- It Happened Again, Our microwave oven stopped working right in the middle of heating ham and cheese Hot Pockets for lunch!
This video shows how we fixed the microwave oven using simple troubleshooting techniques.
Repairing your own microwave oven and save you a ton of money and save the earth by keeping it out of the landfill. Most microwave ovens can be fixed for only a few dollars.
The most common problems with microwave ovens are found as a faulty fuse and/or micro switch.

I'm a 70 year old widow. My Husband always turned to videos for how-to on something he hadn't tackled before. I've already replaced the fuse which was fried. Now I'm going to attempt to check and/or replace the switches. I'm hoping to fix as my microwave is only about 5-6 years old and it's a Whirlpool over-the-range. So, it's too heavy for me to remove & replace which means not just buying a new one but getting someone to install. One thing you did not mention in the video that I'm concerned about is my door has settled slightly almost 1/16" (I tend to pull down & out to open) and therefore has a small amount of play. I suspect that may have caused the switch to fail. I'm going to investigate further to see if I can find a fix for that and then replace the switch(s). Thank you for the informative video, very helpful. Wish me luck!
1:42 "Bleed capacitor." = => Should be 'bleed resistor' internal to the high voltage capacitor. Must short the high voltage capacitor any and every time the microwave has been plugged in to test its operation.
Great instructional video! Glad you emphasized safety first!
Up 3am trying to find the problem with my 400 dollar Panasonic inverter we only had for 3 months then my Wife yelled from the inner lines of the creepy floor boards of our turn of the century pillars of a foundation, did you fix the microwave yet while I'm tuned in to the only guy that made since all night the Guru brew shouts out to you my guy now I can finally go to bed its now 7 am. ITS FIXED
that guide by Samuel M. Goldwasser is incredible
Enjoyed your microwave repair video. I'm an electrician in aerospace that's being asked to troubleshoot microwaves,and floor scrubbing machines as well as corded and cordless tools. Been in the trade 30 plus years. Still learning new things every day.
Keep up the great content.
Hi can l ask you a question please?
Easy to follow, detailed, saved me the cost of a new microwave when I put a $5.00 new switch in. And one less thing in the landfill! Great stuff!
This was awesome. Not only helpful, but I felt like Ron Swanson was teaching me. Great job.
This is the best damn thing. I was ready to call someone to come out, then I watched this and got the courage to unmount the unit from the cabinet and tear into it. Checked switehes and fuses, couldn't find anything I could say was not working, put it back together, and viola, it worked! Saved me at least the cost of a service call, and all the headaches. I'm very grateful!
Simple easy to understand and not rushed which is the part I appreciated the most.
I found that your methodology, and your easy to understand, clear and concise explanation of what you are demonstrating, to be perfect for me. Your dedication to pointing out potential safety issues is refreshing. Thank you.
You have the vocal dynamics of someone telling me to take a number at the DMV... but somehow your voice is so soothing. I could listen to you talk about microwaves all night. 🙂
For real though... very informative and yet entertaining. Thanks for the help!
Verified what I needed to know- simple enough microswitch i am replacing is charred- will check all of them- just trying to help out a single mom to save her some $$. Appreciate you taking time to explain safety- too many folks don't understand the issues with capacitors and other components with microawaves---
Thanks for the great video. Finally, someone who isn't imagining young children tuning in regularly to watch their how to videos. Great work, straight forward, through, and none of the unnecessary "righty tighty lefty loosey this is what a screwdriver looks like"
type of delivery.
On to your next video... after the microwave guro dude.
Proper Teacher, would love to work with this chap, knows what he's doing & very entertaining lesson, well explained,!! Thank you GuruBrew.

You asked for a comment... How's this? Dude you are a badass. I enjoyed that far more than I needed for the information I wanted to get out of it. Not sure about using a screwdriver on that size cap, I have a fused thick wire and it still gets pretty hot at just 700V when I am working on audio amp caps. But also, I once welded a wrench to the side of an track (military personal carrier) above the battery because I touched the wall and the positive terminal at the same time with a 9 inch wrench. Threw me across the track as well. I'm... uh.. skittish when it comes to stored charges, lol.
