Quick Assessment
Answer to continue safely
Is it safe to keep using?
Maybe. After cooling, the hood should restart. If OVR-HT only occurs during very intensive cooking, reducing burner use or improving kitchen ventilation may help. Recurring OVR-HT indicates a mounting or design issue.
Can I reset the code?
Yes. Wait 15-20 minutes for the electronics to cool. OVR-HT clears automatically once temperature drops to safe levels.
When to stop immediately?
Stop if you notice: If OVR-HT triggers during normal cooking, If the hood housing is too hot to touch comfortably.

If the hood is too low, reinstallation at the correct height is required.
