Ventilation Hood Will Not Turn On or Off


  • Circuit breaker switch tripped off
  • Not plugged in
  • Incorrectly wired
  • Blower failure


  • Why did the Pro Ventilation or Cooktop (CT) Hood turn on automatically during cooking?
  • How does the ventilation hood turn on by itself?
  • Ventilation system will not turn on or off

Steps to Verify Issue:

If a Wolf Ventilation System will not turn on or off:

  1. Verify proper installation. Refer to the product Installation Guide for further information.
  2. If the product is installed properly:
    • Verify knob is not broken.
    • Reset at the circuit breaker.
    • Verify blower is plugged in. Blower plug is found inside the hood shell.
  3. Cooktop (CT) Wall, CT Island, CTE Low Profile, and all Pro Ventilation Hoods use a heat sentry feature.
    • This turns the ventilation hood on when heat is sensed and adjusts the blower speed automatically.
