What HI Means
HI means a wine storage zone has been running above its set temperature longer than the unit's allowed threshold.
Common Causes of HI
- Door not sealing fully
- Unit installed without adequate ventilation clearance
- Sealed system problem reducing cooling capacity
🔧 One Safe Check You Can Try
Confirm the door is sealing fully and that the cabinet isn't placed somewhere with poor ventilation clearance, since restricted airflow around the unit can push zone temperatures up.
⚠ Why You Shouldn't Go Further Than That
- If door seal and clearance check out, diagnosing a sealed-system cause needs a technician.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
