Possible Causes
Failed evaporator fan in one zone, Blocked air duct between zones, Faulty zone sensor, Partial refrigerant restriction affecting one evaporator
How to Fix / Troubleshooting
Safety: Unplug the cabinet before opening interior panels.
- Identify affected zone: Compare actual bottle temperatures in both zones.
- Check zone fan: Listen and visually confirm fan operation in the warm zone. Replace the fan motor if not running.
- Inspect air ducts: Ensure vents between zones are not blocked by shelves or bottles.
- Test zone sensor: Measure resistance of the NTC sensor in the warm zone and compare to the working zone. Replace if readings differ significantly.
- Sealed system: If fans and sensors are good but one evaporator remains warm, a sealed-system issue may exist and requires a professional technician.
