Safety first: Unplug the unit before touching the compressor area. Refrigerant system work must be done by a licensed technician.

Check basic items: Verify the unit is powered, the control is set to cool, and the door is closing properly.
Compressor check: Remove the rear lower panel and plug the unit back in briefly. Listen for the compressor starting. If it is silent, hums then clicks, or is extremely hot, suspect a start component or compressor issue.
Start relay/overload: With power disconnected, remove and inspect the start relay and overload protector. Replace them with NEEDONE-compatible parts if they show signs of failure.
Condenser temperature: If the compressor runs but the condenser coil stays cool and no cooling occurs inside, the sealed system may be compromised.
Professional service: Sealed system repairs (compressor, refrigerant leaks) require specialized tools and certification. Contact a refrigeration technician for diagnosis and repair.

Wine cooler runs but does not cool; interior stays at room temperature.
