ICP Hot Surface Igniter Electrode for RGS243SDAA0AAAA — Ships Today

Overview

This is a genuine OEM hot surface igniter electrode (part number 1179966, "Ignitor Electrode") for the ICP RGS243SDAA0AAAA gas furnace. On a call for heat the control board energizes the igniter, which glows red-hot and lights the burner gas. It is one of the most replaced parts on a modern furnace because the heating element is brittle and degrades with every ignition cycle. A cracked or worn igniter is the most common cause of a furnace that clicks, runs the inducer, but never lights — leaving you with cold air or a no-heat lockout.

Specifications

Compatibility

Direct-fit replacement for the ICP RGS243SDAA0AAAA furnace and other ICP-family (Tempstar, Heil, Comfortmaker) models using this igniter assembly. Match the mounting bracket and connector style to your original before installing.

Installation Guide

1. Safety First — Turn off gas and disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter position and wire routing before disconnecting.
4. Remove — Unplug the igniter connector and remove the mounting screw. Handle only by the ceramic base — never touch the silicon-nitride element.
5. Install — Mount the new igniter, keeping fingers off the element, and reconnect the plug.
6. Test — Restore gas and power, call for heat, and confirm the igniter glows and the burners light.

Signs You Need a Replacement
