ICP Hot Surface Igniter Electrode for RGS303STFA0AAAA — OEM 1179966 | Ships Today

Overview

This genuine OEM hot surface igniter electrode (part number 1179966) lights the burners on the ICP/Tempstar/Heil RGS303STFA0AAAA gas furnace. On each call for heat, the control board energizes the igniter, which glows white-hot to ignite the gas as the valve opens. Igniters are brittle and degrade over time — a cracked element, a no-glow condition, or repeated ignition lockouts mean the furnace produces no heat. Replacing with the correct OEM igniter restores fast, dependable ignition. Handle only by the ceramic base; finger oils shorten element life.

Compatibility

Engineered as the factory replacement for the ICP/Tempstar/Heil RGS303STFA0AAAA gas furnace and shared family variants that originally used part 1179966. Match the connector and mounting bracket to your existing igniter before ordering.

Installation Guide

1. Safety First — 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, bracket, and wire routing before disconnecting.
4. Remove — Unplug the igniter connector, remove the mounting screw, and carefully withdraw the old element.
5. Install — Handle the new 1179966 only by its ceramic base, mount it in the same position, and reconnect the plug.
6. Test — Restore power and confirm the igniter glows and the burners light on the first ignition cycle.
