Overview
This OEM hot surface igniter (ignitor electrode), part number 1179966, is the direct-replacement ignition component for the ICP / Tempstar / Heil RGS303HSAA0AAAA gas furnace. The igniter is energized at the start of each heat cycle, glowing red-hot to light the burner gas. It is one of the most common furnace failure points because the brittle silicon-carbide element degrades with every ignition cycle. Typical failure symptoms include the furnace blower running with no heat, the burners failing to light, repeated ignition lockouts (often shown as flashing LED fault codes on the control board), or a visibly cracked, pitted, or white-coated igniter tip. Replacing a worn igniter restores reliable, fast first-try ignition.

Installation Guide
- Safety First – Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter.
- Access – Remove the furnace burner-compartment service panel.
- Document – Photograph the igniter wiring and bracket orientation before disconnecting.
- Remove – Unplug the igniter harness, remove the mounting screw, and carefully withdraw the old igniter without touching the element.
- Install – Mount the new igniter by the ceramic base only (never touch the silicon-carbide tip), secure the screw, and reconnect the harness per your photo.
- Test – Restore power and run a heat cycle; confirm the igniter glows and the burners light on first try.
Signs You Need a Replacement
- Furnace blower runs but produces no heat.
- Burners fail to light or light intermittently.
