ICP Hot Surface Ignitor Electrode for RGS300STEA0AAAA — OEM 1179966 | Ships Today

Overview

This is a genuine OEM ignitor electrode for the ICP / Tempstar / Heil RGS300STEA0AAAA, ICP part number 1179966. The ignitor is the heart of the furnace's ignition sequence: when the control board calls for heat, the element heats to a glowing temperature and lights the gas at the burners. Ignitors are fragile and degrade with every heating cycle — the element becomes brittle, develops hairline cracks, and eventually fails to reach ignition temperature. A failed ignitor is the most common cause of a furnace that runs its inducer and clicks the gas valve but produces no flame, leaving the home with no heat. Replacing a worn ignitor restores reliable, on-demand ignition.

Specifications

Compatibility

A direct OEM replacement for ICP, Tempstar, Heil, and Comfortmaker furnaces on the RGS300 platform, including model RGS300STEA0AAAA. Match ICP part 1179966 and verify the bracket and connector orientation before installing.

Installation Guide

1. Safety First — Disconnect power and shut off the gas, then verify zero voltage with a multimeter.
2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the ignitor position and wiring before disconnecting.
4. Remove — Unplug the connector, remove the mounting screw, and lift the old ignitor out — handle only by the ceramic base, never the element.
5. Install — Mount the new ignitor without touching the element, then reconnect the harness per your photo.
6. Test — Restore power and gas, then watch a full cycle to confirm the ignitor glows and the burners light.

Signs You Need a Replacement

• Furnace cycles the inducer and gas valve but never lights.
• Visible cracks or a broken element on the ignitor.
• Ignitor that no longer glows during a heat call.
• Repeated lockouts after several failed ignition attempts.
