20 Most Recent Kenmore 63792 Microwave Oven Questions & Answers


It's not a door switch the door switches will keep the oven from even turning on when they aren't closed that's why they use switches, it's most likely the magnetron, it's probably made by Toshiba or deawoo, they're both junk parts made from unpurre elements and made to die and early ***** at your cost. You can thank those manufacturers for planning this into your appliances.

I have this same problem with a similar Kenmore elite, it tested good when I bought last week, heated a cup of water to boiling in 70 seconds or so. I used to help rive around my next door neighbor who was a microwave repairman, I learned what went wrong with them and typical fixes. Back then there was only 1 brand being sold the Amana Radar range which sold for well over $1000 for the cheapest models. They had no sensors like they do now. Only a few things could go wrong with them making them simple to make money off repairs. So I do know my way around a microwave, I sell 4 or more a month and repair maybe 1 or 2 a month. But this one has me stumped. I took a look inside and cleaned the grease off the cover right away as I always do. I also had to repair a few tabs that hold the panel and top cover piece. .after the cleaning I reassembled it and tested it again. It worked fine. Then 2 days later I found the missing platter for it and went ahead and cooked a frozen macaroni and cheese family sized dinner to give it an official test to see if I should just keep it and sell my current oven. After 5 minutes it seemed like it was cooking kind of slow. It was in my garage during this so I didn't notice any smells till I checked on it. It should have been completely thawed but not hot yet (if it was in my 17 year old GE) so I turned the dial to cook a frozen dinner and not just times cook. I watched it and that's when I smelled the burnt plastic smell, strong on the right side. But that's also where the light bulb is, that bulb only comes on when the oven is cooking?
I put may face closer to see inside and only saw the bulb, I took it apart and tested everything and the only issue I found was the humidity senor is reading low resistance by about ? of what it should be. This would not account for any burning smells since it's on the left and only tells the oven how the food is cooking. It would either keep cooking longer or say it's done before it really is depending on how the resistance is read by the cpu connected to that sensor.
the diode checked fine, the hf cap is fine, the transformer was good, the magnitron was not shorted and tested within the speced ohms range. Ok controls work and I can set it to run at different heat settings without any problems. I can hear it kick in a run for 50% when I set it to that setting, but it still isn't even getting a cup of water hot now. All wires are connected good, the entire board works properly, the readout and button select and work. I haven't tried the fan yet. I'm going to check it out but I did doin it by hand when the forget was off and it spins freely. I don't have an extra humidity sensor to test it but I'll get one very soon and report back here. I was hoping that this was a problem that was specific to my model and hoped to find the quick answer but this is a common problem in general which seems to have only one typical response provided by every single person but a select few. The answer given 95% of the time is buy a new oven! That's not the answer to fixing the oven. I'm pretty sure that anyone who comes here looking for a solution isn't hoping that 9 out of 10 answers will be buy a new one or they would not be here in the first place, they'd be out buying another oven that will likely break even quicker than the last one that they are dealing with fir the first time after 15 years. New microwaves are junk, I fix more ovens that are 5 years or less old. I sell ovens from the 1980s that still work perfectly! Every Samsung is junk and every sharp and magichef are still going strong 30 years later. It's because the magnetron is built using pure elements and not made by Deawoo or Toshiba, that's why Panasonic's last so long too, they aren't using substandard parts to make their expensive ovens. This really has become a race to the bottom when it comes to making new appliances these days. All are built with end of life factored in, at least until they figure out that they can no longer cheaply mine those elements needed and find a new way to make things using even poorer substitutes.

ill post my findings as soon as I get this figured out it can't be that hard, there's only a handful of components that can burn or give off any smell at all I suspect it's the light bulb and there's something else unrelated that's dying. My guess is the magnetron or the transformer is faulty even though they read within ohms specs. Magnetron made by Toshiba, I've replaced many toshiba on deawoo magnetrons.

The internal fuse may have opened.

Very dangerous! Do not use it like that. I heard of a chip shop owner who has overridden the micro switch to make the oven run constantly. He could then just put food in and take it out without having to open and close the door. He eventually last his hand due to the exposure to the radiation. It must have something preventing the micro switch disconnecting. The micro switch is inside one of the holes where the closing mechanism pushes in.

Unplug the power cord and make sure it will come out easily when you start to take out the mounting screws.There are 2 or more screws in the cabinet floor above the microwave. Be ready to catch the microwave once the last screw is removed because it will drop in the front. Then lift the back of the case off the tabs on the wall mount bracket and the whole thing is in your hands.

door (micro)switch is bad... 8 bucks each replace them both

I'm afraid the only solution might be to remove it from the wall and reinstall it.

You will need the installation instructions. If for some reason you don't still have yours, you can find or order them from Sears Parts Direct Web site, where you can also order parts and accessories.
