Overview
This OEM kit pairs the hot surface igniter (Part No. 1171306) with its matching igniter wiring kit (Part No. 1188370) for the ICP / Tempstar / Heil RGS120SFAB0AAA gas furnace. The hot surface igniter is the component that glows red-hot when the furnace calls for heat, lighting the gas at the burners. It is one of the most frequently replaced furnace parts because the igniter element is brittle and degrades with every heat cycle until it eventually cracks or fails to reach ignition temperature. Including the fresh wiring harness ensures the connector and leads are not the cause of intermittent or no-ignition faults. When this part fails you typically get a furnace that cycles the inducer and gas valve but never lights, ending in a lockout.

Compatibility
Designed for the ICP / Tempstar / Heil RGS120SFAB0AAA and other ICP-family gas furnaces using this hot surface igniter and connector. Confirm OEM part numbers 1171306 and 1188370 against your current igniter and harness before ordering.
Installation Guide
- Safety First - Disconnect electrical power and shut off the gas, then verify zero voltage with a multimeter before reaching into the burner area.
- Access - Remove the burner compartment door to expose the igniter at the burner.
- Document - Photograph the igniter position, mounting screw, and harness routing before disconnecting.
- Remove - Unplug the igniter harness, remove the mounting screw, and lift out the old igniter. Handle only by the ceramic base, never the fragile element.
- Install - Mount the new igniter so the element sits correctly in the burner flame path, then connect the new wiring kit per your photo.
- Test - Restore gas and power, start a heat cycle, and confirm the igniter glows and lights the burners promptly.
Signs You Need a Replacement
- Furnace runs the inducer but never ignites, then locks out
- Visible cracks or a chipped, eroded igniter element
- Igniter does not glow or glows weakly/unevenly
- Intermittent no-heat calls caused by a damaged igniter connector
