Microwave displays PF or "Power Failure" and beeps after an outage or brief power loss.

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

Reset and basic checks:

• Press STOP/CLEAR to clear the PF message, then reset the clock.
• If PF appears frequently, plug another appliance into the same outlet to check for intermittent power loss.
• Inspect the microwave's power cord for cuts, kinks, or burn marks. Do not use the unit if the cord is damaged.
• Avoid using extension cords or power strips; plug the microwave directly into a properly grounded outlet.

Internal check (advanced):

• If PF occurs without any household power issues, an internal line fuse or connection may be loose. This should be inspected and repaired by a qualified technician.
