Possible Causes
Failed upper zone evaporator fan, Blocked upper air duct, Faulty upper zone temperature sensor, Control board not energizing upper zone circuit
How to Fix / Troubleshooting
Safety: Disconnect power before accessing the upper zone fan or sensors.
Steps:
- Check vents: Ensure upper vents are not blocked by bottles or shelves.
- Access upper fan: Remove upper shelves and internal panel to reach the fan. Check for ice or obstructions.
- Test fan and sensor: As with the lower zone, verify fan operation and sensor resistance. Replace any faulty components with Zanussi-compatible parts.
- Inspect wiring: Check the harness from the upper zone to the main PCB for damage or loose connections.
Action: If components test good but the upper zone still does not cool, the control board may have a failed channel and require replacement.
