Overview

This OEM hot surface igniter (Part Number 1171306) with its matched wiring kit (Part Number 1188370) is the ignition source for the ICP / Tempstar / Heil RGS121LEAA0AAAA gas furnace. On a call for heat, the control board sends 120V to the igniter, which glows red-hot and lights the burner gas. Hot surface igniters are brittle silicon-carbide or silicon-nitride elements that degrade with every cycle and eventually crack or lose conductivity. Typical failure symptoms include no heat with the blower still running, the igniter not glowing, repeated lockouts after several ignition attempts, or a hairline crack visible in the element. The included wiring kit ensures a clean, correct electrical connection and proper strain relief.