I loved how you showed such nice up close clear video of where you were placing the multimeter probes. I've seen other instructional videos where they explain but I can't make out where the meter probes are touching. I have my own field of experience & knowledge.....but it has nothing to do with electronics/electricity. Plus you talked very clearly and unhurriedly. Thank you
Excellent, straightforward instructions, with sufficient warnings about injury/death for the novice. Outstanding. Thanks!
Good video. Really love the dead-pan delivery of the instructor.
Thanks! Our sharp Carousel decided to keep running after the time I had it set for. It stopped when I opened the door,but began running again with the door closed. I followed your suggestion and tested the door switches. The middle one was bad,so I scavenged one from an old oven I never got around to scrapping. No cost,1/2 hr down time, and my wife is happy! Win,Win !
15 min video is what you need when you want to learn how to properly do something, not 1-2min. And if you want less, you can always accelerate it when playing or pass the parts you do not want to hear/see. Congratulations, you come very understandable, you take your time to teach us through the process. Thanks for doing that for us, newbies.
Thanks GuruBrew. Your excellent video allowed me to replace a $5 micro switch in a 6 year old wall mounted microwave oven, probably saved me $200+!
Thank you, am following you, and enjoying from Tanzania
Thanks a lot. Better than the fearmongers. So simple!
Thank you for your video. Explained a lot and I was able to fix mine. Knowing to drain the capacitor help immensely too.
[delivered entirely in one singular tone] "Anyway, let's get this installed. Or, no... This one. We don't want... We don't want that one." *flicks old, broken microswitch out of frame and grabs replacement*
Oh man. This guy is my hero.
Wow, it’s amazing that a little curiosity problem solving and critical thinking you can fix pretty much anything. I fix my microwave by opening up the front and seeing the burnt wires leading to a thermo switch. The microwave would work when I reset it by unplugging it but when the machine started to heat it would shut down. 3.75 part and it worked perfectly. Saved over 400 on purchasing a new one. It feels so good to fix something on your own. Almost like you’re sticking it to the man...
You my friend have a very relaxing voice easy to listen to. Thank you so much for the video. Glad you mentioned how dangerous working on a microwave can be, especially draining the capacitor.
Great job thanks
Outstanding tutorial! Thank you for taking time to explain the safety steps in addition to the expert troubleshooting logic. Fantastic!
Nice explanation for fixing my microwave. You saved my marriage😂
Very thorough process for troubleshooting microwave issues. Some people demonstrating repairs on CZcams assume the watcher is more experienced and skip some information,; but as I stated, this one is very thorough.
Thanks for posting this highly informative review.
My 21 year old Goldstar stopped working today; my wife immediately said, 'Just buy a new one'.
Given that 75 to 80% of microwave issues are merely fuses or microswitches (thanks for that piece of information, GuruBrew), I'm gonna have a go at fixing it rather than automatically throwing it in the trash and buying a new one. Women!
Your videos are a breath of fresh air.
Andy Erb Thanks, Very much appreciated!
Thanks for that lesson on microwaves. I now know a generic micro-switch can be configured to be default open or default closed. Cheers
An excellent, no nonsense, clear analysis of common microwave issues, very useful to appliance owners who may find that their older model microwave is superior in certain features to a newer replacement. Thanks, GuruBrew.
I could see clearly what you were doing and you kept it simple. Also gave percentage on fuses and micro switches! In bad videos not enough light to see clearly what they are doing ie hands in the way. Keep up good video productions. Please do more videos with different fault finding.
