This genuine OEM Carrier flame sensor is the safety component that confirms your burner has ignited on the GB3AAV036050AFJA gas furnace. It generates a small microamp signal through flame rectification; when the control board no longer detects that signal it shuts off the gas valve to prevent a dangerous fuel buildup. A dirty, corroded, or cracked flame sensor is the single most common cause of a furnace that lights briefly then shuts down on short-cycle lockout. This rod is engineered to the exact length, mounting bracket, and terminal spec of the GB3AAV036050AFJA, so it drops straight into the original location without modification. Installation is easy and typically takes 10-15 minutes with a single screwdriver and a nut driver—a confident DIY homeowner can complete it, no special tools required. Always cut power at the disconnect before servicing. Restore reliable, safe heating with a true OEM part instead of a generic substitute. In stock and ships same-day when your order is placed before 3PM CST.
