ICP Hot Surface Igniter Electrode for RGS303SEAA0AAAA — OEM 1179966 | Ships Today

Overview

This is a genuine OEM igniter electrode (Part No. 1179966) for the ICP / Tempstar / Heil RGS303SEAA0AAAA gas furnace. On each heat call, the furnace control sends voltage to the igniter, which heats to a glowing temperature and lights the gas at the burners. Hot surface igniters are brittle and degrade with every ignition cycle; they eventually crack, develop hairline fractures, or burn out entirely. A failed igniter is the single most common no-heat complaint — the inducer runs and the gas valve tries to open, but the burners never light, and the furnace locks out after a few attempts.

Specifications

Compatibility

Designed for the ICP family gas furnace model RGS303SEAA0AAAA (also branded Tempstar, Heil, and Comfortmaker). Confirm the OEM part number and connector style against your original igniter before ordering. Handle the new igniter only by its ceramic base — never touch the silicon-carbide element.

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 wiring harness before removal.
4. Remove — Unplug the igniter connector and remove the mounting screw(s); discard the cracked element carefully.
5. Install — Mount the new 1179966 igniter handling it by the base only, then 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

• No heat — burners never light despite a call for heat
• Visible cracks or breaks in the igniter element
• Igniter does not glow when energized
• Furnace locks out after several failed ignition attempts
