ICP Igniter Electrode for RGS243STFA0AAAA — OEM Hot Surface Ignitor | Ships Today

Overview

This genuine ICP igniter electrode (OEM #1179966) is the hot surface ignitor that lights the burners on the RGS243STFA0AAAA gas furnace. On a call for heat, the control board sends line voltage to the element, which glows red-hot and ignites the gas as the valve opens. Igniters are brittle and consumable — they degrade with every cycle and eventually crack or burn out. The classic failure is a furnace that runs the inducer and clicks but never lights, often locking out after several attempts. A hairline crack or a dull glow both point to a worn igniter. Handle the element by its base only, never the fragile glow tip.

Specifications

Compatibility

Installation Guide

1. Safety First — Disconnect power and verify zero voltage with a multimeter; shut off the gas supply.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter position and wiring before disconnecting.
4. Remove — Unplug the connector, remove the mounting screw, and lift out the old igniter without touching the element.
5. Install — Mount the new igniter by its bracket, handling only the base, and reconnect the plug.
6. Test — Restore gas and power, call for heat, and confirm the element glows and the burners light promptly.
