Overview
This genuine OEM igniter electrode (part number 1179966) is the ignition component for the ICP/Heil/Tempstar RGS303LTAA0AAAA gas furnace. The electrode generates the spark that lights the burner gas on each heat call and, on combined sense/ignite designs, monitors the resulting flame so the control board knows ignition succeeded. Because it sits directly in the burner flame path, the electrode tip erodes, cracks, or builds up oxide over time. A failing electrode shows up as a furnace that clicks or sparks but won't light, ignites then immediately shuts down on a flame-sense fault, or short-cycles on the burner. Replacing this electrode with the correct OEM part restores fast, reliable light-off and stable burner operation through the heating season.

Installation Guide
- Safety First — Shut off the gas supply and disconnect electrical power, then verify zero voltage with a multimeter.
- Access — Remove the furnace burner/service panel to expose the burner assembly.
- Document — Photograph the electrode position, ignition wire routing, and ground strap before disconnecting.
- Remove — Disconnect the high-voltage ignition lead and remove the mounting screw(s) holding the old electrode.
- Install — Mount the new electrode, set it in the burner flame path, and reconnect the ignition lead per your photo.
- Test — Restore gas and power, run a heat call, and confirm prompt spark, light-off, and a steady flame.
Signs You Need a Replacement
- Furnace sparks or clicks but the burner won't ignite.
- Burner lights then drops out on a flame-sense / ignition lockout.
- Cracked ceramic insulator or eroded electrode tip.
- Repeated ignition retries and short-cycling on heat calls.
