This genuine OEM Carrier flame sensor verifies that the burners in your GB1AAV048135AGJA furnace have ignited, telling the control board flame is present so it keeps the gas valve open safely. If no flame is detected, the board shuts the furnace down to prevent dangerous gas buildup. The hallmark of a dirty or worn flame sensor is a furnace that lights for several seconds and then shuts off, cycling over and over without sustained heat. Built to exact Carrier specifications, this sensor has the correct rod length and mounting for accurate flame rectification and dependable signaling. Replacement is very easy and perfect for DIY: cut power, remove the single mounting screw, unplug the wire, install the new sensor, and reconnect. Most jobs take just 10–15 minutes. A new sensor ends nagging short-cycle lockouts and restores steady, continuous heat. We keep this part in stock for immediate shipment. Order before 3PM CST and your flame sensor ships same-day, letting you fix the most common furnace fault and get warm again today.
