ICP Hot Surface Igniter Electrode for RGS300HTEA0AAAA — OEM 1179966 | Ships Today

Overview

This OEM igniter electrode (part #1179966) is the hot surface ignitor that lights the gas burners in your ICP Tempstar/Heil RGS300HTEA0AAAA gas furnace. On a heat call, line voltage energizes the igniter element, which glows white-hot and ignites the gas as it exits the burner ports. It is one of the most common furnace failure points because the brittle silicon-nitride/carbide element degrades with every heating cycle and eventually cracks. Symptoms of a failed igniter include no heat, a furnace that cycles but never lights, or a unit that locks out after several failed ignition attempts. Replacing the igniter is routine seasonal maintenance on high-cycle systems.

Specifications

Compatibility

Direct-fit replacement for the ICP Tempstar Heil RGS300HTEA0AAAA gas furnace and related RGS300 series models. Always confirm the mounting bracket and connector orientation against your original igniter before installing.

Installation Guide

1. Safety First — Shut off gas and disconnect power; verify zero voltage with a multimeter.
2. Access — Remove the furnace burner-compartment door.
3. Document — Photograph the igniter position and wiring before disconnecting.
4. Remove — Unplug the connector and remove the mounting screw; handle the old igniter by the ceramic base only.
5. Install — Mount the new igniter without touching the element, then reconnect the plug.
6. Test — Restore gas and power and confirm the igniter glows and the burners light on a heat call.

Signs You Need a Replacement

• No heat despite the blower and inducer running
• Furnace locks out after repeated ignition attempts
• Igniter shows cracks or no longer glows
• Visible breaks in the element or a no-continuity ohm reading