You're absolutely correct about the "generic" style microswitch. Even though your bad switch didn't have the normally closed contact present, the "generic" plastic cases diagram showed it present. I just replaced a 15 year old over the stove microwave, that I know I could fix but I was getting tired of lifting the 70lb stove without the extra help I could use. The replacement was much lighter which is good for me, but maybe not so good for longevity. We'll see.
hankus253 Older appliances last much longer and that is a fact. I replaced all my kitchen appliances 13 years ago and everyone of them has had issues or been replaced. When I was first married we bought all second had appliances and they were still working until we got fancy with new ones.
We love your videos! Anymore wine/beer videos?
Michcouple14 Thanx, I will be doing more wine and possibly beer when I start new batches in the fall.
I appreciate the level of training that you brought to this video. I have worked in electronic assembly for several years but never learned how to read a volt/ohm meter. Thank you so much.
I liked your explanation while testing. Voice and presentation style are wonderful. You can be a great Professor, because you have the knowledge, presentation style, you provide your listeners what to watch out for, and also give them what they will need in the real world. Great job!!! You taught us how not to make a mistake when connecting to a 3 prong micro-switch, because connecting to the upper terminal will change it a normally-closed switch. Thanks for taking time to make such a clear and useful video and sharing, Sam!!!
I feel like I just had Sam Elliot teach me how to fix a microwave
Holy crap.thats what I was thinking did you know Sam Elliott is from California his accent is actually a mix of Texan and Northern california or some shit. His co star in his last film mentioned it. Bradley Cooper?
Lol
Yes I also thought of Sam Elliot when listening to you. Anyway, I’m a novice at appliance repairs. I mostly install new. I looked up your video because a customer wants me to troubleshoot his microwave before he decides to replace his non working one. I can tell you, the easiest thing for me is to sell him a new one so, that’s what I will do. I just want to say that I appreciate guys/techs like you that know what the hell they’re doing with components. Thank you for your very informative video Sam
Thank you , it is sad that parts and even some techs are ablivious about micro switches
Pretty cool Sam Elliot reference. You know there is more than meets the eye and ear with tha 50 year old behind the counter of the repair shop. A very good lesson to never be too wise to yourself to atleast not explore what other people say. He did end up with a 3 prong switch... vs a 2 prong for the old one. I watched another video before this and the dude said unplugging one end of the micro switch will ensure a more accurate reading when testing with a multi meter... he never said why but I am curious... but if that is true... then a 3 prong in some way could make a difference... thank you for the video sir dude... I learned a lot already and there is still 5 minutes left of the video
Much love. God bless! Jesus and The Holy Ghost!
Like the video. Its getting harder and harder to find a local parts place that have people behind the counter who can make change let alone have a clue about their products.
Metallurg33 That's so true about making change. I used to seldom check the change I received back and just put it in my pocket, but my wife taught me to count it as she has proven that I often get short changed. Funny it was always in their favor!
Hi from the UK .Good Video. You gave clear warnings about the dangers of messing with Microwave ovens
The best microwave testing and fixing I saw, so far. Cheers
I am not the confident man he warned to stay away, but after watching this video, I have the knowledge to at least figure out if it is a total loss, or my appliance has repair, most do when you know,and I will be watching to learn! Thank you for sharing your knowledge!
Sir, this was awesome to see. All this time I did not know what the speaker function was for on the digital or analog multi meter, so thank you for showing me that as well. Also you made it very easy to understand the micro switches. I also appreciate how you used the piece of heat shrink tubing to safely wire off or protect off the third prong of the microswitch in your video. Thank you very much for crafting this video.
Thanks for the concise instruction. When I punched the 2-minute button, I saw and heard a spark, seemingly coming from the entrance of the power cord, as it simultaneously went dead. I'll definitely discharge the capacitor.
Nice video. Diagnosed a faulty switch. Simple $7 fix. Many Thanks!
Don't know what's with the dislikers; don't electrocute yourselves. The rest was great and your tests insightful.
Love your dead pan delivery. Your explanation of the problem was clear and a good listen on this subject compared to the others. You’ll be my go to guy on how to fix things from now on.
Excellent video. Clear, humourous, safe, informed, experienced, concise and covered all the bases well.
