Overview
The OEM hot surface igniter (part number 1179966) is the ignition electrode for the ICP Tempstar Heil RGS243SEAA0AAAA gas furnace. When a call for heat is received, the control board energizes this igniter, which glows red-hot to ignite the gas at the burners. As the most heat-stressed component in the ignition sequence, igniters are a common wear item — repeated thermal cycling eventually cracks or weakens the element until it can no longer reach ignition temperature, leaving you with no heat. This is a genuine OEM ignitor electrode that matches the original specification for reliable, repeatable ignition.

Compatibility
Engineered as a direct-fit replacement for the ICP Tempstar Heil RGS243SEAA0AAAA furnace and other ICP-family gas furnaces that specify OEM part 1179966. ICP, Tempstar, Heil, and Comfortmaker furnaces frequently share igniters across model lines. Confirm your unit calls for 1179966 before ordering to guarantee correct fitment.
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 by the ceramic base only — never touch the fragile element. Lift the old igniter out.
- Install — Seat the new igniter so the element sits in the correct burner ignition position, secure the screw(s), and reconnect the harness per your photo. Do not touch 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 proves.
Signs You Need a Replacement
- Furnace will not light — no heat despite a call from the thermostat.
- Igniter does not glow, or glows weakly/unevenly during the ignition sequence.
- Visible cracks, blistering, or breaks in the igniter element.
- Furnace tries to ignite, locks out, and repeats (failed ignition cycling).
