I have a GE spacemaker JVM3670SK06. First issue I had was the microwave worked but wouldn’t heat. Thought it was the door switches since those failed before. Turns out it was the thermostat sensor or thermal cutout (whichever you want to call it). I replaced it and the microwave heats but the fan runs nonstop. I ordered the other sensor for that and installed it. The fan doesn’t run anymore but the microwave is not heating! I really dont’ know what to do next. If I put the bad sensor back in the fan runs all the time again yet the unit heats?!?
no one has any insight or suggestions?
