Possible Causes

How to Fix / Troubleshooting
Safety: Unplug the unit. Refrigerant handling must be done by certified technicians.
- Visual inspection: Look for oily residue on tubing, evaporator, or around joints, which indicates a refrigerant leak.
- Do not attempt DIY sealed‑system repair: Specialized tools and certification are required to evacuate, repair, and recharge the system.
- Contact service: Arrange for a licensed refrigeration technician to locate and repair the leak, replace the filter‑drier, evacuate, and recharge with the correct refrigerant and charge specified by Summit.
- Consider replacement: For small wine coolers, sealed‑system repair may approach replacement cost.
