ICP Ignitor Electrode for RGS303SDEA0AAAA — Direct Spark Igniter | Ships Today

Overview

This genuine OEM ignitor electrode, part number 1179966, provides the ignition spark for the ICP / Tempstar / Heil RGS303SDEA0AAAA gas furnace. The electrode positions precisely in the burner flame path to ignite gas at the burner and, in many designs, to confirm flame presence. A cracked ceramic insulator, eroded electrode tip, or carbon buildup leads to failed ignition, repeated ignition lockouts, or a furnace that tries to light but never establishes a flame.

Installation Guide

1. Safety First — Shut off the gas supply, disconnect power, and verify zero voltage with a multimeter.
2. Access — Remove the burner compartment door.
3. Document — Photograph the electrode position, gap, and wire routing before removal.
4. Remove — Disconnect the ignition lead, remove the mounting screw(s), and withdraw the electrode from the burner.
5. Install — Seat the new electrode at the correct gap and position, reconnect the lead, and reinstall the screws.
6. Test — Restore gas and power, then run a heat cycle and confirm a strong, consistent spark and clean ignition.
