Dual zone wine cooler one zone not cooling
One zone of a dual-zone cooler works, the other does not.
Symptoms
One compartment maintains temperature while the other stays warm. The display may show normal set points for both.
Likely causes
Failed zone damper, faulty zone-specific sensor, failed zone fan, or a control board issue affecting one zone only.
What you can safely check
Confirm both set points are correct. Check that nothing is blocking airflow between zones. Note which zone is affected.
When to call a professional
If one zone fails while the other works, the damper, sensor or fan for that zone has failed. This requires specialist diagnosis of the dual-zone system.
Our repair process
We test the affected zone's damper, fan and sensor independently, identify the failed component, repair or replace it, and verify both zones reach and hold their set temperatures.
Parts that may be involved
Zone damper, zone fan motor, zone temperature sensor, control board.
Safety note
Refrigeration systems contain pressurised gas and live electrical components. Do not attempt to open the sealed system, handle refrigerant, or bypass safety controls. For any fault beyond the safe checks above, book a specialist technician.
