ICP Hot Surface Igniter Electrode for RGS300SFFA0AAAA — OEM | Ships Today

Overview

This OEM ignitor electrode (part number 1179966) is the hot surface igniter that lights the gas burners in your ICP RGS300SFFA0AAAA furnace. On each heat call, the control board sends voltage to the igniter, which heats to a high temperature and ignites the gas as the valve opens. Igniters are fragile and consumable: the element is brittle, degrades with every thermal cycle, and eventually cracks or loses the ability to reach ignition temperature. A failed igniter is one of the most common causes of no-heat calls — the inducer and gas valve may sequence correctly, but the burners never light, and the furnace locks out. Replacing it with the genuine OEM hot surface igniter restores reliable ignition and proper heating cycles.

Specifications

Compatibility

Designed for the ICP / Tempstar / Heil RGS300SFFA0AAAA furnace and other units specifying OEM part 1179966. Verify the part number against your unit's parts list before ordering to ensure exact fitment.

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 igniter position and wiring before removal.
4. Remove — Unplug the igniter connector and remove the mounting screw(s); handle by the ceramic base only — never touch the element.
5. Install — Mount the new igniter in the exact original position and reconnect the wiring harness.
6. Test — Restore gas and power, start a heat call, and confirm the igniter glows and the burners light.

Signs You Need a Replacement

• No heat — burners never ignite on a heat call.
• Igniter does not glow or glows weakly.
• Visible cracks or breaks in the igniter element.
• Furnace locks out after several failed ignition attempts.
