Wine cooler runs but does not get cold enough; temperature stays above setpoint by 10°F or more.

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

Steps to improve insufficient cooling:

• 1. Check installation: Ensure the cooler has proper clearance on all sides and is not installed in a hot, enclosed cabinet without ventilation.
• 2. Clean condenser coils: Pull the unit away from the wall. Use a soft brush and vacuum to remove dust from the condenser coils at the back or underneath.
• 3. Verify condenser fan operation: With the rear cover removed and power restored, confirm that the condenser fan runs whenever the compressor is on. If not, test and replace the fan motor.
• 4. Inspect door gasket: Look for air leaks around the door. Replace a torn or hardened gasket to prevent warm air infiltration.
• 5. Evaluate sealed system: If coils are clean, fans work, and the compressor runs continuously but the unit still cannot reach temperature, a refrigerant leak or weak compressor is likely. This requires a licensed refrigeration technician for leak detection and repair.

Note: Overloading the cabinet with tightly packed bottles can also reduce cooling efficiency; leave space for air circulation.
