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.
The problem is most likely caused by a defective magnetron that "heats the food" is loading down the high voltage transformer causing it to make a loud buzzing sound. The cost to repair (depending on make and model) will probably approach the cost of a new microwave oven when you factor parts and labor.
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.
I have a GE counter top microwave oven. When the oven starts cooking (the magnetron turns on) the oven makes a harsh buzzing noise. What is wrong and what should be done?
I would first suspect a shorted high voltage rectifier diode or possibly a defective magnetron.
If the noise is just a loud buzz, I would suspect the diode. If it has more of a hollow sound - like someone gurgling into a coffee cup - then I would suspect the magnetron.
Here are some links you or a friend can use for test help, but PLEASE read their safety warnings first:
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.