My problem was one of the micro switches was open circuit. One on order so await delivery. Fuses were checked as per video, so am hoping it works when installed. One of the very best instructional videos I have viewed.Congratulations; oh| and a complete lack of BS!!
Hi thanks so much!!!!! You saved me thousands!!! It WAS the fuse (only $2.00). Also thanks for the info on how to discharge the capacitator!!! I was VERY careful thanks to you!!!
Fabulous walk-thru on testing & diagnosing typical microwave function failures!!! The BEST i've experienced as a home body troubleshooter trying to repair what i can before considering 'throw away & replace'. Thankful to be able to subscribe & view more & more!
I enjoyed your video, because you speak clearly, slowly, and use proper names of parts it's easy to follow and understand (unlike many of the other CZcams fix it guys). So much so it makes me want to fix my Panasonic microwave which stays on after closing the door. Great video, thank you.
Much appreciation for the referral to Samuel M. Goldwasser repair guide. Very informative.👍🏽
Thank you very much for a straight forward video of the basic first level failure of a microwave.
Awesome, you saved me a lot of hassle. Several years ago our microwave stopped working. So i took it to the garage and took it apart. Never done this before but i found a fuse. Thought maybe thats all it was. Yep bad fuse and it worked. Now door switch is bad so i will do the same again. We didn't like the newer microwaves, too cheaply made and looks cheap. So i get to save it again.
I appreciate your laid-back style. Very calming and thorough.
Yeah, agree with you on the appliance repair person....the guys in my hometown are the same. Thanks for this info...I have already fixed the microwave in my RV (door switch) and now I'm working on the one in the house. Again, thank you.
Great video. I know next to nothing about electronics and small appliances and I found this video easy to follow and very informative. Turns out all my fuses and switches are working properly, so I still don't know how to fix my microwave; but I've ruled out a lot of possibilities and gained some basic understanding of it's operation. Will be back to this channel for future repairs.
Enjoyed watching, very easy to understand and thanks for the repeated warnings about the danger of working on Microwaves
This is so worth a try before you plop down several hundred dollars for a new one. I have salvaged several microwaves this way. I keep these switches and fuses in "stock" because I have had to do this repair several times, especially on the "over the stove" microwaves.
I can listen to you read a microwave manual sir. Now on top of that you are helping me get rid of my headache with this GE MW... You are the absolute best brother. I subscribed, liked and shared. Thank you for you help. 👌🏿👌🏿👌🏿
This was very well done! Safety and science combined. Not only how to use tools but very filmed, sound and info very helpful.
Well done. I especially liked that you took the time to explain that there is a universal (both NC NO) microswitch. Shorting the capacitor was also properly stressed. Nice job.
Sat here and watched the whole thing!
Got a job to tackle, thanks for putting this up!
Love your low key and attitude. Great safety tips. I repair myself and just like to get a preview before I go out. Good job!!!
Great that you focused on the most common problems with microwaves. Thanks a lot.
Excellent 'dead-pan' humor which i Feel. Your environment is great. You easy delivery and precise explanations, with cautions, if necessary, is my cup of tea.
Honest broadcasting, simple to digest, easy on the ears and eyes: Man, you've done it all. And aside from the Shop Vibe, for you to get onto the You Tube Empire, i give you great kudos, for bigger, but unseen, business and media sense. Thank you most kindly, sir...I'm passing on your connections to my friends, for a down-to-earth Fixing Situations. Love it....Passing on YOur Word.....
Great tips on handling a microwave repair, I found your instruction informative and easy to follow! Much appreciated, thanks for taking the time to share!
Well done, as you spoke slow enough and were concise and thorough in explaining each step. Especially when stressing the safe practices in first disarming the capacitor b-4 doing anything else!
Really helpful video, covers every step needed, and informative. Explains steps clearly, a rarity. Great job
Thanks for showing how to test switches using multi-meter. Too many people have a meter but have no idea how useful they can really be . . .
