ICP Hot Surface Igniter Electrode for RGS300HSAA0AAAA — OEM 1179966 | Ships Today

Overview

This OEM igniter electrode (part 1179966) provides the ignition source that lights the burners in your ICP RGS300HSAA0AAAA furnace. On a call for heat, the control board sends voltage to the igniter, which glows hot and ignites the gas as it flows across the burners. Igniters are a wear item — the element is brittle and degrades with every heating cycle. A failed igniter is one of the most common causes of no-heat calls: the furnace runs the inducer and opens the gas valve, but the burners never light, so the unit locks out on ignition failure. This direct-fit electrode restores reliable, fast ignition.

Specifications

Compatibility

Built for the ICP RGS300HSAA0AAAA gas furnace and the related Heil, Tempstar, and Comfortmaker models that share this burner assembly. Confirm the mounting bracket and electrode geometry match your original before installing.

Installation Guide

1. Safety First — Shut off gas and disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter.
2. Access — Remove the furnace burner-compartment door.
3. Document — Photograph the igniter position and wiring before removing it.
4. Remove — Unplug the igniter connector and remove the mounting screw. Handle the new element by its ceramic base only — never touch the silicon-carbide tip.
5. Install — Mount the new igniter in the same position, reconnect the plug, and confirm proper alignment over the burner.
6. Test — Restore gas and power, then run a heat cycle and verify the igniter glows and the burners light promptly.

Signs You Need a Replacement

• Furnace runs but burners never ignite (ignition lockout)
• Visible cracks or breaks in the igniter element
• No glow during the ignition sequence
• Repeated short-cycling or delayed ignition with a small pop
