Suggestion, if you don't know the safety procedures to troubleshoot these
devices take it to a service center. They can be lethal when improperly
serviced. Numerous things may cause the unit to not heat. Inclusive of
controller defect, thermal cut-out devices, safety switches failing or
mis-adjusted, defect in the HV diode - Capacitor area, Magnetron, and
Transformer. Of course, interconnects, etc can also cause problems. Again,
unless you know how to work on these items, for your own safety, do not!!

Greetings All,
My microwave oven just quit heating. Before I scrap it for parts maybe
I can instead fix it. When set to defrost the power cycles on and off.
And you can tell by the lower fan sound and the light slightly dimming
when it is supposed to be heating.. It still does this but nothing
gets hot. Whether defrost or full power. So, I think the transformer
must still be getting power. Any thoughts? Do magnetrons eventually
fail? I have another oven that's over twenty years old and it still
works fine.
Thank You,
