Microwave display shows PF and beeps after a power interruption; clock may be reset.

Safety: Ensure your hands are dry when handling the plug or breaker.

Steps:

• Confirm power: Check that the outlet has power by plugging in another device. Reset any tripped breakers.
• Secure plug: Make sure the microwave plug is fully inserted into the outlet.
• Clear PF: Press STOP/CLEAR, then reset the clock according to the user manual.
• Avoid shared heavy loads: Do not run the microwave on the same circuit as large appliances that may cause voltage drops.

If PF appears frequently without known outages, have an electrician check the circuit and consider having the microwave inspected for internal power supply issues.
