ICP Igniter Electrode for RGS300SDFA0AAAA — Direct Spark | Ships Today

Overview

This genuine OEM igniter electrode (part #1179966) for the ICP/Tempstar/Heil RGS300SDFA0AAAA furnace is the spark ignition electrode that lights the burner on a call for heat. The electrode generates a high-voltage spark across a precise gap to ignite the gas at the burner, and in many assemblies it also serves the flame-sensing function. Over time the electrode tip erodes, the ceramic insulator cracks, or carbon and corrosion build up, all of which weaken or eliminate the spark. Typical symptoms are a furnace that clicks but won't light, repeated ignition lockouts, delayed ignition with a noticeable gas smell, or short-cycling on a failed flame signal.

Installation Guide

1. Safety First — Shut off the gas supply, disconnect power, and verify zero voltage with a multimeter.
2. Access — Remove the furnace service panel to reach the burner assembly.
3. Document — Photograph the electrode position, gap, and wiring before removal.
4. Remove — Disconnect the ignition lead and unfasten the old electrode from the burner bracket, handling the ceramic carefully.
5. Install — Mount the new electrode at the correct gap and orientation, then reconnect the lead per your photo.
6. Test — Restore gas and power, call for heat, and confirm a strong spark and clean burner ignition.

Signs You Need a Replacement
