Overview
The OEM Igniter Electrode (part #1179966) is the spark/ignitor electrode that starts the burner flame in your ICP Tempstar Heil RGS300HDEA0AAAA furnace. Positioned at the burner, the electrode delivers the high-voltage spark that lights the gas at the start of every heating cycle and, on many designs, also serves as the sensing point that confirms a stable flame. Because it sits directly in the burner flame path, the electrode tip erodes, cracks, or develops a carbon/oxide buildup over time, and the ceramic insulator can hairline-crack and short to ground. When it fails, the furnace clicks but won't light, ignites then locks out on a flame-sense fault, or short-cycles on repeated ignition attempts. Installing the correct OEM electrode restores a clean, reliable spark and proper gap geometry for dependable lighting.

Installation Guide
- Safety First — Disconnect power at the breaker and shut off the gas; verify zero voltage with a multimeter.
- Access — Remove the burner-compartment service panel.
- Document — Photograph the electrode position, gap, and ignition lead routing before removing.
- Remove — Disconnect the high-voltage lead, unscrew the electrode bracket, and withdraw the old electrode.
- Install — Mount the new electrode at the factory gap and reconnect the lead per your photos.
- Test — Restore gas and power, call for heat, and confirm a clean spark, ignition, and stable flame with no lockout.
Signs You Need a Replacement
- Furnace clicks/sparks but the burner won't light
- Ignites then locks out on a flame-sense or ignition fault
- Short-cycling on repeated ignition attempts
