ICP Igniter Electrode for RGS300LDAA0AAAA — OEM Part 1179966 | Ships Today

Overview

This genuine OEM igniter electrode (part number 1179966) ignites the burner gas during each heating cycle of the ICP / Heil / Tempstar RGS300LDAA0AAAA gas furnace. On every call for heat the control sends voltage to the electrode, creating the spark or surface heat that lights the main burners. A cracked, eroded, or fouled electrode is one of the most common causes of no-heat calls: the furnace cycles the inducer, attempts ignition, fails to light, and locks out. Replacing this wear item with the correct OEM electrode restores fast, dependable ignition and ends frustrating no-heat lockouts.

Installation Guide

1. Safety First — Shut off the gas, disconnect power at the furnace switch and breaker, and verify zero voltage with a multimeter.
2. Access — Remove the furnace burner/service panel to reach the burner assembly and igniter.
3. Document — Photograph the electrode position, gap, and wire routing before removal.
4. Remove — Disconnect the ignition lead, remove the mounting screw(s), and lift the old electrode out without bending the bracket.
5. Install — Seat the new electrode, restore the original gap and alignment to the burner, and reconnect the ignition lead.
6. Test — Restore gas and power, call for heat, and confirm the burners light promptly and hold flame.

Signs You Need a Replacement

• Furnace tries to ignite, fails, and locks out on a no-heat fault.
• Visible cracks in the ceramic insulator or eroded/burnt electrode tip.
• Delayed ignition with a noticeable "whoomp" at light-off.
• Repeated short cycling on ignition without a steady flame.
