How to Fix Refrigerator Error

Verify household circuit breaker hasn’t tripped – reset if necessary.
Check GFCI outlet (if applicable) hasn’t tripped – press reset button.
Inspect power cord for damage or loose connection at wall outlet.
Plug refrigerator directly into wall outlet (remove extension cords).
Verify outlet provides stable 120V AC using multimeter (voltage sags can trigger PF).
Press CANCEL button to clear display if error persists after power restoration.
If PF occurs repeatedly without actual power loss, suspect loose neutral connection in house wiring – contact electrician.
Check main control board power terminal connections for looseness (requires removing rear access panel).
If PF occurs during compressor startup, suspect weak household circuit unable to handle inrush current – dedicated 15-20 amp circuit recommended.
Monitor voltage at outlet during compressor startup using recording multimeter to detect sags below 105V.

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
