Possible Causes
Partial refrigerant leak in sealed system, Blocked capillary tube or filter drier, Weak compressor, Severely frosted evaporator reducing heat transfer
How to Fix / Troubleshooting
Safety: Unplug the cooler before any inspection. Sealed system work involves high pressure and refrigerant and must be done by certified technicians.
- Check for frost pattern: Remove the interior back panel and observe the evaporator after 10–15 minutes of operation. A normal pattern is even frost across most of the coil. Frost only at the inlet or no frost suggests a sealed system problem.
- Inspect for oil stains: Look around tubing joints and the compressor area for oily residue, which can indicate a refrigerant leak.
- Verify door sealing: Ensure the door gasket seals fully and the door is not being left open, which can mimic poor cooling.
- Call a professional: If a sealed system fault is suspected, contact a licensed refrigeration technician to check pressures, locate leaks, and recharge or replace components as needed.
