This genuine OEM Carrier flame sensor (LH680534) is the safety component that confirms a burner flame is present after ignition on your Carrier GB1AAV060111ACJA gas furnace. It generates a microamp signal that tells the control board the burners have lit; when the sensor becomes coated or fails, the furnace will ignite then shut down on a flame-loss fault, often after several short-cycle attempts. Replacing it restores reliable, continuous heating and prevents nuisance lockouts. Precision-matched to the GB1AAV060111ACJA burner assembly for correct rod position and flame rectification. Installation is easy and typically takes under 20 minutes with a single screw and one push-on wire connector — a great DIY repair for handy homeowners or a quick fix for any HVAC technician. Always shut off power and gas before servicing. Using a true Carrier OEM sensor ensures correct material, length, and signal strength versus generic substitutes. In stock and ships same-day when you order before 3PM CST. Backed by our fitment guarantee for the GB1AAV060111ACJA furnace platform.
