Overview
This OEM hot surface igniter (ignitor electrode, part number 1179966) is the ignition component for the ICP/Heil/Tempstar RGS300LSFA0AAAA gas furnace. When the thermostat calls for heat, the control board energizes the igniter; it glows to a high temperature and lights the burner gas. Hot surface igniters are brittle and degrade with every heating cycle, eventually cracking or losing the ability to reach ignition temperature. Common failure symptoms include a furnace that clicks and tries to ignite but never lights, a glowing igniter that produces no flame, repeated lockouts after three failed ignition attempts, or no glow at all. Replacing a worn igniter restores reliable, single-attempt ignition and prevents nuisance no-heat calls during cold weather.

Installation Guide

- Access — Remove the burner-compartment service panel.
- Document — Photograph the igniter position and wiring before disconnecting.
- Remove — Unplug the igniter connector, remove the mounting screw, and carefully lift out the old igniter without touching the silicon element.
- Install — Mount the new igniter in the same position, handling only the ceramic base, and reconnect the plug per your photo.
- Test — Restore gas and power, then run a heat cycle and confirm the igniter glows and lights the burners on the first attempt.
