Wine cooler runs constantly but only cools slightly, cannot reach set temperature

Safety first: Unplug the unit before cleaning or accessing the rear compartment.

Steps:

• Clean condenser: Use a soft brush or vacuum to remove dust from the rear condenser grille or coil. Improved airflow can significantly enhance cooling.
• Check condenser fan: If your Cavin model has a condenser fan near the compressor, verify it runs when the compressor is on. Replace if not spinning or noisy.
• Inspect door gasket: Look for gaps, tears, or hardened sections of the gasket. Perform the paper test around the door perimeter.
• Ambient temperature: Ensure the cooler is not installed in a very hot or enclosed space without ventilation.

Professional service: If the condenser is clean, fans work, and the door seals well but cooling is still weak, a refrigerant leak or internal restriction is likely. This requires a certified technician to locate the leak, repair it, and recharge the system.
