Most likely causes

  1. Frozen or frost-locked fan blade
  2. Failed fresh food compartment fan motor
  3. Loose or damaged fan wiring connector
  4. Defrost problem letting frost build near the fan
Before you start — unplug the refrigerator before working on it. Mind sharp metal edges, and never open the sealed refrigerant system — compressor, sealed-system and refrigerant work must be left to a qualified technician.

Step-by-step fix

1Reset powerUnplug the unit or trip its breaker, wait about 5 minutes, then restore power to see if the fault clears.
2Thaw any iceIf the code persists, unplug the fridge and let the compartment defrost with the door open for up to a day before restarting.
3Clear ventsMake sure food is not blocking the interior air vents and the door closes and seals properly.
4Get serviceA returning Er rF usually means the fan motor or main board needs a technician to test and replace.

Still showing Er rF?

If you’ve worked through every step and Er rF keeps returning, an internal part likely needs testing and replacement. That’s a job for a qualified appliance technician, who can measure the suspect part against the service-manual spec before replacing it.
