This OEM Carrier flame sensor (LH680534) verifies burner ignition on your GB1AAV060155ABJA furnace, sending the microamp flame-rectification signal that tells the control board to keep the gas valve open. When this sensor gets coated in residue or fails, your furnace will light and then shut off within seconds, repeating until it locks out — a classic short-cycle no-heat symptom. Designed as a direct-fit replacement for the GB1AAV060155ABJA, this genuine part delivers the precise rod placement and signal range your system requires, something universal sensors frequently miss. Installation is easy and takes under 15 minutes with one screwdriver: power down, unscrew the sensor at the burner assembly, disconnect the lead, and install the replacement. Choosing the authentic Carrier component ensures dependable flame proving and eliminates nuisance lockouts. Genuine OEM quality for seasons of reliable heat. In stock and ready to ship — orders placed before 3PM CST ship same-day so you can get warm fast.
