About the High Limit Thermostat

If the microwave overheats, the high limit thermostat will trip to cut off voltage to the microwave. If the thermostat is shorted open, it may not allow voltage to reach the high voltage components which will prevent the microwave from working. To determine if the thermostat is at fault, use a multimeter to test it for electrical continuity. If the thermostat does not have continuity, and it cannot be reset, replace it.
