Visual Inspection
  • Power OFF your cooking device. Make sure your device is not hot.
  • Check all of the wire connections for visual damage. Check the fan, controller, and switch connections.
  • Check the controller for visual damage or water penetration. Water can damage your controller.
  • Check the fan for visual damage. Are there any cracks or damages in the fan or fan housing?
  • Check for debris in fan. You may need to remove the fan cover to remove any debris that has gotten into the fan. To remove the fan cover, remove the 4 screws in the corners of the fan shroud.
  • Check the switches for visual damage.
  • If any components have failed visual inspection, they should be replaced. Contact Masterbuilt Customer Service.
