Wine cooler runs but does not reach set temperature; interior remains too warm.

Safety: Unplug the unit before removing panels. Refrigerant work must be done by a certified technician.

• Check temperature settings: Verify that the setpoint is correct for wine storage (typically 10–14°C) and that the unit is not in a demo or standby mode.
• Inspect door seal: Ensure the door gasket seals fully around the frame. Look for gaps, tears, or warped areas. Replace the gasket if it does not seal properly.
• Clean condenser: Remove rear panel and clean the condenser coil thoroughly. Poor heat rejection can mimic low refrigerant symptoms.
• Check condenser fan: Confirm that the fan runs with the compressor. Replace if not operating.
• Observe frost pattern: With the interior panel removed, run the unit briefly and observe the evaporator. A uniform light frost is normal; heavy frost only at the inlet or no frost at all suggests a sealed-system issue (leak, restriction, or weak compressor) that requires a professional refrigeration technician.
