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

Safety Warning: Sealed system work involves refrigerant and should only be performed by certified technicians. Do not attempt to cut or open refrigerant lines.

Homeowner checks:

• Verify operation: Confirm that the compressor and fans are running continuously but the cabinet does not cool after several hours.
• Check for frost pattern: If accessible, remove the interior panel and inspect the evaporator. A very small frost patch or no frost at all suggests a sealed system issue.
• Listen for unusual noises: A clicking compressor that never starts may indicate an electrical start issue rather than a sealed system problem.
• Inspect for oily residue: Look around tubing joints for oily spots, which can indicate a refrigerant leak.
• Call a professional: If the unit runs but does not cool and basic electrical components (fans, start relay) appear functional, contact a Whirlpool-authorized service provider for sealed system diagnosis and repair.

Note: In many compact wine coolers, sealed system repairs can approach or exceed replacement cost; discuss options with your technician.
