Answer to continue safely

Is it safe to keep using?

Maybe. The compressor still cools, but without fan circulation some areas will be too warm and others too cold. Use short-term only.

Can I reset the code?

Yes. Yes — clear obstructions or defrost, then reset. If the motor has failed, the code will return.

When to stop immediately?

Stop if you notice: Fan makes grinding or scraping noises, Temperatures rising in multiple areas.

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Check for Obstructions

    Open the fridge and look near the fan vent (usually the rear wall). Remove any food items blocking it.

    Don't pack food directly against the rear wall.

  2. 2

    Check for Ice Buildup

    Look for frost or ice around the fan area. If present, defrost by turning off the fridge for 24 hours.

    Place towels under the fridge to catch melt water.

  3. 3

    Listen for Fan

    After clearing obstructions and resetting, listen for the fan. It should start within a few minutes of closing the door.

    The fan often stops when the door is open — press the door switch to simulate a closed door.

  4. 4

    Power Reset

    Turn off at mains for 5 minutes.

    The fan motor controller may restart.
