SOLVED**Microwave stopped working. Loose or bad Thermal Fuse!
HTML-код
- Опубликовано: 5 сен 2024
- My microwave stopped working while my wife was using it. After checking the breaker box and realizing that no fuses where tripped, I decided to take the microwave apart and see what I could find. I found that the thermal fuse was loose and just needed to be secured. It is also possible that you may need to replace your thermal fuse.
**Since posting this video, it has been brought to my attention that you may have to discharge the capacitor for your own safety.*
I recommend you have a professional look at your microwave but if you are adventurous like me, please make sure you unplug the microwave before you take it apart. Also make sure you stay clear of the capacitor.
Just wanted to post here in the hopes that I help someone that had the same issue I had with the Samsung Model #ME21M706BAG. Microwave stopped working randomly. Took it apart and checked the fuses and they were fine. Left me scratching my head. Found this video and a similar part on my model and sure enough, even though it didn't LOOK loose, after I fiddled with it the microwave worked. I love the internet, thanks for uploading.
Thank you for posting your experience and helping someone else.
I had a similar problem with our GE microwave and never would have been able to fix it with out a video like this. I was actually looking at new $400 microwaves and decided to check RUclips. A $12 thermal fuse from Amazon did the trick. So, thanks!
Thank you so much for this feedback! I started this channel to help people and comments like this remind me of why I take it extra time to film what I do. Thank you again!
Bought a "as-is" super cheap... matches red/black decor. Got it home and looked inside.... boom! It was the ground wire somehow was disconnected. Works perfectly! Thx for the tip!
Very cool! You are welcome! Thank you for commenting!
That part is a thermo safety sensor, I replaced the one in ours four years ago and it has worked perfectly since, liked the video
Good info. Thank you!
Thanks, I couldn't get the cover off until you explained sliding it back.
I have a Frigidaire microwave that just went out. I checked it, and found that a fuse blew. I replaced the fuse, but it won't run. The light stays on like it is on, but won't run. I checked all of the door switches for continuity. And they were good. I'm Lost as of why it won't work.
Awe man, that sucks. There have been some microwave repair people that have also commented on this video that I hope will see your comment and be able to help you. You may want to check the comments and reach out to them too. I hope you get it running.
Which fuse did you check? If it was the narrow cylindrical fuse that Brian points out at 4:19, I have the same issue on my Samsung. I was sure this fuse had blown, and because it's cheap to replace, I broke it open to see if the if the wire had fused open (I didn't own a multimeter at the time). The wire was fine. It turned out that the thermal fuse described in this video is the issue, which I was able to determine because I had bought a multimeter in the meantime. The only reason I haven't gone ahead replaced the thermal fuse and remounted the microwave is that I think I ought to know the underlying cause.
That unknown part is a thermal switch ...typically a high heat safety which opens on high temp and shuts down the control circuit
Thank you Kirk!
kirk chapman what could set it off? I’ve got into a baked potato trend recently..cooking a couple at a time, for an average of 11min and it steams the heck out of the interior walls/roof even when I wrap them in paper towel.
My problem actually started though, when my finger “stuttered” while hitting the start button. Causing it to start/stop in a flash which feels like it may have tripped something. Has happened many before but this time no deal. But again, LED still goes on when first plugged in , just like in this video..same exact deal. I have an Oster#OGG61101, if your familiar with it? AND THANK YOU ROB FOR THIS VIDEO!!!
LongDongSilver78 yea for real I got the oster microwave not sure of model number but it has the mirror finish. Anyway mine is doin the same just recently about 2 weeks ago. I might just go with this vid. Can’t hurt to try
Kirk Chapman Hello😊. I'm curious if you're related to a Ron Chapman here in Buffalo NY. He's a very good man that I was blessed to meet and know here at a meat plant in Buffalo NY.
Please show in your video how to correctly "de energize" the internal capacitor that stores thousands of watts of ac power & could potentially kill someone if they're a "DIY" type of person that has little knowledge of how these things work. I used to be a HVAC tech in my uncles business & thats one of the first things he taught me when removing the cover off a highly electrical energized piece of equipment. As he pointed to the capacitors that vary in shape & size from round & tublar to being odd shaped they can easily be identified. He was "old school" & worked alot of things "HOT" meaning they were still energized or still had electricty or some of other form of electrical power running thru them but while I was a apprentice. great video though! very informative, thank you & the best to you & your family!!!
Super important advice in your comment Todd!! Thank you. Since releasing this video, I've had more knowledgeable people like yourself point out the importance of correctly de-energizing the internal capacitor. Thank you!!
