Overview

This genuine OEM hot surface igniter (part #1171306) with matching igniter wiring kit (part #1188370) is the ignition source for the ICP / Heil / Tempstar RGS121LEAB0AAAA gas furnace. On a call for heat, the control board sends voltage to the igniter, which glows white-hot to light the gas at the burners. Hot surface igniters are brittle and degrade over time from thermal cycling and contamination, eventually cracking or failing to reach ignition temperature. The included wiring kit ensures a clean, secure connection and is the recommended replacement whenever the igniter is changed.
