This genuine OEM hot surface igniter (factory part number 1171306, IGNITOR) for the ICP / Tempstar / Heil RGS150LTCB0AAAA is paired with its matching wiring harness kit (1188370, WIRING KIT IGNITER) for a complete, clean replacement. On a call for heat, the control board sends voltage to the igniter, which glows red-hot and lights the burners. The igniter element is brittle and degrades with every heating cycle until it cracks or no longer reaches ignition temperature — the most common reason a furnace blows cold air or short-cycles on a failed ignition. Including the wiring kit ensures fresh connectors and leads, eliminating high-resistance terminals that prematurely kill the new igniter.
