Kenmore Refrigerator Er FS Error — Fan Short Circuit
The Er FS error code on Kenmore refrigerators indicates a short circuit or overcurrent condition detected in one of the internal fan circuits — either the evaporator fan (freezer) or the condenser fan. This protective error prevents a dangerous continuous short from damaging the main control board.
Which Fan is Affected?
Kenmore refrigerators typically have two internal fans: the evaporator fan motor (circulates cold air from the freezer into the fridge compartment) and the condenser fan (cools the compressor and condenser coils). The Er FS code can relate to either. Listen for which fan has gone quiet.
Troubleshooting
- Unplug the refrigerator for 5 minutes and reconnect — if the error returns immediately, a component is shorted.
- Listen for abnormal fan noise (grinding or no sound) when the compressor runs.
- Test each fan motor winding for resistance — a shorted winding (near-zero resistance) confirms motor failure.
Repair
Fan motor replacement is a straightforward repair that our technicians complete in a single visit. We test both fan motors and verify wiring harness integrity to prevent recurrence.
