This is not safe. If the fan is not running, the magnetron will quickly overheat and be destroyed. We answered this in more depth in the other place you asked it.

SOURCE: Microwave buzzing

It's likely a bad magnetron or maybe the high-voltage transformer. If it's within the warranty period of the magnetron (5 years or less), I would call Sears. In my professional opinion, no one should work on a microwave unless they are fully informed and aware of the deadly hazards and necessary precautions. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your full model number (without the suffix) here: http://tinyurl.com/gv383

SOURCE: How do I fix a Jenn-Air JMC7000 that does not heat up items?

The noise is coming from the high-voltage transformer being overloaded by something shorting it out. Either the magnatron or the high-voltage capacitor and diode. Replace the capacitor and diode then if still not working, replace the magnatron. Its only affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!

SOURCE: Microwave won't heat/Makes buzzing noise.

The symptoms you are describing are typical of a magnetron that has gone bad. Continuing to attempt to use the oven in its current condition can cause further damage. So, I would recommend not using it. Microwave ovens are considered dangerous and repairs should not be attempted by anyone that is not electronic saavy. The High Voltage Network inside the oven has voltage potentials of 14,000 volts and higher. If you feel this is something you wish to attempt, the Magnetron part number is 1156751 and costs approx. $158. Keep in mind, if the magnetron has been arcing and making a burning smell you may have burned the protective coating that lines the walls of the waveguide. If the waveguide is damaged it is not repairable. I do not know if this is a replaceable item on your model microwave. Double check your warranty information and/or owner's manual. In many cases the magnetron is warranted for several years beyond the limited warranty that comes with most appliances. Post back with comments and let me know if you want me to assist you further. In addition, if you provide me with your EXACT model number (located along the door opening) I can narrow down parts a little better. I know this all sounds discouraging, but I do hope I have been able to help you.

SOURCE: Microwave does not heat/cook

hi

power spikes are very damaging to a microwaves internal parts, it sounds like your transformer and/or magnetron are blown. if the unit is out of warranty I would recommend calling a repairman or getting a new microwave (the transformer & magnetron are expensive and dangerous to work on) also get a small single plug surge protector for the new one.

GE spacemaker microwave all seems to be working but won't heat


It is the magnetron circuit that has failed. It the part that generates the microwaves that heat the food. If it is making a loud buzzing sound when you try heating something, then the magnetron is shorted out. The replacement cost for the magnetron is almost as much as an new oven, so it does not make sense to have it fixed. Sorry.

Microwave will not heat


If everything else works, like display, light, turntable, but does not heat, it probally the magentron circuit that failed. It the part that generates the microwaves that heat the food. When it fails, it makes a loud buzzing sound. If this is the case, it not worth fixing since the replacement magnetron cost as much as a new oven. Sorry.

Buzzing sound... Turntable stopped. food heats up but uneven. No microwave fan when heating.. no light inside expensive fix?? Unit is 10 years old


If the microwave oven is 10 years old then it is time to consider a new unit, by your description it is going into cascade failure where different parts have stopped working, the buzzing sound is the magnetron warning you, it is about to fail. The fans job is to keep the magnetron cool while it is running.

Ge microwave jvm160wj01 was working and suddenly started buzzing, gave bad electric/burnt smell and buzzes. Still buzzes and does not seem to heat now.


Sounds like the magnetron just shorted out. Its the part the generates the microwaves that heat the food. Buzzing sounds are a symptom of a shorted mag. Usually not worth fixing since the magnetron costs almost as much as a new oven. Sorry.

Microwave makes loud buzzing sound when on and no heat


Have you tried putting a cup of water in it and cooking on a low power level? If it buzzes only when it is on the cook cycle, that would narrow it down. More detals might help us help you, including the model number.
