ICP Hot Surface Igniter Kit for RGS121LRCB0AAA — OEM 1171306 | Ships Today

Overview

This genuine OEM hot surface igniter (part number 1171306) with matching igniter wiring kit (1188370) ignites the burners on the ICP / Heil / Tempstar RGS121LRCB0AAA gas furnace. On a heat call, the control board sends voltage to the igniter, which glows red-hot to light the gas at the burners. Hot surface igniters are brittle and degrade with every cycle; they crack, develop hairline fractures, or simply burn out. A failed igniter is one of the most common causes of no-heat calls. The included wiring kit ensures a clean, factory-spec electrical connection.

Specifications

Compatibility

Designed for the ICP-family RGS121LRCB0AAA furnace and related RGS-series models using this hot surface igniter. Confirm your model number before ordering, and handle the igniter only by its ceramic base — never touch the silicon-carbide element.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker. Verify zero voltage with a multimeter.
2. Access — Remove the burner compartment door.
3. Document — Photograph the igniter position, bracket, and wiring before disconnecting.
4. Remove — Unplug the igniter harness, remove the mounting screw, and lift out the old igniter without touching the element.
5. Install — Mount the new igniter, install the wiring kit, and route the harness clear of the burner flame path.
6. Test — Restore power and watch a full ignition cycle to confirm the igniter glows and lights the burners.

Signs You Need a Replacement

• Furnace blower runs but no heat (no ignition)
