ICP Hot Surface Igniter Kit for RGS120LRCA0AAA — with Wiring | Ships Today

Overview

This genuine OEM ICP hot surface igniter kit for the RGS120LRCA0AAA gas furnace includes the igniter (part 1171306) and the matching igniter wiring kit (part 1188370). The hot surface igniter glows red-hot when energized by the control board to ignite the gas at the burners on each heat call. Igniters are brittle and wear out from repeated heating cycles, thermal stress, and contamination. When the igniter fails, the furnace will not light — you'll hear the inducer and gas valve cycle but get no flame, often followed by a lockout. The included wiring kit ensures a clean, corrosion-free electrical connection so the new igniter receives full voltage.

Specifications

Compatibility

Designed for the ICP / Tempstar / Heil RGS120LRCA0AAA gas furnace and related RGS-series furnaces using this hot surface ignition system. Confirm your existing igniter part number before ordering.

Installation Guide

1. Safety First — Disconnect power and shut off the gas; verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter position, mounting, and wiring routing before removal.
4. Remove — Disconnect the igniter harness, unscrew the bracket, and carefully withdraw the old igniter (handle by the base, never the element).
5. Install — Mount the new igniter, install the new wiring kit, and reconnect, avoiding any contact with the fragile element.
6. Test — Restore gas and power, then run a heat cycle to confirm the igniter glows and ignites the burners.

Signs You Need a Replacement

• Furnace cycles the inducer and valve but produces no flame
• No visible glow at the igniter during the ignition sequence
• Cracked or broken igniter element
