ICP Hot Surface Igniter for RGS102LRCA0AAA — Silicon Nitride with Wiring Kit | Ships Today

Overview

This OEM hot surface igniter (HSI) is the direct ignition component for the ICP/Tempstar/Heil RGS102LRCA0AAA gas furnace. The igniter glows red-hot when 120V is applied at the start of each heat cycle, lighting the burner gas. This listing includes OEM igniter 1171306 and the matching igniter wiring kit 1188370, so you have the harness and connector needed for a clean replacement. A cracked or burned-out igniter is one of the most common causes of "no heat" calls — the furnace will cycle, the inducer will run, but the burners never light.

Specifications

Compatibility

Engineered for the ICP RGS102LRCA0AAA and shared across many ICP-family gas furnaces sold under the Tempstar, Heil, Comfortmaker, and Arcoaire brands. Confirm your existing igniter part number before ordering to guarantee fitment.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter bracket and wire routing before disconnecting.
4. Remove — Unplug the igniter connector, remove the mounting screw, and lift the old igniter out without touching the ceramic element.
5. Install — Mount the new igniter, route the wiring kit, and reconnect per your photo. Never touch the silicon nitride element with bare fingers.
6. Test — Restore power and watch a full heat cycle to confirm the igniter glows and the burners light.
