I lost heat on my microwave yesterday, think simple before going for the more difficult solutions. As with all electronic based equipment, do a power down reset by pulling the plug and reinserting again. My machine came back to normal and save me getting a hernia carrying it to my workshop. Should be #1 on the check list.

@@davidshields7072 Thank you. I had to use the circuit breaker as there was no plug access unless I remove the microwave to get behind it. Circuit breaker in the off position for a minute and microwave still wouldn't cook. Thanks for the suggestion tho. Moving onto the next remedy.

Great video, thanks. My microwave stopped heating, but the lights, sounds, and spinning tray still worked. One of the three door switches had a high resistance so I replaced all 3 and fixed the issue.

@ 2:05 I noticed a couple of regular looking small fuses on the back of the small circuit board there... I didn't hear those mentioned in the video. Do they go sometimes too and what are they?

[@gmcbride6306]

GE 2.0 Countertop 9 years old. Sometimes heating. Now not heating. All my parts tested good. With further research I came across the Humidity Sensor connected to control panel and mounted to the side away from main components. This will stop the heating (magnetron) . I don't see testing info on Repair Clinic. eBay had the part $75. Replaced Microwave.

[@austin508]

1) Diode (One way continuity) 2)Door switch/Switches 3) Magnetron 4) Capacitor 5) Tansformer 6) Control board

[@CENTAUR559]

Symptoms: microwave has time, buttons work (except for #3) and functions almost as normal when entering cook time. Once entering cook time, the number counts down. But.. The turn table doesnt spin, the fan does not turn on, and the food does not warm up after it being counted down. Prior to this, for the last several weeks the fan would turn on when opening the door, but it would still turn on when the door was closed and it was set to cook.. but that fixed itself and it started working fine. What could it be? Fuse would mean the whole thing wouldnt work, right? the fact that most things work except for the fan, heat, and the turn table seems like it should be specific.

[@dianewacker]

One of the two thermal switches is a normally open (controls fan) and the other is a normally closed (runs microwave)

[@james77011]

This was very helpful... Now I will fix my neighbors microwave 😃

[@West_Coast]

was it too hard to install a simple self diagnostic in the microwaves...

[@bghydrohurtme]

One more tip! Please check the POWER LEVEL. We replaced a bad capacitor on a Samsung microwave and the power level was at 0 after the electricity had been disconnected. We thought the microwave was still not working since it was not heating. Once we set the POWER LEVEL to 10, it started working!

[@autovale3595]

How about the Panasonic inverter Microwaves which have the integrated capacitor/transformer/diodes? Are you doing a video on those?

[@Celestials1aurora]

Y’all try unplugging it ( close door first ) and plug back and then try. It worked for me.

[@agracer1000]

Just tested 1 thru 5 and they all seems to be ok. Microwave made a horrible screech noise and stopped heating. Is is possible the Magnatron will still have continuity as you showed and be bad? Just to be clear, there always no electrical smell and I found another video to test the transformer and it is OK. I could not find any thermal fuses anywhere. Any other suggestions?

[@new-knowledge8040]

With the parts that I removed from an oven that was placed at the curb to thus be picked up and deposed of, I replaced the door micro-switches, and the AC main fuse. That got the oven up and going again. Total repair cost $0.00. The plate rotate motor also died at one point, so I took the motor apart and repaired it. Total repair cost $0.00. This 2004 stainless steel oven of mine was a demo oven, or so they said, and so it only cost me about $40. In truth, it was not a demo, butthe keyboard was only half working. I fixed that by cleaning the keyboard connection contacts. Total repair cost $0.00. 2019, and this baby is still running and still looks almost brand new.

[@new-knowledge8040]

​@@TomNouri Not quite sure what you mean. If it is a response to me sounding like I am bragging a bit, well years ago I slowly fell into a semi-coma state across an 8 year period, then I spent another 8 years relearning and recovering after the cause of the problem was discovered. In turn, I am very familiar with what was experienced by many other poor folk as was covered in the movie "Awakenings", staring Robin Williams, Julie Kavner, Ruth Nelson, John Heard, Penelope Ann Miller, and Max von Sydow. Other than that, despite being a high school dropout, and a once dementia victim, I did manage to independently discover the phenomena that is today described in Einstein's theory of Special Relativity(SR), and I also independently derived all of the SR mathematical equations. Not bad for a once vegetable person. So I am kind of proud of any of my achievements these days. Check my YT videos.

Older GE microwaves are lasting longer than newer ones. Maybe better to repair than replace.

[@davidf1985]

My 2003 Whirlpool overhead stopped heating today. The only feasible fix for me is #2, check the door switches. I assume all the parts are different now & an exact replacement part is no longer available. Per online, an oven should last 10 years. I guess I got lucky, getting 18 years from mine.

[@lfuentes4098]

I replaced the switches when my microwave kept popping the circuit breaker. And it worked for a couple more years. T starting tripping the breaker again and so I thought, time to change the switches. It worked for a day and when I opened the door without stopping the microwave it tripped the breaker again. No matter what I do it doesn’t work. So I thought. Maybe I need a new latch holder since the plastic looks worn. Ordered one and put that in. Now the microwave sound like it’s on as soon as I close the door. The lights on, but the turn table is not turning nor is it heating. Not sure what that’s about. But I’m guessing I burnt the new switches. So I’m replacing the monitor switch again and hoping that resolves the issue. If that’s not it, I think I’m done because everything else is too expensive for my 2014 microwave. 😂 Any suggestions please leave them, thanks.

My more than 40 years old microwave suddenly stopped working. When I opened it, I have seen, that the fuse was black. So I bought a new fuse and hoped it will fix my problem, but the new one spoiled too. so I know now there is another problem and even if I like to repair it, I can`t, because there are no parts to buy for this old device anymore. To bring it to a repair shop will be too expensive, so sadly I have to say goodbye to my microwave, which worked so fine more than 40 years.

[@SoulFire209]

The goal of a home warranty company is to never pay any of your claims. They rely on mountains of fine print and want to blame you for any issue that arises. That's how they are profitable. Your only options are to argue with them endlessly or cancel your contract. In my opinion and experience, they are never worth it.

[@OriginalMergatroid]

How does half wave rectification double voltage? How can you increase voltage without amplifying? The transformer is increasing the voltage, the diode is just half wave rectifying it. I mean, unless someone can show me the math proving half wave rectification will increase voltage.

[@channelview8854]

It's very common in electronic and been done since the earliest days of radio. Basically, you charge two or more capacitors in parallel with the rectified AC. When the AC wave reverses, those capacitors are discharged thru diodes but they are in series because of the circuit configuration. It's possible to have 2X, 4X, or pretty much however much multiplication you want. Because there is no free lunch, current output is inverse to voltage multiplication minus minor losses in components.

It sounds like the microwave is working intermittently, it could be a tripped thermoprotector or defective thermostat. Could also be the touchpad, control board, or magnetron. You're going to want to troubleshoot these parts to see if they are faulty. Double check your socket wiring to make sure it is getting power.
