Possible Causes
Partial refrigerant leak, Weak compressor valves, Partially blocked capillary tube, Condenser coil heavily clogged with dust
How to Fix / Troubleshooting
Safety first: Unplug the freezer before cleaning or accessing rear components.
What to do:
- Clean condenser: Remove rear lower panel and vacuum dust from condenser coil and fan. Ensure good airflow around the appliance.
- Check door seal: Inspect the door gasket for gaps or tears. Replace if it does not seal properly.
- Check frost pattern: Remove the interior rear panel and observe the evaporator after 20–30 minutes of operation. A healthy system should have even frost across most of the coil. If only a small section frosts, suspect a sealed-system issue.
- Professional service: For suspected refrigerant or compressor problems, contact a certified technician. These repairs require specialized tools and must comply with refrigerant regulations.
