Door left open for extended period, Failed door gasket causing warm air ingress, Partial loss of refrigerant charge, Weak compressor
How to Fix / Troubleshooting
Safety first: No immediate electrical hazard, but avoid using sharp tools on ice or tubing.
- Ensure door closure: Verify the door closes fully and the seal contacts the cabinet all around. Adjust leveling feet if needed.
- Check gasket condition: Inspect for tears, warping, or hardened sections. Replace if not sealing properly.
- Reduce load and improve airflow: Avoid overpacking. Leave space around vents and along the back wall.
- Monitor temperature: After correcting door and load issues, allow 12–24 hours. If AL01 persists and the compressor runs constantly with poor cooling, a sealed system issue (refrigerant/compressor) is likely and requires a professional technician.