A great reference for a microwave, we have the same kind as you with a bad case of intermittent power. Thanks! I'm a new subscriber.
The safety briefing we all hope we could get...practical, informative & direct. Thanks!
Video also is very clear and you know exactly what part you’re talking about and you show it very clearly
Scott Sanders
Places emphasis on safety and explains procedures clearly with good camera angles to see and follow each step; very good video
As a former serviceman on Litton’s I was impressed by the simple yet thorough explanation for lay DIY’ers. Good vid guy.
Good Info.
Excellent video. Appreciate the safety warnings, especially the heads up on the big capacitor. Also appreciate the extra lead for the fix it guide at the end of the video. He honed right in on the problem fast and efficient and safe. Thanks alot.
Easy to follow video, my microwave which I can't replace (not made anymore) and really love comes on when the door is open, just bought door switches and will replace when they get here. Have subscribed to your channel, thank you for a great tutorial!
Great video, not rushed good information ..... good camera work staying in focus, zooming in tight on the areas that you’re working on so that it is clear what you are doing and talking about. Thank you.
Great job on explaining. It took several searches before finding your video.
I really like your easy delivery, story telling and link to Goldwasser; you got lucky on the fix. I hope I do, too.
Third video I checked. This is the BEST.
Detailed, safety shown as priority. Well done! Very good quality of video. Thank you.
No nonsense, helpful information and warnings. I feel like my microwave can be fixed without a huge bill. Thank you so much.
Well done video, very helpful and very informative. I particularly liked the step by step troubleshooting methodology that zeroed in and pinpointed the problem. Thanks GuruBrew!
I greatly appreciate the attention to detail.. the well organized and efficient delivery.. and most of all, the authenticity of an experienced technician bringing good teaching to those of us, like myself, who benefit greatly from the guidance and suggested order of operations along the path of
least resistance as to arrive at the solution with greatest speed, ease,safety, and accuracy of a thorough and properly executed repair. Thank you, sir, for your experience and expertise. You make technical skills and applicable knowledge , available to those in need. I will return for more wisdom in the future because I observed a professional with years of experience skillfully and competently articulate just how to be handy with microwave, "not working so hot"...lol.
Love your subtle entertainment as I learn something new!
Thank you so very much for taking the time to make this video. It was not only very helpful and informative but it also saved me a lot of Money!!!!
I feel pretty confident now in testing my microwave since watching your video. Thanks
Very useful info, easy to listen to, no fluff, and good photography. Thanks for a well-done video.
Thanks for the lessons about fuses and microswitches. I'm not sure yet what's wrong with my microwave, but now I can make some sense of what's in its guts. Hopefully I'll be able to keep it from becoming landfill. (This guy is the real life Ron Swanson from Parks and Rec!)
Very helpful! I knew about the fuse as a possible problem and was able to fix one machine with the correct sized fuse. I didn't know about the microswitches. Now I can fix my current machine. Thank you!!!
I was able to trouble shoot & repair my 30 year old microwave/ convection oven. To the point video! Thank you.
This was exactly what I needed to see. Super helpful to know that there are indeed some generic/standard parts used across several brands.
Thanks so much
Good video! A clear and concise explanation of where and how to troubleshoot micro-switches and fuses. Thanks for demonstrating the discharge of the capacitor and using the multimeter.
Dr. GuruBrew Thanks for taking the time to make and share this video tutorial. Excellent presentation. For us working stiffs you make a huge help for us do it yourselfers.
Thanks to you, I just fixed my microwave! It was the third (bottom) microswitch. Again, thank you!
Gave very good instructions. And I am a woman. Yay, fixed. Very much grateful. Thank you so much.
great video, helped me figure out what was wrong with mine. better to fix it than it ending up in a landfill. keep up the great work man.
Appreciated the insights to troubleshooting microwaves. Appreciated the information on checking switches and the fuses... especially the switches.
You are a truly amazing teacher - I learned and enjoyed this thoroughly
simple straightforward and helpful
