LG Refrigerator Error Code Er rF — Refrigerator Fan Motor Error
What this means
The Er rF error code indicates an abnormality in the refrigerator compartment fan motor. This fan circulates cold air throughout the refrigerator section. Common causes include frost buildup blocking the fan, a failed fan motor, or a wiring issue. Without this fan, the refrigerator section will not cool evenly and may warm up.
Alternate codes: rF
Step-by-step fix
3 stepsDefrost the refrigerator
Unplug the unit and remove all food and ice from the ice bin. Leave the doors open for at least 8 hours to allow all frost and ice to melt. Place towels in and around the unit to absorb water.
A hair dryer on low heat can speed up the defrosting process, but do not direct it at plastic parts.
Check door alignment and gaskets
After defrosting, verify the doors close properly and the gaskets seal tightly. Poor door sealing causes moisture to enter and frost to build up on the fan.
Restart and monitor
Plug the refrigerator back in. Remove any remaining moisture. Wait 24-48 hours for normal temperatures to establish.
When to call a professional
If the error returns after a full manual defrost, the fan motor itself has likely failed and needs professional replacement.
