Overview
This OEM hot surface igniter (electrode) is the ignition component for the ICP Tempstar Heil RGS303HTFA0AAAA gas furnace. When the thermostat calls for heat, the furnace control board energizes this igniter, heating its silicon-nitride element to roughly 2,000°F to light the burner gas. A cracked, carbon-fouled, or open igniter is one of the most common causes of no-heat calls. Failure symptoms include a furnace that runs the inducer and gas valve but never lights, repeated lockouts after several ignition attempts, a glowing igniter that no longer reaches full temperature, or visible cracks in the element. This is OEM part number 1179966 (IGNITOR ELECTRODE).

Compatibility
Engineered as a direct-fit replacement for the ICP Tempstar Heil RGS303HTFA0AAAA gas furnace and other ICP-family models that specify part 1179966. ICP, Heil, Tempstar, and Comfortmaker furnaces share many ignition components, so always confirm against your unit's part list before ordering.
Installation Guide
- Safety First – Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter. Shut off the gas supply.
- Access – Remove the burner-compartment service panel.
- Document – Photograph the igniter position and wiring before disconnecting.
- Remove – Unplug the igniter wire harness, then remove the mounting screw(s). Handle the old igniter by the ceramic base only.
- Install – Mount the new igniter without touching the element surface (skin oils cause hot spots and early failure). Secure the screw and reconnect the harness per your photo.
- Test – Restore gas and power, then run a heat cycle and confirm the igniter glows and lights the burners cleanly.
Signs You Need a Replacement
- Furnace inducer and gas valve cycle but burners never ignite.
- Igniter shows cracks, blisters, or no longer glows.
- Repeated ignition lockouts (3-strike fault) on the control board.
- Weak or dim glow that fails to reach light-off temperature.
