Overview
This is a genuine OEM ignitor electrode (part number 1179966) for the ICP/Tempstar/Heil RGS243LRFA0AAAA gas furnace. The igniter is the component that initiates combustion at the burners on each heating call. When energized by the control board, it heats to the high temperature required to ignite the gas/air mixture. A failed igniter is one of the single most common causes of no-heat service calls. Typical failure symptoms include the furnace cycling but never lighting, repeated ignition lockouts, a cracked or visibly broken igniter element, or a control board flashing an ignition-failure fault code. Because the element is brittle, it can fail simply from age, thermal cycling, or a hairline crack that is invisible until tested.

Compatibility
Engineered as a direct-fit OEM replacement for the ICP/Tempstar/Heil RGS243LRFA0AAAA gas furnace. ICP manufactures under multiple brand labels (Tempstar, Heil, Comfortmaker, Arcoaire), so this igniter also services equivalent units built on the same platform. Always confirm the part number 1179966 against your existing igniter before installing.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, and shut off the gas supply. Verify zero voltage with a multimeter.
- Access — Remove the burner-compartment service panel.
- Document — Photograph the igniter mounting and wire routing before disconnecting.
- Remove — Unplug the igniter connector and remove the mounting screw(s). Handle the old igniter only by its ceramic base — never touch the element.
- Install — Mount the new igniter, taking care not to touch the silicon element with bare fingers. Reconnect the wiring per your photo.
- Test — Restore gas and power, then run a heat cycle and confirm the igniter glows and the burners light cleanly.
Signs You Need a Replacement
- Furnace tries to ignite but burners never light
- Repeated ignition lockout or board fault code
- Visible crack, break, or burnout on the igniter element
- No glow from the igniter during the ignition sequence
