I have an over the range microwave that started to hum loudly when turned on this morning. I know that the magnetron turns on and off based on what power is selected so I put it on 50% and let it run. Sure enough the loud humming was on 20 seconds and then of for 20 seconds. Does anyone know how to diagnose if I have a bad magnetron vs some other issue?
