How to Fix / Troubleshooting
Safety first: Disconnect power before removing interior panels.
Steps:
- Check airflow: Place your hand near the air vents in the fridge compartment. Weak or no airflow while the unit is running suggests a fan issue.
- Access fan: Remove shelves and the rear interior panel of the fridge compartment to expose the fan assembly.
- Inspect for obstructions: Look for ice buildup, packaging, or debris interfering with the fan. Clear any obstructions carefully.
- Test fan movement: Spin the blades by hand. If stiff, noisy, or wobbly, replace the fan motor assembly.
- Check wiring: Verify the fan connector is fully seated and wires are intact.
After repair: Reassemble panels, restore power, and confirm that airflow has returned and the E12 code clears after a power reset.
