ICP Hot Surface Igniter Kit for RGS120HSAA0AGAA | Ships Today

Overview

This is the genuine OEM hot surface igniter kit for the ICP / Heil / Tempstar RGS120HSAA0AGAA gas furnace, including igniter part number 1171306 and igniter wiring harness kit part number 1188370. On each call for heat the control board sends voltage to the igniter, which glows white-hot and lights the gas at the burners. The matched wiring kit ensures a clean, correct electrical connection – brittle or corroded igniter leads are a common hidden cause of intermittent ignition. Hot surface igniters are fragile silicon-nitride or silicon-carbide elements that degrade with every heating cycle and crack easily if touched.

Specifications

Compatibility

Built for the ICP RGS120HSAA0AGAA 120,000 BTU gas furnace and shared across ICP-manufactured Heil, Tempstar, and Comfortmaker RGS-series furnaces using this igniter and connector. Confirm the mounting tab and plug match your existing igniter before installing.

Installation Guide

1. Safety First – Disconnect electrical power, shut off gas, and verify zero voltage with a multimeter.
2. Access – Remove the burner-compartment service panel.
3. Document – Photograph the igniter position and harness routing before disconnecting.
4. Remove – Unplug the harness and remove the igniter mounting screw; handle the old element by its ceramic base only.
5. Install – Mount the new igniter without touching the glow element, then connect the new wiring kit.
6. Test – Restore gas and power, start a heat cycle, and verify the igniter glows and lights the burners promptly.

Signs You Need a Replacement
