Wine cooler runs continuously and is too warm; compressor and fans are on almost all the time but set temperature is never reached.

Safety: Unplug the unit before cleaning or accessing rear components.

Steps:

• Clean condenser coils: Remove the rear lower panel and vacuum or brush dust from the condenser coils and fan blades. Improved airflow can significantly restore cooling performance.
• Check door gasket: Inspect the door seal for gaps or tears that allow warm air in. Replace the door gasket if it does not seal all around.
• Verify ambient temperature: Ensure the cooler is not installed in a very hot room or near heat sources, which can reduce cooling capacity.
• Monitor evaporator frost pattern: With the interior panel removed (unit running), a healthy system will show even frost across most of the evaporator. Frost only on a small section often indicates low refrigerant or a weak compressor.

Service recommendation: If cleaning and sealing do not resolve the issue and the frost pattern is abnormal, a sealed system technician should check for leaks and compressor performance.
