How to Fix / Troubleshooting

Safety first: Unplug the unit before defrosting or accessing the evaporator. Do not use sharp tools to remove ice.

Step 1 – Manual defrost: Empty the cabinet, unplug the cooler, and leave the door open until all ice melts. Place towels to catch water.
Step 2 – Inspect gasket and door use: Check the door gasket for gaps or tears and replace if needed. Encourage shorter door openings to reduce moisture entry.
Step 3 – Test defrost components: After defrosting, access the evaporator and test the defrost heater and defrost thermistor for continuity and proper resistance. Replace any failed components with Café-compatible parts.
Step 4 – Check control board: If heater and sensor are good, the main control board may not be initiating defrost cycles and may need replacement.

Reassemble and monitor for several weeks. Recurring heavy frost indicates an unresolved defrost or air leak issue.

Excessive frost or ice buildup on the back wall or around the evaporator inside the wine cooler.
