Overview
This is the genuine OEM igniter electrode (part number 1179966) for the ICP / Tempstar / Heil RGS303HSEA0AAAA gas furnace. The igniter electrode is the heart of the ignition system: it creates the high-voltage spark or hot ignition point that lights the main burners on each call for heat. Positioned at the burner assembly, it works with the control board and flame-sensing circuit to start and confirm combustion. When this component cracks, erodes, or carbons over, the furnace will fail to light, short-cycle, or lock out on ignition failure — leaving the home without heat. Replacing a worn igniter electrode is one of the most common heating repairs and restores reliable, on-demand ignition.

Compatibility
Engineered as a direct OEM fit for the ICP / Tempstar / Heil RGS303HSEA0AAAA gas furnace. ICP-family equipment (Heil, Tempstar, Comfortmaker, Arcoaire, KeepRite) shares many burner and ignition components, so always confirm against your unit's part number before ordering.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then shut off the gas supply. Verify zero voltage with a multimeter.
- Access — Remove the furnace front service panels to expose the burner assembly.
- Document — Photograph the igniter position, gap, and any wiring before disconnecting.
- Remove — Unplug the igniter lead and remove the mounting screw(s) securing the electrode bracket. Withdraw the old electrode without touching the ceramic insulator.
- Install — Mount the new electrode in the same position, restore the factory spark gap, and reconnect the lead per your photo.
- Test — Restore gas and power, then run a heat cycle and confirm the burners light promptly and stay lit.
Signs You Need a Replacement
- Furnace fails to light or locks out on ignition failure
- Repeated clicking or sparking with no flame
