Possible Causes
How to Fix / Troubleshooting
Immediate checks:
- Verify the freezer door closes fully and the gasket is clean and undamaged.
- Look for heavy frost on the back wall; if present, the defrost system may be failing.
- Reduce large warm loads and allow time for temperature to recover.
Manual defrost (if frosted): Unplug the unit and leave doors open for 12–24 hours to clear ice, then restart.
Monitor: If H2 returns despite good sealing and no frost, the freezer sensor or control board may need professional diagnosis.
