This OEM igniter electrode (part 1179966) generates the high-voltage spark that lights the burner on the ICP/Heil/Tempstar RGS240HFEA0AAAA gas furnace. On a call for heat the ignition control sends voltage to the electrode, which arcs across its gap to ignite the gas as it reaches the burner. The same electrode (or a paired sensing electrode) confirms a flame is present so the control keeps the gas valve open. Because the electrode tip sits directly in the burner flame, the ceramic insulator and metal rod degrade over time from heat cycling, cracking, carbon buildup, and erosion of the gap. A worn electrode produces weak or no spark, causing failed ignition, delayed ignition with a rollout puff, or short-cycling lockouts. Maintaining the correct gap and a clean, intact insulator is essential for reliable light-off.
