ICP Hot Surface Igniter with Wiring Kit for RGS121STBA0AAAA — OEM | Ships Today

Overview

This OEM hot surface igniter kit pairs the igniter (part #1171306) with its matching wiring kit (part #1188370) for ICP, Tempstar, and Heil RGS-series gas furnaces. On a call for heat, the control board energizes the igniter, which glows red-hot and lights the burners as gas is released. The igniter element is brittle and degrades with every heating cycle, making it one of the most common no-heat failure points. The included wiring kit provides the correct connector and leads, so you can replace a cracked igniter and a damaged or brittle harness in one repair instead of fighting a corroded plug. Never touch the element with bare fingers — skin oils shorten its life.

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 connector before removal.
4. Remove — Unplug the harness, remove the mounting screw, and lift out the cracked igniter — handle by the ceramic base only.

6. Test — Restore gas and power, start a heat cycle, and confirm the igniter glows and lights the burners.
