The F9 error code indicates the microwave is not furnishing high voltage to cook.

This problem can be caused by a bad control board, a bad inverter board, a bad magnetron, or a broken wire to one of these components.

Microwaves generate around 40,000 volts when cooking. Voltage can be stored in capacitors and can deliver an electrical shock when the microwave is unplugged.

I recommend you go to


and get a Sears technician to diagnose and repair the microwave.
