Microwave displays PF (Power Failure) and may beep; clock may reset.

Safety: Ensure your hands are dry when working with electrical outlets.

• Reset clock: Press Clear/Off and then set the clock per the user manual. If PF does not return, no further action is needed.
• Check outlet: Verify the microwave plug is fully inserted. Test the outlet with another appliance to confirm power.
• Inspect breaker: Check your home's breaker panel for a tripped breaker and reset if necessary.
• Avoid shared circuits: If PF recurs frequently, move the microwave to a dedicated circuit or have an electrician inspect the wiring.

If PF appears without any actual power interruption, the control board may be failing and should be evaluated by a technician.
