Overview
This genuine OEM hot surface igniter kit for the ICP / Tempstar / Heil RGS121SFAA0AAAA includes the igniter element (part 1171306) and the matching igniter wiring kit (part 1188370). On a call for heat, the control board sends line voltage to the igniter, which glows white-hot to light the gas at the burners. Hot surface igniters are fragile and degrade over thousands of heating cycles — the element develops hairline cracks or simply ages until it no longer reaches ignition temperature, leaving you with a furnace that clicks but never fires. Bundling the wiring kit ensures the brittle, heat-aged leads and connector are replaced at the same time, eliminating a common hidden cause of intermittent no-heat faults.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
- Access — Remove the burner-compartment service panel.
- Document — Photograph the igniter position and the wiring connector routing before removal.
- Remove — Unplug the igniter harness, remove the mounting screw, and lift out the old igniter without touching the new element with bare fingers.
- Install — Mount the new igniter, install the new wiring kit/connector, and route leads clear of hot surfaces exactly as photographed.
- Test — Restore power, start a heat cycle, and confirm the igniter glows and the burners light within the normal sequence.
Signs You Need a Replacement
- Furnace clicks and the inducer runs but burners never light
- Visible cracks, chips, or white blistering on the igniter element
- Igniter glows weakly or not at all on a heat call
- Intermittent no-heat that worsens with melted or brittle igniter wiring
