The Er FF error code on a Kenmore refrigerator indicates a failure of the freezer evaporator fan motor. This fan circulates cold air from the evaporator coils throughout the freezer and refrigerator compartments. A failed evaporator fan will cause both sections to warm up, putting food safety at risk.
Causes
- Failed evaporator fan motor
- Ice buildup blocking the fan blades
- Wiring fault to the fan motor
- Control board not sending power to the fan
Troubleshooting
- Listen for the fan — it should be audible when the refrigerator is running. Silence from the freezer compartment fan is a strong indicator of failure.
- Manually defrost the freezer and check if the fan spins freely by hand after defrost.
- If the fan does not spin freely or the motor makes unusual sounds, it requires professional replacement.
