Frigidaire PF Error Code — What It Means
PF stands for Power Failure on your Frigidaire refrigerator. The control board detected that power was interrupted and then restored. This can happen during a utility outage, a voltage surge, a brownout, or even a brief flicker in your home’s electrical supply. On many models you will also see a Hi Temp alarm if the outage was long enough for the cabinet temperature to rise above safe thresholds. The refrigerator is alerting you to check food safety and acknowledge the event.
Common Causes
- Actual power outage or utility flicker A brief outage, brownout, or voltage surge from the utility is the most common cause of the PF code.
- Tripped or unstable circuit breaker A breaker that has tripped or is cycling on and off can create intermittent power loss and trigger the alarm.
- Loose power cord or poor receptacle contact A plug that is not fully seated or an outlet with worn contacts can cause repeated PF events without a house-wide outage.
- Wiring connection fault in the branch circuit Loose connections at the outlet, junction box, or breaker panel can interrupt line voltage to the refrigerator.
- Main control board or internal power supply fault If PF repeats with no real outage and the supply circuit is sound, the control board may be detecting false interruptions or failing internally.
Step-by-Step Fix
- {‘step’: ‘Verify whether a real power interruption occurred. Ask whether lights flickered, clocks reset, or other devices lost power at the same time the refrigerator showed PF.’}
- {‘step’: ‘Press the Alarm Reset button on the control panel to clear the PF code and any accompanying Hi Temp alarm after power is restored.’}
- {‘step’: ‘Check the circuit breaker at your electrical panel and reset it fully by switching it all the way off and then back on. If the breaker trips again immediately, stop and investigate the electrical supply before proceeding.’}
- {‘step’: ‘Inspect the power cord and receptacle. Unplug the refrigerator, examine the plug blades for burn marks or corrosion, confirm the outlet is tight and not loose in the wall, and plug the cord back in firmly.’}
- {‘step’: ‘Power-cycle the refrigerator by unplugging it or switching off the breaker for five minutes, then restore power and observe whether the PF code returns.’}
- {‘step’: ‘Monitor for recurrence. If PF appears again without any outage or circuit issue, suspect the main control board and prepare for diagnostic testing or replacement.’}
- {‘step’: ‘Check cabinet temperature if a Hi Temp alarm is also displayed. Discard any perishable food that has been above 40 °F for more than two hours, and confirm the unit cools back to normal before clearing the complaint.’}
Parts Often Needed
| Part | Notes |
|---|---|
| Main control board (electronic control) | Amazon | Replace if PF recurs with no real outage and the supply circuit is verified sound. |
| Power cord and plug assembly | Amazon | Replace if the cord shows damage, burn marks, or corroded blades that prevent solid contact. |
When to Call a Pro
Call a licensed electrician if your breaker trips repeatedly, if you find signs of overheating at the outlet or breaker, or if you are uncomfortable working inside your electrical panel. Call an appliance technician if the PF code returns after you have confirmed stable power and completed a control reset, since recurring false alarms usually point to a failing main control board that requires diagnostic tools and part replacement.