This is a great video except for one thing. Viewers need to be warned about the high voltage capacitor, which can deliver a lethal shock even if the appliance is unplugged. You can simply avoid touching the capacitor, or you can discharge it with two well insulated screwdrivers or similar tools; anything with a thickly insulated handle and a long thin metal part. There are videos on how to do this, but the basic idea is that you touch the end of one screwdriver against one terminal of the capacitor, then place the other screwdriver so that it touches the other terminal, while at the same time laying it across the first screwdriver, like an "X".
Appreciate the words of wisdom. Other experts have said the same warning and I thought I had pinned one to the top a few years ago so viewers are warned. I will try to pin this one too! Thank you for commenting and giving us wisdom.
The loose piece is a thermal fuse or high-limit cutoff. If it fails you need to replace it. It fails like any other fuse to prevent damage to the microwave or prevent a fire. Lots of appliances that have heat have them,, like ovens and dryers.
Thank you for educating us!
I have possibly a similar situation. My fuse looks similar to his where the one connection looks brown inside. Is that showing something overheated or is that normal?
Have checked the 3 door switches yet, but did change one of them out about 2 years ago
@@MichaelSilliman74 Use a digital muiltimeter to check for continuity, i.e. that electricity is able to flow through the fuse from one of its spade connectors to the other. Put it on the lowest setting for Ohms, usually 10 Ohms, or better yet, right next to that is Ohms with Tone. Put the black multimeter probe on one of the fuse's connectors and the red probe on the other. If you get a tone, the fuse is good. If not, it's bad.
Thanks a bunch brother, after watching your video, found that I had the same issue, fixed it up and tightened it down, works great.
You're welcome brother!! Thanks for circling back and letting me know this was helpful!!
I really liked your video. So very helpful. I woke up this morning and the microwave was working and then it just stopped. I hope mine has the same problem. Ugh. Thank you !
Thank you for the kind words. I hope your microwave is working now!
Was that the problem?
That sensor that you put back in looks like one of the spade connectors was burned up on it unless it was bad lighting & camera angle.
i like the Fonzie approach ...Just smack it and sat haahhh!!!
Lol, yeah, I usually try that first! 😜
all i did is set it for 5 minutes (nothing in it) so i could use it as a timer while i made some tea. but halfway it just shut down, no lights, no numbers, no heat, NADA. and now i can't do anything to heat up my food! and this is my BRAND NEW microwave
Wow! Sorry that happened to you. Did you take it back to get a refund or exchange?
Wow! Sorry that happened to you. Did you take it back to get a refund or exchange?
By now, you've discovered, in the instruction manual, NEVER RUN A MICROWAVE EMPTY.
Unless you want a boat anchor. It is NOT a timer. Buy a cheap timer.
Public schools........
I stop using my microwave altogether because of what it does to my food. I use my toaster oven instead. If I have to use something big I will use my conventional oven. The microwave ruins my food because it heats it from the inside out making the food hard in the center area. My food also TASTES different from my toaster oven and my conventional oven. The taste is much more normal and better than the microwave.
Great job B Rob 👍🏻
Thank you! I love these types of comments😀.
If you take another look at what you put in place it seems burnt the Thermo sensor has to be changed, I could see it in the video But great video by the way. and always discharge the capacitor first.
Thanks for the info and yes, I have learned that you definitely have to discharge the capacitor first. Safety first!
Cool video that thing Ground look like Mosfet Transistor, your Video got lots of info did help me, I did replace G E Microwave did have a Bump so I didn’t know how to remove the Cover and hit it with a Hammer I never open a Microwave before I always deal with Vintage Receavers and Tube Amp and Tube Radios Bravo.
Cool, thank you for the info and positive feedback!
Thanks for the video. I love the disclaimer....FYI, or disclaimer, I pulled out the wisdom teeth in my attempt to repair the microwave. . 😉 thanks again.
😂 Love this!
How to open the star screws ?
Thank you for sharing!
My pleasure!
I had a similar problem with a similar oven/microwave set-up but it is a convection/microwave. I am not sure if I should spend $100 for a GE tech to come over plus pay for parts and labor, or if I should just replace it with a regular microwave GE. The replacement would be another $500 if I include the installation and new trim kit. I read it is usually the magnetron that breaks which is an expensive repair. Any suggestions? It only worked for three years.
Thats a tough decision because you may have the same issue if you get the same one. Can you find a cheaper, good quality repair person? Sorry you are having this issue!
