ICP Hot Surface Igniter Kit for RGS120SFBA0AAA — with Wiring Harness | Ships Today

Overview

This OEM hot surface igniter (part number 1171306) with its matching igniter wiring kit (1188370) lights the burners on ICP, Tempstar, and Heil gas furnaces. On a heat call, the control board sends line voltage to the igniter, which glows white-hot and ignites the gas as the valve opens. Hot surface igniters are brittle and degrade with every cycle — eventually they crack, develop hot spots, or fail to reach ignition temperature, leaving you with no heat or a furnace that locks out after several trial-for-ignition attempts. The included wiring kit replaces aged, heat-stressed connectors for a clean, reliable installation on model RGS120SFBA0AAA.

Specifications

Compatibility

Designed for the ICP / Tempstar / Heil RGS120SFBA0AAA gas furnace and platform models using this igniter and harness. Verify the igniter style and connector against your existing part before ordering.

Installation Guide

1. Safety First — Shut off gas and disconnect power. Verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter position and wiring routing before disconnecting.
4. Remove — Unplug the igniter harness and unscrew the old igniter. Handle by the ceramic base only — never touch the element.
5. Install — Mount the new igniter at the correct depth, install the new wiring kit, and confirm the element sits in the burner flame path without touching metal.
6. Test — Restore gas and power, start a heat cycle, and confirm the igniter glows and lights the burners on the first try.

Signs You Need a Replacement

• No heat; furnace locks out after several ignition attempts.
• Visible cracks or breaks in the igniter element.
• Igniter glows weakly or not at all.
• Delayed ignition or burner "puff" on startup.
