Whirlpool Refrigerator Error Code FAN ER — Evaporator or Condenser Fan Failure
What this means
The FAN ER error code on Whirlpool refrigerators indicates one of the fan motors — either the evaporator fan (inside the freezer) or the condenser fan (at the rear bottom) — has stopped running or is running below the expected RPM. Without proper fan operation, the refrigerator cannot circulate cold air effectively, leading to uneven or insufficient cooling.
Alternate codes: FANER
Step-by-step fix
3 stepsIdentify which fan is affected
Open the freezer and listen for the evaporator fan. It should run when the door is closed (press the door switch to simulate a closed door). Then check the condenser fan at the rear bottom of the unit — it should run whenever the compressor runs.
If neither fan is running, the issue may be the main control board rather than the fans themselves.
Check for obstructions
For the evaporator fan, remove the rear panel inside the freezer and check for ice buildup around the fan blades. For the condenser fan, pull the refrigerator away from the wall and check for debris, dust, or objects blocking the fan blades.
Heavy frost on the evaporator fan indicates a defrost system problem in addition to the fan issue.
Test and replace the failed fan motor
Unplug the refrigerator. Disconnect the fan motor wires and test with a multimeter. The motor should show some resistance (not open). If the motor is open or seized, replace it. Remove the mounting screws, transfer the fan blade to the new motor, and reinstall.
Try spinning the fan blade by hand first — if it spins freely, the motor may still be electrically failed. If it is stiff, bearings are seized.
When to call a professional
If both fans are running correctly but the code persists, the main control board's fan control circuit may be defective. A technician can verify with diagnostic mode.
