ICP Hot Surface Igniter Electrode for RGS300HFFA0AAAA — Furnace Ignition | Ships Today

Overview

This OEM igniter electrode (part 1179966) is the component that lights the burners on your ICP RGS300HFFA0AAAA gas furnace. On each heat call the control board energizes the igniter, it heats to ignition temperature, and the gas valve opens to light the main burners. Igniters are a wear item — thermal cycling eventually cracks the element or breaks the electrode tip. The classic failure pattern is a furnace that runs the inducer and clicks the gas valve but never lights, often locking out after several retries.

Specifications

Compatibility

Direct OEM fit for the ICP / Tempstar / Heil RGS300HFFA0AAAA gas furnace and other ICP-family furnaces that share this ignition assembly. Always confirm the mounting bracket and connector match the part you are removing.

Installation Guide

1. Safety First — Shut off the gas and disconnect power at the furnace switch and breaker. 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 removal.
4. Remove — Unplug the igniter connector and remove the mounting screw(s). Handle the old igniter by the bracket only — never touch the element.
5. Install — Mount the new igniter by the ceramic base or bracket only (skin oils shorten element life), then reconnect the plug.
6. Test — Restore gas and power, start a heat call, and confirm the igniter glows and the burners light promptly.

Signs You Need a Replacement

• Furnace cycles the inducer and clicks the valve but never ignites.
• Visible crack, hot spot, or broken tip on the element.
• Repeated ignition lockouts after several retries.
• No glow visible at the igniter on a heat call.
