This genuine OEM Carrier flame sensor confirms successful burner ignition on your GB3AAV036050ADJA gas furnace. Through flame rectification it passes a small microamp current to the control board; the moment that signal is lost, the board shuts the gas valve to keep unburned fuel from building up. A flame sensor fouled with oxidation or soot is the leading cause of a furnace that ignites, burns briefly, then drops out and tries again—short-cycling and eventual hard lockout. This rod is manufactured to the exact length, mounting bracket, and terminal spec of the GB3AAV036050ADJA so it seats in the factory position with no adjustment. The replacement is easy, about 10-15 minutes, using just a screwdriver or nut driver—a great first-time DIY furnace repair. Always shut off power at the disconnect before servicing. Bring back safe, steady heat with a true OEM sensor instead of a generic stand-in. In stock and ships same-day when your order is placed before 3PM CST.
