How to Reset a LG Refrigerator
Power-cycle at the breaker or plug for 60 seconds; allow hours for temperatures to stabilize before re-judging.
Reset Steps
- 1
Unplug the refrigerator for 60 seconds, then restore power.
- 2
Expect a compressor restart delay of several minutes (normal).
- 3
Re-check after 2–4 hours of run time — a code that returns indicates a real fault.
💡 Good to know: After defrosting an iced evaporator with a power-off thaw (24–48h with doors open and towels down), the fan codes usually stay away only if the root defrost fault is also fixed.
If the Code Comes Back
A code that returns after a reset means the underlying fault is still present. Look up your exact code for its causes and step-by-step fix:
Er FF Freezer fan error — fan motor not operating Er dH Defrost heater error — defrost cycle not completing Er CF Condenser fan motor error Er FS Freezer temperature sensor error Er IS Ice maker sensor failure Er IF Ice maker fan error Er CO Communication error — main board to sub-board dS Defrost sensor open circuit
Frequently Asked Questions
Why does my LG fridge show Er rF after a power outage? +
The fridge fan may be temporarily iced or the controller flagged a stall during the outage. Power-cycle 60 seconds and watch for 2–4 hours. If Er rF returns, the evaporator fan or its icing problem needs attention.
