Overview

This genuine OEM hot surface igniter (part number 1171306) with the matching igniter wiring kit (part number 1188370) is the factory ignition source for the ICP / Tempstar / Heil RGS120LTCA0AAA gas furnace. On each call for heat the control board sends voltage to the igniter, which glows red-hot to light the burners. Hot surface igniters are brittle and degrade with every heating cycle until the element finally cracks or fails. The most common no-heat furnace failure is a dead igniter — the inducer runs and the gas valve waits, but the burners never light. The included wiring kit ensures a clean, correct connection without splicing brittle factory leads.
