How to Fix / Troubleshooting

Safety: Unplug the wine cooler before defrosting or accessing the evaporator.

Steps:

Manual defrost: Remove all bottles, unplug the unit, and leave the door open until all ice melts. Do not use sharp tools to chip ice.
Inspect door gasket: Check for gaps or tears that allow moist air in. Replace the door gasket if it does not seal properly.
Test defrost heater and sensor: After ice is cleared and panels removed, measure resistance of the defrost heater and defrost NTC sensor. Replace any open or shorted components.
Check control board: If heater and sensor are good, the defrost control circuit on the main PCB may be defective and require replacement.

Note: Regularly ensure the door is fully closed to minimize frost buildup.

Excessive frost or ice buildup on the back interior wall or around the evaporator; cooling gradually worsens.
