ICP Hot Surface Igniter for RGS243HEBH0AGAA — Igniter Electrode | Ships Today

Overview

This OEM hot surface igniter electrode (part 1179966) lights the gas burners on the heating section of your ICP RGS243HEBH0AGAA packaged gas/electric unit. On a heat call the control board sends 120V to the igniter, which glows white-hot and ignites the gas as the valve opens. Hot surface igniters are a normal wear item — the brittle silicon-carbide or nitride element cracks from thermal cycling, dropping resistance and leaving the burners unable to light. A failed igniter is the most common cause of a furnace that clicks and tries but produces no heat.

Specifications

Compatibility

Built for the ICP RGS243HEBH0AGAA and matching RGS243-series packaged units sold under Heil, Tempstar, Comfortmaker, and Arcoaire. Confirm the igniter style and mounting bracket against your original before ordering.

Installation Guide

1. Safety First — Disconnect power and shut off the gas, then verify zero voltage with a multimeter.
2. Access — Remove the burner/heat-section service panel.
3. Document — Photograph the igniter position and wire routing before disconnecting.
4. Remove — Unplug the connector and remove the mounting screw; handle by the ceramic base only — never touch the element.
5. Install — Mount the new igniter, never touching the hot surface, and reconnect the plug.
6. Test — Restore gas and power, then watch a full ignition cycle confirm a strong burner light.

Signs You Need a Replacement

• No heat — unit cycles but burners never ignite
• Visibly cracked or broken igniter element
• Igniter glows weakly or not at all on a heat call
• Out-of-range resistance reading (open circuit)
