*** If you have any "simple" questions, please post them in the comments section. I will try my best to reply back as soon as possible. I have lots of people that request "Special Assistance", or send me private YT messages seeking "Special Assistance" in response to one or more of my over 450 videos, even though I would love to assist everyone possible, and usually I do (which many other YT channels do not, that I know for an absolute fact), I am finding it very difficult to keep up with all the requests, due to a lack of time(working & personal life). Answering simple questions, I will always continue to do, but I have adopted a new policy in which I ask any viewer who seeks, "An Advanced Level Of Help" to post (1) link in the video comment section showing that they shared my Youtube Channel main page with others(posting a link on another website, Twitter, Facebook, etc). By doing so, I will then be glad to assist at a "higher" level. I have no problem helping, but viewers looking for help, should also help me in return to get more exposure for my channel. To take the time to assist someone at a, "higher level" who does not share my channel, simply does not make sense. Help those who take the time to help you.***

As someone with no experience testing a microwave, your video is clear and concise and demonstrates that it doesn't require a licensed repairman. It requires a little common sense and attention to safety.
Thank you for your effort.

Update: I replaced all three parts you explained. Magnetron was burned at the connector but tested good, diode was the issue. I purchased a capacitor and diode together and old capacitor was in spec but new capacitor was better in spec. Microwave is much quieter and heats quicker on foods. Thank you for your videos and giving me the confidence to do this. $70 new parts not used. Praying for 10 more years now. 😆

This presentation is excellent in all respects: communication, filming, clarity, thoroughness and detail. I can't imagine finding a better troubleshooting analysis on microwaves.

[ShaunPeterKelly]

I was a microwave engineer and found this video absolutely correct. I would like to add that keeping the inside of the oven clean is essential. A splash of gravy or food left inside will carry on cooking and eventually glow and burn through the paint to expose bare metal which will eventually destroy the machine.

I've watched MANY instructional videos on repairing a variety of items, even made a couple of them myself, and I have never seen a more clear and understandable one than this one! Thanks for sharing this and my compliments on a job superbly done.

I started in the microwave business back when Litton first entered the retail market I believe in the early 1970's. While not a defect or a repair problem I want to point out the most common error I see people making virtually all the time, this mistake is widespread on videos on YouTube. When consumer microwaves first came out the manufacturers spent millions trying to get the most even 'pattern', or distribution of microwaves in the cooking area. Then some companies gave up and started putting turntables in their microwaves, just about all followed fairly quickly. The idea was to move the food around instead of the microwaves themselves, these days they don't seem to even try to make them cook evenly, depending on the turntable to take care of it. Now the important part: I see people put something in the microwave and put it in the center of the turntable, DON'T DO THAT! The center doesn't move around, it sits there in the same spot, if you have a hot spot or cold spot, its going to be in the center of the turntable. If you have a single small item, a donut, a cup of coffee etc, put it towards the edge, never put anything in the middle if you can avoid it since it defeats the entire purpose of the turntable. Sometimes you have a larger item and you can't avoid the center, but usually in that case you can take it out and change what part is in the center for the rest of the cooking. Another handy tip, if heating up something that takes up a lot of room on the plate, arrange the food around the edges of the plate, leaving the center empty and put that empty spot in the middle, its like you are making it in a ring mold, like a cake with a hole in the middle. In all the years I was in the business I sponsored and attended many microwave cooking schools, this is the #1 handiest tip and most common error when I see someone using a microwave.

I can’t thank you enough . I’m pretty good at fixing almost anything . This video helped me save my $250 microwave by diagnosing a bad door switch . $6 for 2 of them on Amazon . I hope you make some money on this video. My friend is eating crow after this fix. Very good quality video and narrative. Thank you so much !!

In about 6 or 7 out of 10 “repairs” I had success with a different approach. I remove all switches and clean them thoroughly with quick evaporating contacts cleaning spray. Sometimes an old toothbrush or compressed air needed or helpful. Do the same on all other electrical connections and snap-together or push-to-lock connectors. Clean (or replace fuse). Using a blow dryer I go over all wires & components. No multimeter. No component by component testing. Just a “deep cleaning” of the innards. 6/7 out of 10 REVIVAL.

This video is PERFECT for the 3/4 out of 10 when deep-clean does NOT fix the microwave.

Great tutorial. Not needed in about 60% of the cases where MW malfuctioning.

GREAT tutorial for the other 40% ish

[NYCAndi]

This is the most thorough, clear, and concise video for troubleshooting a microwave. All of my questions were answered. Thank you very much!

[Oldguygeek]

OK. I'm pretty handy at all repairs, but sometimes you just have to go to the experts. My hat is off to you. You sure know your stuff. Everything was exactly as you said. The testing helped me discover that all I needed was a $15 diode and nothing else. Saved me hundreds of dollars. You are the best of all the microwave videos that I watched. Period.

[calvinendo]

I like how you take the time to explain how each part works and how to test the part. This video is worth saving if you want to fix your own microwave and save money. Start collecting parts from microwaves people throw away.

[BlakSand]

That's amazing! You've explained the whole story of microwave repair in twenty something minutes! Good job, listen! Thank you!

[RafaelKarosuo]

I really love the fact that you know how many ovens really are, I've seen just a couple and agree with all that you said and even better, learned very good things in the way.
Very good and safer way to discharge the cap, this also could be used for other situations, like old CNCs, have a similar configuration with a high V cap.
Thank you.

[bobe.]

I have watched how to videos on repairing everything from dishwashers to car problems. This video is by far the best. Great knowledge, communication, and filming. Thanks.

[leesimpson]

So refreshing to have a super well done video! Articulate, informative, and no loud music! LOL. Super! You "know your Smoke!" Many Thanks, Lee, Florida

[garycolageo]

The most informative by a mile. Also he tells you what to test first like a flowchart. Now to put it to the test.

[larrywright]

This video is extremely helpful. For those of us with combo microwave/convection wall ovens, being able to troubleshoot and repair saves hundreds in repair bills. I had a voltage spike the resulted in two blown fuses -- still not sure how fuses in series both blow, but....in any event this video gave me the info and confidence to tackle the problem. As a result of disassembling the unit to access the fuses I accidentally loosened a wire on the control panel. Back to this video....helped me find the problem. I haven't been through all your videos, but maybe at some point you could walk through reading the technical schematic for one of these things. Thanks for taking the time to share your knowledge.

[doddanand]

Kudos for this "no stones unturned" thorough video! When there was no power on my microwave, I wasted a ton of time looking at many simplistic videos that stopped saying anything beyond the main fuse. This video goes beyond that. And yes, it was the thermal cut off switch in my case that failed the continuity test and on closer examination had burnt! (No wonder I sensed a plastic burning smell when it went dead). Now I need to order the part. Will come back and update this comment after I fix it and my microwave comes back to life again.
But, nevertheless this is a great video! Glad I came across this.
