Everything operates correctly, except no heat. I can hear a transformer hum,
come and go while it acts like it is working, like it is trying to run, but
nothing heats. I understand electrical systems and have read considerable
about troubleshooting and repair. I just wanted to ask before undertaking
this task. Based on the circumstances with the on and off hum, what do you
think?


** Do NOT even dream of fixing your own microwave oven.

The devices are ABSOLUTELY LETHAL !!
