Compressor and fans run, but there is no frost on the evaporator and no cooling effect.
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Do not attempt to open the sealed refrigeration system without proper certification and tools. Refrigerant handling is regulated.
Diagnostic steps (visual only):
- 1. Confirm operation: Verify that the compressor is running (warm and vibrating) and the condenser is warm.
- 2. Inspect evaporator: Remove the interior rear panel and observe the evaporator coil after 10–20 minutes of run time. No frost or only a tiny patch of frost suggests a sealed system issue.
- 3. Check for oily residue: Look for oil stains on tubing joints, which can indicate a refrigerant leak.
Action: Sealed system repairs (locating leaks, replacing the compressor, recharging refrigerant) must be performed by an EPA-certified refrigeration technician. In many cases, replacement of the entire wine cooler may be more economical.
