Possible Causes
Failed lower zone evaporator fan, Blocked air duct between zones, Faulty lower zone sensor, Partial refrigerant restriction to lower circuit
How to Fix / Troubleshooting
Safety: Unplug the dual-zone cooler before opening interior panels.
- Check airflow: Ensure vents between zones are not blocked by bottles or shelves.
- Inspect lower zone fan: Remove the lower rear interior panel and verify the fan runs when cooling is demanded. Replace the Blastcool lower zone evaporator fan motor if not.
- Test lower zone sensor: Inspect and test the lower zone NTC sensor; replace if misreading.
If fans and sensors are good but the lower zone still does not cool, a sealed system issue specific to that circuit may exist and requires a technician.
