ICP Hot Surface Igniter Electrode for RGS300SSEA0AAAA — OEM | Ships Today

Overview

This genuine OEM igniter electrode, ICP part number 1179966, is the hot surface ignition element that lights the burners on your RGS300SSEA0AAAA gas furnace. On each heat call, the control board sends line voltage to the igniter, which glows incandescent-hot and ignites the gas as it flows across the burners. Igniters are brittle and degrade with every thermal cycle, so they are one of the most common no-heat failures. A cracked or open igniter leaves the furnace unable to start a burner cycle even though the blower and controls are working normally.

Specifications

Compatibility

Engineered as the factory replacement for the ICP/Tempstar/Heil RGS300SSEA0AAAA and related RGS-series gas furnaces that call out OEM part 1179966. Handle the ceramic element only by its bracket — skin oils and impacts shorten its life. Confirm the mounting bracket and connector match your existing igniter before installing.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter position, bracket, and wire routing before removing it.
4. Remove — Unplug the igniter connector and unfasten the mounting screw, then lift the old igniter clear.
5. Install — Set the new igniter so the element aligns to the burner port, handling it only by the bracket, and plug in the connector.
6. Test — Restore power and confirm the igniter glows and lights the burners on a heat call.

Signs You Need a Replacement

• Igniter shows visible cracks, blisters, or no longer glows.
• Furnace locks out after several failed ignition attempts.
