How to Fix / Troubleshooting
Safety: Unplug the appliance before servicing.
- Check airflow: Place your hand near the freezer vents with the door closed for a few minutes (before unplugging). Weak or no airflow suggests fan issues.
- Inspect for frost: Remove freezer rear panel and inspect the evaporator and fan area for heavy frost. If the coil is a solid block of ice, defrost the unit and check the defrost system.
- Fan motor test: With power off, check that the fan spins freely. Replace the fan motor if it is seized or noisy.
- Harness and connector: Verify the fan connector is tight and wires are not broken or pinched.
- Control board: If the fan does not receive voltage when commanded on, the main PCB may be defective and should be replaced by a qualified technician.
