Wine Enthusiast wine cooler makes a gurgling or hissing sound and cooling performance is poor.

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

• Confirm normal sounds: Some mild gurgling is normal as refrigerant flows. However, loud, continuous gurgling combined with poor cooling suggests a problem.
• Check for oily residue: Inspect tubing and joints for oily spots, which can indicate a refrigerant leak.
• Verify condenser and fan condition: Ensure coils are clean and fans are working to rule out airflow issues.
• Monitor temperatures: If the unit cannot reach set temperature despite good airflow and long run times, a sealed system issue is likely.

Sealed system diagnosis and repair (leak check, evacuation, recharge, or compressor replacement) must be performed by an EPA-certified refrigeration technician.
