Overview
This OEM hot surface igniter kit for the ICP / Heil / Tempstar RGS121LTAA0AAAA gas furnace includes the igniter (part number 1171306) and the matching igniter wiring kit (part number 1188370). The hot surface igniter is the heart of furnace ignition: on a call for heat, the control board sends voltage to the igniter, its element glows red-hot, and that surface lights the gas at the burners. Igniters are brittle and consumable — repeated heat cycling, hairline cracks, contamination, or simple age cause them to fail. The included wiring kit ensures a clean, correct connection and replaces brittle or heat-damaged igniter leads at the same time.

Compatibility
Built for the ICP RGS121LTAA0AAAA and used across many ICP-family RGS-series furnaces sold as Heil, Tempstar, Comfortmaker, and Arcoaire. Confirm the igniter and wiring kit part numbers against your furnace before ordering.
Installation Guide
- Safety First — Turn off gas and electrical power to the furnace. Verify zero voltage with a multimeter before proceeding.
- Access — Remove the burner compartment service panel.
- Document — Photograph the igniter position and wiring routing before disconnecting.
- Remove — Unplug the igniter harness, remove the mounting screw, and carefully withdraw the old igniter — handle only by the ceramic base, never the element.
- Install — Mount the new igniter so the element sits in the burner flame path without touching metal, then connect the new wiring kit.
- Test — Restore gas and power, start a heat cycle, and confirm the igniter glows and the burners light promptly and evenly.
Signs You Need a Replacement
- Furnace clicks but burners never light (no glow)
- Visible cracks or breaks in the igniter element
- Repeated ignition lockouts or short-cycling on a heat call
- Brittle, frayed, or heat-damaged igniter wiring
