Overview
The OEM hot surface igniter (part number 1179966) is the ignition electrode for the ICP Tempstar Heil RGS243SDFA0AAAA gas furnace. On a call for heat, the control board energizes this igniter, which heats until it glows and lights the gas at the burners. Because it cycles to extreme temperatures every time the furnace fires, the igniter is one of the most common wear-out parts in a gas furnace — thermal stress eventually cracks or weakens the element until it can no longer reach ignition temperature, leaving you without heat. This genuine OEM ignitor electrode matches the original specification for dependable ignition.

Compatibility
Engineered as a direct-fit replacement for the ICP Tempstar Heil RGS243SDFA0AAAA furnace and other ICP-family gas furnaces that specify OEM part 1179966.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, and shut off the gas. Verify zero voltage with a multimeter before proceeding.
- Access — Remove the furnace burner-compartment service panel.
- Document — Photograph the igniter mounting and its wire harness/connector before disconnecting.
- Remove — Unplug the igniter connector and remove the mounting screw(s). Handle the part by its ceramic base only — never touch the fragile element. Lift the old igniter out.
- Install — Position the new igniter so the element sits correctly in the burner ignition path, secure the screw(s), and reconnect the harness per your photo. Avoid touching the element with bare fingers.
- Test — Restore gas and power, then start a heat cycle. Confirm the igniter glows, the burners light, and the flame is proven.
Signs You Need a Replacement
- Furnace will not light — no heat despite a thermostat call.
- Igniter does not glow, or glows weakly/unevenly during ignition.
- Visible cracks, blistering, or breaks in the igniter element.
- Repeated failed-ignition lockouts and retry cycling.
