Overview
This OEM hot surface igniter (part 1171306) is the ignition component for the ICP / Tempstar / Heil RGS120HRCA0AAA gas furnace, supplied here with its matching wiring kit (part 1188370). On a call for heat, the furnace control board sends 120V to the igniter, which glows red-hot and ignites the gas at the burners. When an igniter ages, the silicon nitride element develops micro-cracks and hairline fractures that increase resistance until it can no longer reach ignition temperature. Typical failure symptoms are a furnace that clicks and tries to light but never fires, a glowing igniter that produces no flame, repeated lockouts after 2–3 ignition attempts, or no glow at all. Replacing a weak igniter is one of the most common no-heat repairs on this furnace platform.
