ICP Hot Surface Igniter Electrode for RGS300LDEA0AAAA — OEM 1179966 | Ships Today

Overview

This is the OEM hot surface igniter electrode (part number 1179966) for the ICP / Heil / Tempstar RGS300LDEA0AAAA gas furnace. The igniter is the component that heats to a high temperature on each call for heat and ignites the burner gas. It is one of the most common wear items in a gas furnace because it is cycled and heated repeatedly. A failed igniter is the number-one cause of no-heat calls. Symptoms of failure include the furnace blower running but never producing heat, a visible crack in the igniter element, repeated lockouts, or no glow at the igniter during a heat call.

Specifications

Compatibility

Directly fits the ICP RGS300LDEA0AAAA gas furnace and is shared across many ICP-family RGS-series furnaces sold under the Heil, Tempstar, Comfortmaker, and related brand names. Always confirm the OEM number 1179966 against your existing igniter before ordering.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, and shut off the gas supply. Verify zero voltage with a multimeter.
2. Access — Remove the furnace burner/control compartment service panel.
3. Document — Photograph the igniter mounting and wire routing before disconnecting.
4. Remove — Disconnect the igniter wire harness, remove the mounting screw(s), and carefully withdraw the old igniter without touching the ceramic element.
5. Install — Mount the new igniter in the same position, handling only the ceramic base. Reconnect the harness per your photo.
6. Test — Restore gas and power, then run a heat cycle to confirm the igniter glows and lights the burners.

Signs You Need a Replacement

• Furnace blower runs but produces no heat
