Microwave displays PF or P0 after a power outage or when first plugged in; it may require a clock reset.

Safety: If you suspect wiring issues, consult an electrician.

Steps:

• 1. Reset the clock: Follow the user manual to set the time. If the microwave operates normally afterward, PF was just a notification.
• 2. Check the outlet: Plug another appliance into the same outlet to confirm stable power. Avoid using lightweight extension cords.
• 3. Inspect the power cord: Look for cuts, kinks, or burn marks. If damaged, the cord or filter board assembly should be replaced by a technician.
• 4. If PF appears frequently without outages: There may be an internal power supply issue (line filter board, control board). Have a technician inspect and test.
