Wine cooler runs but does not get cold enough; temperature remains several degrees above setpoint in all zones.

Safety: Unplug the unit before cleaning coils or working near the compressor.

Steps to improve cooling:

• 1. Verify ambient temperature: Ensure the room temperature is within Gaggenau’s specified operating range (typically not above 32°C/90°F). Excessive heat reduces cooling capacity.
• 2. Clean condenser coils: Remove the front grille or rear panel and vacuum dust from the condenser. Use a soft brush to loosen stubborn dirt.
• 3. Check condenser fan: Confirm the fan runs whenever the compressor is on. Replace the fan motor if it is not running or is very weak.
• 4. Inspect door gaskets: Look for gaps, tears, or hardened seals. Close the door on a sheet of paper; if it pulls out easily, the gasket may not be sealing. Replace if necessary.
• 5. Avoid overloading and blocking airflow: Do not pack bottles tightly against the rear wall or air vents. Allow space for air circulation.
• 6. Monitor performance: After cleaning and adjustments, allow 24 hours for temperatures to stabilize and verify with an accurate thermometer.

Note: If cooling remains poor after these steps, a sealed system issue or sensor/control problem may be present and requires professional diagnosis.
