When to Replace

  • The furnace cycles on but the burner shuts off after a few seconds.
  • The furnace fails to produce heat or does not stay lit.
  • The ceramic insulator on the existing sensor is cracked or broken.
  • The metal rod is corroded, covered in carbon buildup, or physically damaged.

Installation Tips

  • Disconnect all electrical power to the furnace before beginning service.
  • Handle the new sensor by its ceramic base; avoid touching the metal rod with bare hands as skin oils can cause premature failure.
  • Ensure the single mounting screw is secure but not overtightened to avoid cracking the ceramic.
  • Position the sensor so the metal rod is properly enveloped by the burner flame during operation.
