Re: 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: You can find helpful exploded view diagrams and order parts by entering your full model number (without the suffix) here:

Kenmore microwave Model No. 721.62463201 runs but does not heat and has a terrificately loud buzz. All lights displays are normal

Hello there:
There's no heat, but it buzzes loudly When the microwave won't heat, but you hear a loud buzz, you usually have a defective power diode, high-voltage capacitor, or magnetron. I recommend that you consult with a qualified appliance repair technician for help in determining the problem and deciding what to do about it.
And if you have your warranty for this you can use it to ok
Hope this helps best regards mike

Noise/humming while cooking; especially popcorn; intermitent on other food

Popcorn is heated by a metallic insert in the bag. This causes some additional power consumption by the magnetron. It is no cause for alarm.

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.
