This genuine OEM Carrier flame sensor (LH680534) verifies burner flame on your GB3AAV060115AGJA gas furnace throughout every heating cycle. Using flame rectification, the sensor signals the control board that the burners lit successfully so the gas valve stays open; a dirty, corroded, or failed sensor leads to short cycling, no heat, or a furnace that ignites then shuts down within seconds. Manufactured to exact Carrier specifications, this direct-fit rod restores dependable, continuous furnace operation. Installation is easy for most homeowners and takes roughly 15-20 minutes - turn off power and gas, remove the single mounting screw, disconnect the lead, and install the new sensor. Confirm your model and part number before ordering. This part is in stock and ships same-day when your order is placed before 3PM CST, so you can get your heat back fast. Genuine OEM quality ensures a precise, long-lasting fit on your Carrier furnace.
This part is compatible with Carrier model GB3AAV060115AGJA.
