The thermal fuse cuts off power to the microwave if the microwave overheats. To determine if the thermal fuse has blown, use a multimeter to test it for continuity. If the fuse doesn’t have continuity, replace it. The thermal fuse cannot be reset—if the fuse is blown, it must be replaced. (Caution: The microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. Due to the potential for electric shock, it is extremely dangerous to replace the electronic components in a microwave. Only a licensed technician should replace the thermal fuse.)

Sadly that is not the thermal fuse for your unit as I am unable to find that particular part being manufactured anymore but that is a visual aid for what the problem is. Again do not order that part because its not for your unit.

This is the manual for your particular unit. The only other part that it could be is the magnetron which unfortunately is pretty expensive.
