Possible Causes
Freezer door left open, Excessive frost blocking evaporator, Failed evaporator fan, Low refrigerant or compressor failure
How to Fix / Troubleshooting
Safety First: Unplug the refrigerator before removing any interior panels.
Steps:
- Check door seal: Ensure the freezer door closes tightly and the gasket is intact. Remove items that interfere with closure.
- Look for frost buildup: If you see heavy frost on the back freezer wall, the defrost system may be failing. Manually defrost by unplugging the unit and leaving doors open for several hours.
- Verify fan operation: After defrosting and reassembling, listen for the evaporator fan when the compressor is running. No fan sound indicates a fan or control issue.
- Monitor temperature: Allow 12–24 hours after defrosting to see if the freezer reaches the set temperature.
- Seek service: If H2 persists and the compressor runs continuously without adequate cooling, a sealed system problem is likely and requires a qualified technician.
