Overview

This OEM hot surface igniter (part 1171306) plus matching igniter wiring kit (part 1188370) for the ICP Tempstar Heil RGS120LSCA0AAA gas furnace ignites the burners at the start of every heating cycle. When the control board calls for heat, the igniter glows white-hot and lights the gas, then the flame sensor confirms ignition. Hot surface igniters are brittle silicon-nitride or silicon-carbide elements that crack, develop hairline fractures, or burn out from repeated cycling — the most common cause of a furnace that blows cold air or fails to light. The included wiring kit replaces the aged igniter harness so you get a clean, reliable electrical connection along with the new element.

Document — Photograph the igniter bracket position and harness routing before disconnecting.
Remove — Unplug the old igniter connector, remove the mounting screw, and lift out the cracked element.
