Wine cooler not cooling at all; interior at room temperature; display and lights work but no cold air.

Safety first: Unplug the appliance before removing rear covers. Do not attempt to open the sealed refrigeration system yourself.

Steps:

• 1. Listen for compressor: With the unit plugged in, listen at the back. If the compressor is silent and not vibrating, it may not be receiving power or may be failed.
• 2. Check condenser temperature: Carefully feel the condenser coils (they should be warm when the compressor runs). If they remain cold, the compressor is not operating.
• 3. Basic electrical checks: Verify that the thermostat is not set to OFF and that no demo mode is active. Perform a power reset.
• 4. Visual inspection: Remove the rear lower cover and look for burnt wiring, loose connectors, or a tripped overload device.
• 5. Call a professional: If the compressor attempts to start and clicks off, or runs but no cooling occurs, a sealed system issue is likely. Only an F-gas certified technician should diagnose and repair refrigerant leaks, replace compressors, or open the sealed system.
