Overview
This genuine OEM hot surface igniter assembly fits the ICP/Tempstar/Heil RGS120HTAB0AAA gas furnace and includes both the igniter element (Part No. 1171306) and the matching igniter wiring kit (Part No. 1188370). The hot surface igniter is the component that glows red-hot on a heat call so the burner gas ignites. It is the single most common furnace failure part because the brittle silicon-carbide (or silicon-nitride) element fatigues from thousands of heat-up/cool-down cycles and eventually cracks. Typical failure symptoms include a furnace that clicks and tries to light but never fires, no glow visible at the igniter during a call for heat, a furnace that locks out after several failed ignition attempts, or repeated short cycling. Replacing the igniter along with its wiring kit ensures a clean, reliable connection and avoids a callback from a chafed or melted harness.

Installation Guide
- Safety First — Shut off gas and disconnect power; verify zero voltage with a multimeter.
- Access — Remove the burner-compartment service panel.
- Document — Photograph the igniter mounting and harness routing before removal.
- Remove — Unplug the igniter harness, remove the mounting screw, and carefully withdraw the old igniter — never touch the element with bare fingers.
- Install — Mount the new igniter, route and connect the new wiring kit per your photo, holding the element only by its ceramic base.
- Test — Restore gas and power, then watch a full ignition cycle to confirm a steady glow and burner light-off.
Signs You Need a Replacement
