Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the freezer before moving or inspecting the rear components. Refrigerant work must be done by certified personnel.
- Check basic conditions: Ensure doors are sealing properly and the freezer is not overloaded with warm food.
- Inspect condenser temperature: After running for 15–20 minutes (technician only), the condenser should be warm to hot. If it is barely warm while the compressor runs, there may be a refrigerant issue.
- Look for oil stains: Oil around joints or tubing can indicate a refrigerant leak.
- Verify fan operation: Make sure any condenser fan is running and coils are clean.
- Call a professional: If airflow and seals are good but cooling is weak and E20 persists, a sealed system technician must check pressures, locate leaks, and recharge or repair the system.
Warning: Do not attempt to cut or open refrigerant lines yourself; this is hazardous and illegal in many regions without proper certification.
