Possible Causes
Failed lower zone evaporator fan, Blocked air duct between zones, Faulty lower zone temperature sensor, Partial refrigerant restriction to lower evaporator
How to Fix / Troubleshooting
Safety: Unplug the unit before accessing internal components.
- Check setpoints: Confirm the lower zone is set to a cooler temperature than ambient and not accidentally turned off.
- Fan operation: Listen for airflow in the lower zone. If absent, access the lower evaporator fan and test/replace it.
- Inspect air ducts: Ensure vents between zones are not blocked by bottles or shelves.
- Sensor check: Test or replace the lower zone NTC sensor if the display shows incorrect or unstable temperatures.
- Sealed system: If the fan and sensor are good but the lower evaporator does not frost while the upper does, a sealed system restriction may exist and requires a refrigeration technician.
