Wine cooler runs (fans and compressor audible) but does not cool; interior remains at room temperature.

Safety: Sealed-system repairs involve refrigerant and must be performed by a licensed refrigeration technician. Do not cut or open refrigerant lines yourself.

• Check basic airflow: Confirm that the condenser fan is running and the condenser coil is clean. Poor airflow can mimic sealed-system issues.
• Feel the compressor and lines: With the unit running, carefully touch (briefly) the compressor and refrigerant lines. A normal system will have a warm discharge line and cool suction line. If everything is at room temperature, the system may be empty of refrigerant.
• Look for oil stains: Oil spots on tubing or around joints can indicate a refrigerant leak.
• Do not attempt DIY recharge: Aobosi systems are factory-charged and sealed. Recharging requires leak detection, evacuation, and precise charging by a professional.
• Contact service: Arrange for an authorized Aobosi or local refrigeration technician to evaluate and repair the sealed system.
