ICP Hot Surface Igniter Kit with Wiring Harness for RGS102HTCA0AAA | Ships Today

Overview

This OEM hot surface igniter kit for the ICP / Tempstar / Heil RGS102HTCA0AAA includes the igniter (part 1171306) and the matching igniter wiring kit (part 1188370). The hot surface igniter is the component that glows red-hot when the furnace control board energizes it, igniting the gas at the burners on each call for heat. Because the igniter element is brittle and cycles through extreme thermal stress, it is one of the most common furnace failure points — and including the wiring kit ensures a clean connection with fresh terminals and a properly rated harness. A failed igniter is a leading cause of no-heat calls: the inducer runs and the gas valve opens, but without a glowing igniter the burners never light and the unit locks out.

Specifications

Compatibility

Designed for the ICP/Tempstar/Heil RGS102HTCA0AAA and related ICP-family gas furnaces using this hot surface igniter and wiring kit. Handle the igniter element by its base only — skin oils and bumps can crack the silicon carbide element.

Installation Guide

1. Safety First — Disconnect power and verify zero voltage with a multimeter.
2. Access — Remove the furnace burner-compartment service panel.
3. Document — Photograph the igniter position and wiring routing before removal.
4. Remove — Unplug the igniter harness and unfasten the old igniter, handling it only by the ceramic base.
5. Install — Mount the new igniter without touching the element, then connect the new wiring kit.
6. Test — Restore power and confirm the igniter glows and the burners light on a call for heat.

Signs You Need a Replacement

• Furnace inducer runs but burners never ignite (no-heat lockout)
• Igniter does not glow or glows weakly/unevenly
• Visible cracks, chips, or breaks in the igniter element
• Repeated ignition-failure fault codes on the control board
