Possible Causes
Failed cooling fan motor, Blocked fan blades, Faulty fan speed sensor (tach), Loose fan wiring
How to Fix / Troubleshooting
Safety first: Disconnect from mains.
- Check airflow: Ensure external vents are not blocked. Clean dust and grease from intake and exhaust grilles.
- Inspect fan: Remove the outer cover and locate the main cooling fan. Check that the blades are not obstructed and spin freely.
- Test fan motor: Measure resistance across the motor terminals. An open circuit indicates a failed motor. Check for burnt smell or discoloration.
- Check wiring and sensor: Inspect the wiring harness and any attached tachometer sensor for damage or loose connections.
- Replace fan assembly: Install a new Zanussi-compatible cooling fan motor (and sensor if separate), ensuring correct orientation for airflow.
