Protect and restore your GB1AAV060155ADJA furnace with this genuine OEM Carrier flame sensor (LH680016). The sensor confirms the burners have ignited on each cycle; without a valid flame signal the control board cuts gas within seconds, a vital safeguard against unburned gas accumulating in your home. A fouled, oxidized, or aged sensor is the leading cause of a furnace that lights for a few seconds then shuts down and short-cycles. This exact-fit replacement is made to Carrier's original specifications for the GB1AAV060155ADJA, with the right rod length, bracket, and flame-rectification output for a stable signal. Installation is among the simplest furnace fixes—about 10 to 15 minutes: power off, remove one mounting screw, disconnect the lead, and install the new sensor without touching the metal rod with bare hands. Replacing a degraded sensor rather than repeatedly cleaning it ends recurring lockouts for good. In stock and ships same-day when you order before 3PM CST, so steady heat comes back fast. Trust the exact part Carrier engineered for your furnace.
