The Er IF error code on a Kenmore refrigerator (common on LG-platform Kenmore models) indicates a fault with the ice maker fan motor. The ice maker compartment fan circulates cold air to keep the ice maker at the correct temperature. When this fan fails or is obstructed, the ice maker cannot operate at optimal conditions.
Causes
- Ice buildup obstructing the ice maker fan blades
- Failed ice maker fan motor
- Wiring fault to the fan motor
Troubleshooting
- Check the ice maker compartment for excessive ice buildup. Defrost the freezer and ice maker area manually if ice has accumulated around the fan.
- After defrost and restart, check if the error clears.
- If Er IF persists, the fan motor requires professional replacement.
