What OVR-HT Means
This warning means the hood's electronics have detected excessive heat buildup inside the control housing, separate from the motor's own thermal protection.
Common Causes of OVR-HT
- Control electronics are failing and generating excess heat
- Ventilation slots on the hood body are blocked
- The range below is running unusually hot for an extended period
🔧 One Safe Check You Can Try
Check that nothing is blocking ventilation slots on the hood body itself, but don't continue operating the unit once this warning is showing.
⚠ Why You Shouldn't Go Further Than That
- Continuing to run a hood showing an overheat warning risks damaging the control board entirely.
- Opening the control housing to inspect the electronics directly is technician work.
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.
