My Kenmore Over the Range Microwave (model 665.60609000) is making a loud buzzing sound and the food is not heating. It started after a cup of coffee got overheated and sprayed/poured out of the unit. Any idea what the problem could be?
This is a strong indicator the magnetron is fried, also! this is the most expensive part to replace in the microwave oven, and in most cases cheaper to replace the whole unit.

You have burned out the magnatron (heating element) which is common on GE microwaves. most service companies will charge about 200-250 to replace it

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.

The noise is probably from the high-voltage transformer. When it
is overloaded, the excess magnetic field it produces vibrates its wire
coils. Odd that it only happens for a brief time. It is
either defective itself (in which case it may go a long time) or it is
getting overloaded by the magnatron/capacitor/diode on its output (in
which case it will get worse shortly)
Hope Ya Fix it

Sounds like the magnatron (the bit that creates microwaves) could be goosed. Remove outer cover ( Isolate from the electric supply then remove screws at bottom on the sides).
Find big lump that says on magnatron with model nos etc on, any good electrical supply shop ( Maplins etc) should stock new one.
It is easy to change. It took me about half an hour having never done one before.
Buyer beware the price of the parts could be in excess of a new microwave.
Shop around
