The buzzing is the magnatron tube juicing too thousands of volts before emmitting the micro-wave radiation to what your cooking that turns molecules 180 degrees around... guess that friction is what really heats it.
radar ovens is what they use to call em and even people would stand in front of big ones to warm up long ago...lol canibles will love that.

Microwave makes a loud buzzing noise


The buzzing sound could be from loose laminations on the high voltage transformer, or from loose mounting screws for the transformer. This requires investigation by a qualified technician as there are lethal voltages associated with the transformer. It could also be from a loose cover. First check that all the cover screws are tight.

Microwave works, new noise


It could be a bad magnetron, or it may be mild arcing due to food particles or grease on or behind the waveguide cover.

No microwave should ever be left unattended while running.

Ge microwave - making noise


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?

Viking Micro noise


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