I have 2 LG microwaves, one from 2012 LCRT2010ST and one from 2017 LCRT2010ST/01. They both run and have lights, but neither will heat. The 2012 unit has a ceramic line fuse with 250V 20A. The 2017 unit has a glass fuse with 5000 V 0.95A. No one sells the 0.95A. The glass fuse was visibly blown, but replacing it with a 5000 V 0.9A fuse did not correct the problem. I replaced the ceramic fuse in the 2012 unit with the same result, ie, still running but not heating. I was wondering about the thermal fuse but don't know where it is. Microwaves are supposed to last 10 years. The first one lasted five years. The newer one died after 4 years. I don't want to replace the magnetron, but is there is any chance I could get these working by replacing some other fuse?
Marie, so sorry to hear that you are having trouble with your microwaves. I hope a more experienced viewer will see your comment and help you with your issue. Logically I would assume there is a fuse issue but I'm sorry to say that I don't know enough about the issue you are having. If anyone who reads this can help, please reply to Marie!!
Great video!🙂
Thanks! 😊
welcome
Hey, Rob thanks for the great videos dude, just tried that fix and still, it doesn't switch on. No power whatsoever. I have checked the fuse by the way and bridged it just to make 100% certain thats not the issue. Any bright ideas, anyone
Awe man, thats a bummer! I got lucky trouble shooting this microwave but I will research and let you know if I find a possible fix for yours. What brand is it and whats the model number?
@@BrianRobinsonCoaching Mine is a Samsung Model: ME0113M :-)
Throw it out and buy another one, it's a goddamn microwave for Christ's sake, you can get a nice one at Walmart for 50 bucks.
@@tampabaybuccaneersfan7904 I believe his Samsung is $250 , so probably a tad nicer than the 50 buck ones from Walmart you keep buying for your trailer . Ours was $399 about 15 years ago and just had to put a $50 magnetron in it and it's working fine again . Not much to a microwave that can go wrong so they are simple to troubleshoot . One word of caution though , just because it is unplugged doesn't mean it can't cause you serious harm or death . The power supply and capacitors can store a lot of energy so one must still be extremely careful when disassembling .
hi there. i have a samsung microwave. Microwave sometimes has no display, plates spins automatically and sometimes it just works perfectly. door switches(3) all working check. what could be the problem ? main fuse is NOT blown checked
light only blew yesterday
Sorry but this is above my technical microwave abilities. Hopefully some of the true microwave repair persons that have commenting will see your question and help you. Sorry I couldn't help!!
HUGE ADVICE BRO",EXACTLY WHAT WAS WRONG WITH MY "LG MICROWAVE " THANKS FOR YR TIME,SAVE US SOME $$$$YOUR EXPLANATIONS AND TIPS WERE SPOT ON GOOD 👌 👍 👏
You're welcome! Thank you for leaving a comment and letting me know!!
Looking at this I can imagine how many people throw it away and spend hundreds on another for a simple issue.
True!
Had exactly the same problem, improper attachment of the thermal fuse. Fixed it temporarily the same way. Still failed intermittently after a few days. I suspect the thermal fuse is bad and intend to replace it.
Wow. Mine has held up, so I am fortunate. Thank you for commenting and giving us your experience.
*Almost went to look for another video because you have 2 ads going on a six minute 45 second video. My problem is the fuse. I keep replacing the fuse and then it shuts off after one time or maybe 12 times who knows it differs. The weird thing is I take the fuses back to Ace Hardware and they test positive! No real electricians around so nobody has a clue. I don’t see a fuse like mine on yours but I will look to see if everything’s grounded thanks A lot!
Sorry about the 2 ads. RUclips does that on their own. Thank you for leaving a comment and I hope you find the solutiion. When you do, please leave a comment so hopefully others can be helped. Thank you!
11.24.2002 I came here because I have the same model microwave, you neglected to mention if your re attaching the thermal fuse worked ? .

...should have discharged the "HIGH VOLTAGE CAPACITOR" before sticking your hands in...even unplugged they store enough voltage to teach you much needed (evidently) lesson.
Good to know Jared! Does this also apply to inverted microwaves? Thanks for educating us!
good comment
Hi Rob. I have LG smart inverter Microtron oven. It stops within 15 seconds. Can you tell me please what I can do to fix it. Thanks.
Hey Yousra, I'm not sure at this moment but maybe some of the technicians that have watched and commented on the video will chime in and help you.
@@BrianRobinsonCoaching okay Rob
Replace HV Capacitor!
Alert!!! Before replacing Old Capacitor discharge it for safety
Thank you so much !
