Possible Causes
Prolonged power outage, Door left open, Cooling system failure, Blocked condenser or evaporator airflow
How to Fix / Troubleshooting
Safety: Unplug the unit before cleaning coils or accessing fans.
Steps:
- Check door and load: Ensure the door is fully closing and not overloaded with bottles preventing seal contact.
- Allow recovery: After a power outage or door left open, it can take several hours to pull down temperature. Monitor for improvement.
- Inspect condenser and fans: Clean condenser coils and verify both condenser and evaporator fans are running when the compressor is on.
- Check for error codes: If Hi is accompanied by other codes (E1–E9, H1), troubleshoot those specific faults.
If Hi persists and the unit does not cool, a sealed system or compressor issue may be present and requires a professional technician.
