It sends a microamp flame-rectification signal to the control board so the gas valve only stays open when combustion is verified; a dirty or degraded sensor results in short-cycling, lockouts, and frustrating no-heat calls. Built to exact factory specifications for the GB1AAV048111ACJA, it provides the correct rod resistance and a clean, stable signal that aftermarket sensors often can't deliver. Installation is easy and DIY-friendly: turn off power and gas, remove the single mounting screw, disconnect the wire lead, and reverse the steps — typically a 10-minute job with a nut driver. We recommend gently cleaning the sensor rod with fine emery cloth at each install. Restore safe, dependable heating with a part engineered specifically for your furnace rather than a universal substitute.
