ICP Hot Surface Igniter Kit for RGS120LSAA0AGAA – OEM 1171306 | Ships Today

Overview

This genuine OEM hot surface igniter (part number 1171306), supplied with its matching igniter wiring kit (1188370), is the ignition source for the ICP Tempstar Heil RGS120LSAA0AGAA gas furnace. On a heat call, the control board energizes the igniter, which glows red-hot to light the gas at the burners. Hot surface igniters are brittle and degrade with thermal cycling — they crack, develop hairline fractures, or lose conductivity over time. A failed igniter is one of the most common causes of "no heat," typically showing as the inducer running but the burners never lighting. The included wiring kit ensures a clean, correct electrical connection at install.

Compatibility

Designed for the ICP Tempstar Heil RGS120LSAA0AGAA and related ICP-family gas furnaces using this hot surface igniter and connector. Verify the igniter element and plug style match your existing part.

Installation Guide

1. Safety First – Turn off gas and disconnect power. Verify zero voltage with a multimeter.
2. Access – Remove the burner compartment door.
3. Document – Photograph the igniter mounting and wiring before removal.
4. Remove – Unplug the igniter harness, remove the mounting screw(s), and lift out the old igniter — handle only by the ceramic base, never the element.
5. Install – Mount the new igniter (do not touch the silicon-carbide element with bare fingers), then connect using the supplied wiring kit.
6. Test – Restore gas and power, start a heat cycle, and confirm the igniter glows and the burners light promptly.

Signs You Need a Replacement

• Inducer runs but burners never ignite (no heat)
