Overview
This OEM hot surface igniter assembly (part 1171306) with matching igniter wiring kit (part 1188370) is the exact ignition component for the ICP / Tempstar / Heil RGS121SEAB0AAAA gas furnace. The hot surface igniter (HSI) glows red-hot when the control board calls for heat, lighting the gas at the burners. It is one of the most common no-heat failure points in a furnace because the silicon-carbide or silicon-nitride element is brittle and degrades with every ignition cycle. Typical failure symptoms include the furnace blower running without heat, repeated ignition lockouts, a cracked or visibly damaged igniter element, or a unit that clicks but never lights.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter. Shut off the gas.
- Access — Remove the lower service panel to expose the burner assembly.
- Document — Photograph the igniter mounting bracket and the wiring connector before disconnecting.
- Remove — Unplug the igniter harness, remove the mounting screw, and lift the old igniter out without touching the element with bare hands.
- Install — Mount the new 1171306 igniter, route and connect the 1188370 wiring kit, and seat the bracket so the element sits in the burner flame path.
- Test — Restore gas and power, then call for heat and confirm the igniter glows and the burners light.
