If you mean how to turn on the fan on a Wolf range , it’s usually controlled by a fan switch/button near the oven control knob on GR series models, and some oven fans are part of the convection setting rather than a separate always-on switch.

Quick check

  • Look near the oven controls for a fan switch or fan toggle.
  • If your model has a convection oven, the fan may start when you set the oven to a convection mode rather than by itself.
  • If you’re trying to relight a pilot or restore heat, make sure the oven is off first and wait 5 minutes before following the lighting steps.

If the fan still will not run

  • Confirm the range has power and the correct oven mode is selected.
  • Check whether you mean the vent hood fan above the range; that is a separate appliance and uses the hood controls, not the range controls.
  • If you tell me your exact Wolf model number, I can give you the precise control location and steps.
