Frigidaire Microwave Error Code PF — Power Failure / Voltage Interruption
What this means
The PF error code on Frigidaire microwaves indicates a power interruption occurred, either during a cooking cycle or while the microwave was on standby. This is an informational code — not a malfunction. It tells you power was lost and the clock/settings may need to be reset. Common causes include power outages, tripped breakers, loose plugs, or shared circuits with high-draw appliances.
Step-by-step fix
3 stepsClear the error and reset the clock
Press Cancel/Clear to dismiss the PF code. Reset the clock to the current time. The microwave should be ready to use normally.
If you were cooking when the power was lost, check your food — it may need to be reheated or the cycle restarted.
Check the power supply
Verify the microwave plug is securely in the outlet. Check the circuit breaker — if it's tripped, reset it. If the microwave is on a shared circuit with the dishwasher or garbage disposal, running them simultaneously can trip the breaker.
Over-the-range microwaves should ideally be on a dedicated 20-amp circuit for reliable operation.
Prevent future power interruptions
If PF appears frequently, consider a surge protector or having an electrician check the circuit for loose connections. Ensure no other high-draw appliances share the same circuit.
A UPS (uninterruptible power supply) can prevent brief outages from affecting the microwave, though it's usually not necessary for most households.
When to call a professional
If PF appears repeatedly without known power outages, have an electrician inspect the dedicated circuit for loose wiring, a failing breaker, or voltage fluctuation issues.
