Problem: Power failure detected – voltage interruption >2 seconds causing control board reset
How to Fix Refrigerator Error
- Press CANCEL button to clear display.
- Verify household circuit breaker hasn’t tripped – reset if needed.
- Check power cord connection at wall outlet and refrigerator terminal block.
- Test outlet voltage: must be 110-125VAC. Low voltage (<105V) can trigger PF code.
- Inspect main control board for blown thermal fuse (small white component near power input) – replace if open circuit.
- If PF recurs frequently without actual outages, suspect failing main control board W10868991 with unstable power regulation circuit.
- Note: PF is informational only – refrigerator will resume normal operation after power restoration unless underlying electrical fault exists.
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
