Overview
This OEM hot surface igniter (ICP part #1171306) with matching wiring kit (#1188370) is the component that lights the burners in your ICP / Heil / Tempstar RGS120LDAA0AAA gas furnace. On a call for heat, the control board sends voltage to the igniter, which glows orange-hot to ignite gas at the burner. Igniters are a wear item — repeated heating and cooling cycles make the brittle silicon-nitride or carbide element crack and fail. The included wiring harness kit replaces the heat-fatigued connector and leads that are a frequent secondary failure point. When the igniter fails, the furnace draft inducer and gas valve may sequence normally, but the burners never light and the unit locks out — leaving you with no heat.

Compatibility
Direct OEM fit for the ICP / Heil / Tempstar RGS120LDAA0AAA gas furnace. The bundled wiring kit ensures the connector and leads match the furnace harness, avoiding the splice failures common with universal igniters. Verify the mounting bracket orientation against your existing igniter before installing.
Installation Guide
- Safety First — Turn off gas and disconnect electrical power; verify zero voltage at the igniter leads with a multimeter.
- Access — Remove the furnace burner-compartment door.
- Document — Photograph the igniter position, bracket angle, and wiring routing before disconnecting.
- Remove — Unplug the igniter harness, remove the mounting screw, and carefully withdraw the old igniter without touching the new element with bare fingers.
- Install — Mount the new igniter, install the supplied wiring kit, and route leads clear of the burner flame path.
- Test — Restore gas and power, call for heat, and watch for a clean glow and reliable burner ignition.
Signs You Need a Replacement
