Wine cooler not cooling at all; interior is at room temperature, though lights and display work.

Safety: Do not attempt to open the sealed refrigeration system yourself. High-pressure refrigerant work must be done by a certified technician. Unplug the unit before any internal inspection.

• Check basic operation: Listen for compressor and fan operation when the unit is switched on and set to a cold temperature. If both are silent, suspect electrical/control issues rather than sealed system.
• Inspect evaporator for ice: Remove the interior rear panel. If the evaporator is a solid block of ice, allow a full manual defrost (24 hours with door open) and then restart. If cooling returns only briefly, the defrost system needs repair.
• Check condenser temperature: Carefully feel the condenser coil at the back (when running). If it remains completely cold while the compressor is running, there may be a refrigerant issue or failed compressor.
• Look for oil stains: Oil spots on tubing or joints can indicate a refrigerant leak.
• Call a professional: For suspected refrigerant leaks, blocked capillary, or compressor failure, contact an authorized Balay service technician for leak detection, recharging, or compressor replacement.
