Overview
This is the genuine OEM igniter electrode (part number 1179966) for the ICP Tempstar Heil RGS303HFAB0AGAA gas furnace. The igniter electrode delivers the high-voltage spark that ignites the gas at the burner during each heating cycle. Over thousands of ignition cycles the electrode tip erodes, the porcelain insulator cracks, or the gap drifts out of spec — any of which prevents reliable ignition. A worn electrode is one of the most common causes of a furnace that clicks but will not light, locks out on ignition failure, or short-cycles on a cold morning. Replacing the electrode restores a clean, consistent spark and reliable burner light-off.

Compatibility
Designed as a direct OEM replacement for the ICP Tempstar Heil RGS303HFAB0AGAA furnace. The 1179966 electrode is also used across related ICP-family RGS-series furnaces that share the same burner and ignition assembly. Always confirm your existing part number before ordering.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, shut the gas, and verify zero voltage with a multimeter.
- Access — Remove the furnace burner-compartment service panel.
- Document — Photograph the igniter wire routing and bracket position before disconnecting.
- Remove — Disconnect the high-voltage spark lead, remove the electrode mounting screw, and withdraw the old electrode from the burner assembly.
- Install — Seat the new electrode, set the spark gap to the OEM specification, reattach the bracket, and reconnect the spark lead per your photo.
- Test — Restore gas and power, then start a heat call and confirm a clean spark and immediate burner light-off.
Signs You Need a Replacement
- Furnace clicks repeatedly but the burners never light.
- Ignition lockout after several failed trial-for-ignition cycles.
- Weak, intermittent, or no visible spark at the electrode.
- Cracked porcelain insulator or visibly eroded electrode tip.
