Wine cooler runs constantly but does not get cold enough; temperature is only slightly below room temperature.

Safety: Do not attempt to open the sealed refrigeration system yourself. Refrigerant handling requires certification.

Basic checks:

• 1. Confirm door seal: Ensure the door gasket seals tightly all around. Replace if torn or deformed.
• 2. Clean condenser: Remove rear panel and clean condenser coils thoroughly to improve heat rejection.
• 3. Check for frost pattern: With the rear interior panel removed, observe the evaporator after 15–20 minutes of run time. A healthy system will frost evenly across most of the coil. Frost only at the inlet or no frost at all suggests a sealed system issue.

Professional repair required: If airflow and seals are good but cooling is still weak, a certified technician must check for leaks, restrictions, or a failing compressor. This typically involves specialized tools and may not be economical on older units.
