I had a tabletop Kenmore microwave that quite working the sameway. Found
out there was safety microswitch in the door circuit that prevented the
unit from working if the door is not closed. However, like you, the
lights and fan sounded like it worked, but nothing heated. Replaced
microswitch and all is well.

Kenmore over-the-stove microwave/hood has stopped heating. Appears to
run normally, I hear the normal fan and (heating?) section kick in and
out normally, but there is no heating action.

Are there things I can check before hauling it to a repair center?

I'm fairly qualified mechanically and electrically for most projects
but have no specific microwave knowledge.

Thanks,
