Overview

This OEM hot surface igniter (Part No. 1171306) with its matched wiring kit (Part No. 1188370) lights the burners in your ICP / Tempstar / Heil RGS120LDAA0AGAA gas furnace. On a call for heat, the control board sends voltage to the igniter, which glows red-hot and ignites the gas as it enters the burners. Hot surface igniters are brittle and degrade over time from thermal cycling, cracking, or carbon buildup. The included wiring harness ensures a clean, plug-and-play electrical connection. Common failure symptoms include no ignition, a furnace that locks out after several failed light attempts, or an igniter that no longer glows. Replacing the igniter and harness together restores dependable startup.
