okay no bulge or anything. Could it be faulty anyway? Nothing looks burned on the board
It’s possible that it’s the capacitor, but the only way to know for sure would be to remove the cap and test it with an esr meter ($$$) or solder in a new cap ($) and test it out. It’s a very common failure component, so there’s a good chance that’s the culprit, but I can’t guarantee it. I have seen capacitors fail that have no physical deformation.
I have the same Ninja Blender. It works except when we place the single serve cup. The button is lit up but does not function. All other buttons do work with the larger blender, as well as the one your showing. What could be the problem?
Same as my problem
hellow can you tellme the number on the 'scr' the black scuare and 3 pins
I took it out and last it than you
I have one of these lenders the LEDs turn on as normal but the motor won’t move what do you think my problem is
Darwin Maldonado I believe there is a switch that is actuated when the pitcher is locked in. I suspect that switch is not working properly. I gave this blender away, so I can’t verify that unfortunately.
Do you think it capacitor works for the BL493 model? or where can I locate the voltage for it to properly replace the piece (if needed)?
I’m not familiar with any other models. I was just given this one to troubleshoot. The process of checking capacitors will be the same on any type of circuit board. If you find a bulging or leaking capacitor, you’ll need to replace it with one that has the same capacitance value and an equal or greater voltage rating. Most capacitors should be marked, although it may require a magnifying glass to see the markings depending on the size of the capacitor