You are welcome!
B-Rob:. Thanks! Great help to me as I go look for my microwave issue. I have seen warnings about charged caps and suggestions to discharge them - thoughts? Anyhow, thanks again and Merry Christmas.
Awesome. I'm glad to help. I didn't realize how common this problem is. I hope you had a good Christmas. Thank you so much for commenting!
This thing was designed to get loose over time.
I fully believe that! Thanks for commenting!
yiup that's what it is but they(that heat button) burn up for some reason, look at the wires.
Gotcha. Thank for the info!
Does anyone think a cut wire to the plug the microwave is plugged in will fry it ? I really don't think so . Fuse is good
Thats possible but I'm not 100% sure. Hopefully someone can give you a better answer on here.
Brian, thanks for sharing your experience with us. I might have the same issue with my microwave. I think it's the same model except that it's a built-in like yours. I'm almost 70 now but I used to love tinkering with electronic stuff but my health will no longer allow it 😞. Anyhow I'm going to try to get my nephew to do this 😂. Thanks 👍.
Rubber gloves always! Discharge high voltage capacitor!
Thank you for commenting and educating me and others! Safety first!
Same problem on my LG
I hope you were able to safely fix it.
That it's a thermostat
Thank you!

I think the microwave has died because it doesn't work anymore the battery works on the microwave because Plus the man banging on the microwave it makes me laugh LOL
I have no idea what compels some folks to put up a video on how to repair potentially lethal appliances without even knowing what a thermal sensor is, but you should.
👍
Sir I have bromlem but fuse is ok still dead what should be please reply?
You may have to call a professional. I happen to fix this by toying with it. I wish I could help you more but I want you to be safe too!
Nice job! Thanks
Thank you!
I had an issue with my Kenmore microwave, I was just heating up oak meal and its just stopped working. What's your advice for me
Which Kenmore model is it?
@@BrianRobinsonCoaching Kenmore models: 790.8033, Microwave Hood Combination
Although I did work on mine myself, I was about to go get another one to replace it. It is dangerous to work on these yourself because of the electrical hazard. For the record, I'm not telling you to do that because I don't want something to happen to you. I found this link after I saw you message yesterday www.hunker.com/13408001/my-kenmore-microwave-wont-turn-on . You may have to call someone to fix it or replace it.
Why do my fuzes look so much bigger? Is this not the fuse
😮
What did you use to remove the “star shape” screws. It looks like one of those anti-theft hex screws used in license plates.
I believe it is a torx bit. Here is where you can buy one if you need it from Walmart. goto.walmart.com/c/330645/568840/9383?veh=aff&sourceid=imp_000011112222333344&prodsku=37469085&u=https%3A%2F%2Fwww.walmart.com%2Fip%2F37469085
Thanks dude
You're welcome!

The anti-theft Torx screws can be removed using a very small flat-bladed screwdriver. It'll fit in there. Even better, sometimes the little center anti-theft pin sometimes breaks off. If that happens, you can just use your standard Torx.
Question, will a microwave stop working if you leave the door open?
It shouldn't stop just because you leave the door open.
thanks guy
You're welcome Big Joe!
Thank you!
You are welcome! Thank you for commenting! I like to know that I help.
that door gets slammed a LOT. My microwave is almost identical. A GE. Identical problem. I'll have to go inside and look.
I hop[e it works for you!
Thanks brah!
Thermal fuse
👍
yiup, they like to burn up
Hope you have a multimeter to save you from a shocking experience LOL. Good luck on your repair work in the future.
Man..sounds like I got lucky. I think I will leave this up to the pro's next time!
You are handsome! Thanks for the video!
😀Thank you. Thank you for commenting!!
discharge the cap dude
Thanks. I've actually pinned another comment where someone suggested this to keep everyone safe.
How did you know the internal fuses weren’t working?
I actually banged on it and it worked then stopped again. When I took it apart is when I saw that there was a fuse problem.
Every time you turn on the microwave, after a moment it short circuit/shutt off. That means an electric element is overheating and the fuse could not protect it so the system shutt off.
This guy is dangerous and could identify a thermal couple or over temp sensor for a ground and didn't identify the dangers of the capacitors look at Jack Jensen replied and his link.

This is not right

Samsung is piece of shit don't buy that. I had 15 years old daewoo that heats better than brand new Samsung. My Samsung broke after few months.
Wow. Thanks for sharing your experience.

Some kind of grounding mechanism??? It's called a fuse! You really shouldn't be trying to make educational videos on microwaves.
