ICP Hot Surface Igniter for RGS300HFEA0AAAA — Electrode Assembly | Ships Today

Overview

This genuine OEM ignitor electrode (part 1179966) is the hot surface igniter for the ICP RGS300HFEA0AAAA gas furnace. On a call for heat the control board sends line voltage to the igniter, its ceramic element glows white-hot, and that heat ignites the gas at the burners. The igniter is the single most common no-heat failure point in a modern furnace because the brittle element degrades with every heating cycle. Typical failure symptoms are a furnace that goes through its inducer and gas-valve sequence but never lights, an igniter that no longer glows, a visibly cracked or chipped element, or repeated ignition lockouts.

Specifications

Compatibility

Direct-fit replacement for the ICP RGS300HFEA0AAAA furnace and shared ICP-family gas furnaces marketed as Heil, Tempstar, and Comfortmaker. Match the mounting bracket and connector to your existing igniter before installing.

Installation Guide

1. Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter.
2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the igniter position and wiring before disconnecting.
4. Remove — Unplug the igniter harness and remove the mounting screw(s); handle the ceramic element by its base only — never touch the element.
5. Install — Seat the new igniter at the correct depth in the burner flame path and reconnect the harness.
6. Test — Restore power and confirm the igniter glows and the burners light on a heat call.

Signs You Need a Replacement

• Furnace runs the ignition sequence but never lights.
• Igniter does not glow when energized.
• Visible cracks, chips, or hot spots on the ceramic element.
