The PF display on a Kenmore microwave indicates a power failure occurred while the microwave was operating or on standby. This is an informational status, not an error requiring repair.
What To Do
- Press STOP/CLEAR to dismiss the PF notification.
- Reset the clock using the CLOCK button and entering the correct time.
- If PF appears without any known power outage, check that the outlet and breaker are functioning correctly and the microwave is not on a shared circuit that trips under load.
