ICP Hot Surface Igniter Electrode for RGS240SRAA0AAAA — OEM Ignitor | Ships Today

Overview

This genuine OEM igniter electrode (part #1179966) is the ignition source for the ICP RGS240SRAA0AAAA gas furnace. On a heat call, the control board energizes the igniter; it glows hot and lights the burners as the gas valve opens. Igniters are a normal wear item — repeated heating and cooling cycles eventually crack the brittle element or cause it to fail open. A bad igniter is the most common cause of a furnace that ignites intermittently or fails to light at all, often producing a system lockout after several failed attempts.

Specifications

Compatibility

Directly fits the ICP/Tempstar/Heil RGS240SRAA0AAAA gas furnace and related ICP-family models using this igniter electrode assembly. Verify the connector style and mounting bracket against your existing igniter before installing.

Installation Guide

1. Safety First — Shut off gas and disconnect power at the furnace switch, then verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter position and wiring before disconnecting.
4. Remove — Unplug the igniter connector and remove the mounting screw(s); handle the old element by the ceramic base only.
5. Install — Mount the new igniter without touching the silicon-carbide element with bare fingers, then reconnect the plug.
6. Test — Restore gas and power, start a heat cycle, and confirm the igniter glows and lights the burners.

Signs You Need a Replacement

• Furnace clicks but burners never light
