Possible Causes
Failed evaporator fan in affected zone, Blocked air duct between zones, Separate evaporator or valve fault for that zone, Faulty temperature sensor for that zone
How to Fix / Troubleshooting
Safety: Unplug the unit before removing interior panels.
- Compare fans: Listen for fan operation in both zones. If one zone is silent, its fan may have failed.
- Access fan and ducts: Remove the rear interior panel of the warm zone to inspect the fan and air channels. Clear any obstructions.
- Test sensor: Swap the temperature sensors between zones (if identical and accessible) to see if the problem follows the sensor. If it does, replace the faulty sensor.
- Advanced faults: If the fan and sensor are good, the issue may be with a zone-specific evaporator or valve, which requires professional diagnosis.
