  • Unfasten the Attachment Bolt: Reach for the flame sensor. If you are unsure of its look, it has the appearance of a white pole with its end bearing a metal point. It is located on the furnace’s bounding assembly’s exterior. Unfasten the screws and keep them in a place within your attention.
  • Pull Back: Withdraw the sensor from its original position and see through it. Check for any impediment. Being a technical matter, call a technician who can make the task easy for you, such as from furnace replacement in Portland.
