A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds.

Overview

This OEM hot surface igniter (part 1171306) with matching wiring kit (part 1188370) for the ICP / Tempstar / Heil RGS120HDCA0AAA furnace is the component that lights the burners on every heat call. On a call for heat, the control board sends voltage to the igniter, which glows white-hot to ignite the gas as the valve opens. Hot surface igniters are brittle and degrade over thousands of heating cycles — the element develops hairline cracks, weakens, and eventually fails to reach ignition temperature, leaving you with no heat. The included wiring kit (1188370) provides the correct pigtail/harness so the new igniter connects cleanly to the furnace control circuit without splicing. Never touch the igniter element with bare fingers; skin oils create hot spots that shorten its life.

Access — Remove the burner-compartment service panel.
Document — Photograph the igniter position, bracket, and wiring routing before disconnecting.
Remove — Unplug the old igniter harness, unscrew the igniter bracket, and withdraw the cracked element without touching the surface of the new one.
Install — Mount the new igniter by its bracket only, connect the new wiring kit, and route the harness clear of hot surfaces.
Test — Restore power, call for heat, and confirm the igniter glows bright orange-white and the burners light within the normal trial-for-ignition period.
