Heil Hot Surface Igniter Electrode for RGS300HTFA0AAAA — Direct-Spark Ignition | Ships Today

Overview

This OEM igniter electrode (part 1179966) is the component that ignites the gas at the burner in your ICP / Tempstar / Heil RGS300HTFA0AAAA furnace package unit. On an ignition cycle the control board energizes the electrode to create the spark/heat that lights the main burner; the same assembly is also used by the control to confirm flame. When the electrode cracks, fouls, or wears out, the furnace will lock out on failed ignition — you'll typically hear the gas valve open and the inducer run, but no flame, followed by a retry-and-lockout sequence. Replacing this inexpensive wear part restores reliable heating and prevents nuisance no-heat calls during cold weather.

Specifications

Compatibility

Direct-fit replacement for the ICP/Heil/Tempstar RGS300HTFA0AAAA model and related RGS-series gas package units using the same burner assembly. Confirm the mounting bracket and lead orientation match your existing electrode.

Installation Guide

1. Safety First — Shut off the gas at the valve and disconnect electrical power; verify zero voltage with a multimeter.
2. Access — Remove the burner compartment / service panel.
3. Document — Photograph the electrode position and wire routing before removal.
4. Remove — Disconnect the ignition lead and unfasten the electrode mounting screw(s), then withdraw the old electrode.
5. Install — Seat the new electrode at the correct gap to the burner, fasten the bracket, and reconnect the lead.
6. Test — Restore gas and power, run a heat cycle, and verify clean ignition on the first try.

Signs You Need a Replacement

• Furnace locks out with no flame after the inducer and gas valve activate
• Visible cracks, carbon buildup, or corrosion on the electrode
• Delayed ignition or a small "poof" at light-off
• Repeated ignition retries before lockout on a heat call
