Overview
This OEM hot surface igniter (HSI) is the ignition source for the ICP / Tempstar / Heil RGS121LTCB0AAA gas furnace. When the thermostat calls for heat, the control board energizes the igniter, which glows red-hot and ignites the gas at the burners. Over thousands of heating cycles the silicon-carbide or silicon-nitride element develops hairline cracks and fails to reach ignition temperature — the most common cause of a furnace that clicks, runs the inducer, but never lights. This part bundles OEM igniter 1171306 with the matching 1188370 wiring/connector kit so the harness terminates correctly without splicing.

Compatibility
Direct-fit replacement for the ICP Tempstar Heil RGS121LTCB0AAA furnace and other ICP-family models that originally used igniter 1171306. Always verify your existing igniter part number and mounting bracket before installing.
Installation Guide
- Safety First — Shut off gas and disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter.
- Access — Remove the lower service / burner compartment panel.
- Document — Photograph the igniter wiring and connector routing before disconnecting.
- Remove — Unplug the igniter connector, remove the mounting screw, and lift the old igniter out of the burner box. Handle only by the ceramic base — never touch the element.
- Install — Mount the new igniter so the element sits in the burner flame path, secure the screw, and connect the supplied 1188370 wiring kit per your photo.
- Test — Restore gas and power, run a heat cycle, and confirm the igniter glows and the burners light within a few seconds.
Signs You Need a Replacement
- Furnace inducer runs but burners never ignite (no glow).
- Visible cracks or chips in the igniter element.
- Intermittent ignition or repeated lockouts after several cycles.
- No heat on a system that otherwise sequences normally.
