Overview
This genuine OEM hot surface igniter (part 1171306) with its matched wiring kit (part 1188370) is the ignition source for the ICP Tempstar Heil RGS121LSAA0AAAA gas furnace. On a call for heat the control board sends voltage to the igniter, which heats to a glowing temperature and lights the burners. The igniter element is fragile and degrades with every heating cycle, eventually cracking or failing to reach ignition temperature. Including the wiring kit ensures a clean, fully-terminated connection — old igniter leads and connectors are a frequent failure point that causes intermittent no-heat calls. Replacing both together is the reliable fix for a furnace that clicks but won't light.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter. Igniters are brittle — handle by the ceramic base only.
- Access — Remove the burner-compartment service panel.
- Document — Photograph the igniter position and the wiring/connector routing before disconnecting.
- Remove — Unplug the igniter connector, remove the mounting screw(s), and carefully withdraw the old igniter without touching the element.
- Install — Mount the new igniter, install the new wiring kit, and reconnect to the control board per your photo. Never touch the new element with bare fingers.
- Test — Restore power, start a heat cycle, and confirm the igniter glows and the burners light promptly.
Signs You Need a Replacement
- Furnace clicks/calls for heat but burners never light
- Visible crack or break in the igniter element
