Why Replace the Flame Rod & Electrode?
Over time, flame rods accumulate oxidation and carbon deposits that reduce their ability to conduct the microamp flame signal back to the control board. Similarly, ignition electrodes can develop cracks in the ceramic insulator or erode at the tip, weakening the spark. Replacing both components together as a kit ensures a complete restoration of ignition system integrity.
