ICP Igniter Electrode for RGS300HEFA0AAAA — Direct-Spark Ignition | Ships Today

Overview

This OEM igniter electrode (part 1179966) is responsible for lighting the burners in your ICP RGS300HEFA0AAAA gas furnace. The electrode delivers the spark that ignites the gas at the burner, starting every heat cycle. A cracked ceramic insulator, eroded electrode tip, or carbon-fouled gap is the usual cause of failure. Common symptoms include no ignition, repeated failed light-off attempts, the furnace locking out after several tries, or short-cycling on a call for heat. Because it is a wear item exposed to high heat on every cycle, the igniter electrode is one of the most replaced components in a gas furnace.

Compatibility

Direct OEM fit for the ICP / Tempstar / Heil RGS300HEFA0AAAA gas furnace. Confirm the OEM part number against your unit's parts list to ensure the electrode geometry and mounting match your burner assembly.

Installation Guide

1. Safety First — Shut off the gas supply and disconnect power, then verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter position, wiring, and gap before removing anything.
4. Remove — Disconnect the igniter lead and unscrew the electrode from the burner bracket. Handle by the base only — never touch the element.
5. Install — Mount the new electrode at the correct position and reconnect the ignition lead per your photo.
6. Test — Restore gas and power, then confirm clean ignition on the first call for heat.

Signs You Need a Replacement

• Furnace fails to ignite or makes repeated failed attempts.
• Visible crack in the ceramic insulator or eroded electrode tip.
• Control board lockout after multiple ignition tries.
• Intermittent ignition or short-cycling on heat calls.
