Microwave not working. Repairman said not control panel and probably a thermostat. We replaced DE47-20020A thermostat, but no change. Can you tell me what we might need. Not house fuse or house electric at fault.
There are a couple of thermal fuses in the unit that would need to be tested to make sure that the correct one is replaced. When you check them they should read closed for continuity. There will be one exception. On the base of the unit behind the control panel there will be 2 thermostats. One is normally open for continuity and the other is normally closed. You will want to test these also.
