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.

  1. 1

    Let it cool and check mounting height

    Turn off the hood and cooktop. Wait 15-20 minutes. Check that the hood is mounted at the recommended height above the cooktop (typically 24-30 inches for gas, 20-24 inches for electric).

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

    Tools required
  2. 2

    Clean internal grease buildup

    Remove filters and clean any grease accumulation inside the hood body that may be insulating electronics.

    Annual deep cleaning of the hood interior prevents heat-trapping grease layers.

    Tools required

When to Call a Professional

Contact a qualified technician if:

  • Hood is mounted below minimum recommended height
  • OVR-HT triggers during moderate cooking intensity
  • Internal electronics show heat discoloration
