How to Fix / Troubleshooting
Safety first: Sealed system repairs require EPA-certified technicians and specialized tools. Do not attempt to open the sealed system yourself.
- Check door seal and loading: Ensure the door gasket seals fully and that the freezer is not overloaded or blocking air vents.
- Clean condenser coils: Unplug the unit and vacuum dust from the condenser coils and fan area to improve heat rejection.
- Inspect frost pattern: Remove the interior rear panel and observe the evaporator after 10–15 minutes of run time. A normal pattern is light frost across most of the coil. Frost only on a small section or no frost suggests a sealed system issue.
- Call a professional: If the frost pattern is abnormal and fans/compressor run, contact a qualified technician to check pressures, locate leaks, and recharge or replace components as needed.
