ICP Igniter Electrode for RGS300SEAA0AAAA — OEM 1179966 | Ships Today

Overview

This is a genuine OEM igniter electrode (part number 1179966) for ICP, Tempstar, and Heil gas furnaces. The igniter electrode delivers the spark (or sensing path) at the burner that lights the gas at the start of each heat cycle. Its position and gap are critical: a cracked ceramic insulator, eroded electrode tip, or carbon buildup leads to delayed ignition, repeated lockouts, or no ignition at all. Because the electrode sits directly in the burner flame path, it degrades over time and is a common no-heat culprit. Installing the correct OEM electrode restores fast, reliable ignition and clean flame sensing.

Installation Guide

1. Safety First — Shut off gas and disconnect power, then verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the electrode position, gap, and wire routing.
4. Remove — Disconnect the ignition lead and unscrew the old electrode from the burner assembly.
5. Install — Mount the new electrode at the correct gap and reconnect the lead per your photo.
6. Test — Restore gas and power, then watch a full ignition cycle for prompt, stable light-off.

Signs You Need a Replacement

• No ignition or repeated ignition lockouts.
• Delayed light-off with a small "poof" at startup.
• Cracked or chipped ceramic insulator.
• Eroded, corroded, or carbon-fouled electrode tip.
