Overview
This OEM hot surface igniter (part 1171306), bundled with the matching igniter wiring kit (part 1188370), is the component that lights the burners in your ICP, Tempstar, and Heil RGS120LTCB0AAA gas furnace. On each heat call the control board sends voltage to the igniter, which glows white-hot and ignites the gas as it leaves the burners. Hot surface igniters are brittle silicon-carbide or silicon-nitride elements that degrade with every heating cycle and eventually crack or lose conductivity. A failed igniter is the single most common cause of "no heat" on a modern furnace — the inducer runs and the gas valve tries to open, but without ignition the board locks out on a failed-ignition fault. The included wiring kit ensures a clean, correct electrical connection and replaces brittle or heat-damaged leads at the same time.

Compatibility
Direct OEM replacement for the ICP / Tempstar / Heil RGS120LTCB0AAA gas furnace. The 1171306 igniter and 1188370 wiring kit are shared across numerous ICP-family condensing and mid-efficiency furnaces — verify the part numbers and the igniter mounting style before installing.
Installation Guide
- Safety First — Shut off gas and disconnect power at the switch or breaker; verify zero voltage with a multimeter.
- Access — Remove the burner compartment door to expose the burner assembly and igniter.
- Document — Photograph the igniter position and wiring routing before removal.
- Remove — Unplug the igniter lead, remove the mounting screw, and lift the old igniter out. Handle only by the ceramic base — never touch the element.
- Install — Seat the new igniter at the correct position over the burner, secure the screw, and connect the new wiring kit per your photo.
- Test — Restore gas and power, then watch a full ignition cycle to confirm the igniter glows and the burners light promptly.
Signs You Need a Replacement
- Furnace blows cold air — no flame on a heat call
- Igniter does not glow, or glows weakly
- Control board locks out on a failed-ignition / ignition-lockout code
- Visible cracks, hot spots, or whitish wear on the igniter element
