Possible Causes
Failed DC evaporator fan motor, ice obstruction around fan blades, broken fan harness, faulty fan driver on main PCB
How to Fix / Troubleshooting
Safety: Unplug the freezer before accessing the evaporator area.
Steps:
- 1. Access fan: Remove baskets and the inner rear panel to expose the evaporator fan assembly.
- 2. Check for ice blockage: Inspect the fan blades and shroud for ice buildup. If present, allow a full manual defrost until all ice is gone. Do not force the fan to turn through ice.
- 3. Spin test: Gently spin the fan by hand. It should rotate freely without grinding or resistance. Stiff or noisy movement indicates a bad motor or bearing.
- 4. Wiring inspection: Check the fan motor connector and harness for loose pins or damage. Reseat the connector.
- 5. Voltage test (advanced): With power on and door switch held closed, a technician can measure DC voltage at the fan connector. Correct voltage with no rotation confirms a failed fan motor.
- 6. Replace fan motor: Install the correct Panasonic evaporator fan motor, transferring the fan blade if necessary and ensuring correct airflow direction.
