Overview
This OEM hot surface igniter (HSI) is the direct-fit ignition component for the ICP Tempstar / Heil RGS121HECB0AAA gas furnace. The igniter (OEM part 1171306) is a silicon-carbide or silicon-nitride heating element that glows to roughly 2,500°F to ignite the burner gas on each heating call. Because it is the single most cycled part in the furnace, it is also the most common failure point. This listing includes the matching igniter wiring kit (OEM part 1188370) so you have the harness and connector needed for a clean replacement. Typical failure symptoms include a furnace that runs the inducer and opens the gas valve but never lights, no visible glow at the igniter, a cracked or chipped element, or a hairline fracture that reads open on a multimeter.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker. Verify zero voltage with a multimeter before proceeding.
- Access — Remove the lower burner/service panel.
- Document — Photograph the igniter bracket position and wiring before disconnecting.
- Remove — Unplug the igniter harness, remove the mounting screw, and lift the old igniter free without touching the element with bare fingers.
- Install — Mount the new igniter at the same depth and angle, install the wiring kit, and reconnect per your photo.
- Test — Restore power and run a heat cycle; confirm the igniter glows and the burners light within a few seconds.
Signs You Need a Replacement
- Inducer runs and gas valve opens but burners never ignite
- No orange/white glow visible at the igniter during a heat call
- Visible cracks, chips, or white spots on the element
