Safety first: Disconnect power before accessing the fan. Beware of sharp metal edges.

Steps:

1. Listen for fan operation: With the door switch held closed (before unplugging), the fan should run when the compressor is on. If silent or intermittent, proceed.
2. Access the fan: Remove shelves/drawers and the rear interior panel of the affected compartment. Defrost any ice blocking the panel.
3. Inspect the fan: Check if ice or debris is blocking the blades. Spin the fan by hand; it should rotate freely without grinding.
4. Test the motor: Disconnect the fan connector and measure resistance across the motor terminals (for DC fans, you may see a few hundred ohms). An open circuit indicates a failed motor.
5. Check wiring: Inspect the harness from the fan to the PCB for cuts or loose plugs. Repair as needed.
6. Replace the fan motor: Unscrew or unclip the fan assembly, transfer the fan blade if separate, and install the new motor. Ensure the blade is correctly oriented and not rubbing on the shroud.
7. If motor and wiring are good: The main PCB fan driver may be defective. This requires PCB replacement and is best handled by a technician.
