Question about Microwave Ovens
You can find
helpful exploded view diagrams and order parts by entering your full
model number from the tag on the oven here.
You should also refer to the technical sheet behind the controls, or you can download it here.
A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but a sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound.
Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:
(if it is NOT shorted or burned looking, it's probably fine)
(continuity can be good even though mag is bad!)
