Wine cooler not cooling; compressor runs but there is no noticeable temperature drop inside.

Safety: Do not attempt to cut or open refrigerant lines yourself. Refrigerant handling requires certified technicians.

Diagnostic steps:

• Check compressor and condenser: With the unit running, feel the condenser coil at the back. It should be warm. If the compressor is hot but the condenser is barely warm, suspect a sealed-system issue.
• Inspect for oil stains: Look for oily residue on tubing, joints, or around the evaporator area, which can indicate a refrigerant leak.
• Observe frost pattern: If you can see the evaporator, a healthy system will show even frost across most of the coil. A small patch of frost or no frost at all suggests low charge or restriction.
• Rule out airflow issues: Ensure both evaporator and condenser fans are operating and that filters/grilles are not blocked.

Action: Sealed-system repairs (leak detection, evacuation, recharging, compressor replacement) must be performed by an EPA-certified refrigeration technician. Contact Haier service or a qualified local technician for further diagnosis and repair.
