Overview

This OEM hot surface igniter kit pairs the igniter element (part 1171306) with the matching igniter wiring kit (part 1188370) for the ICP Tempstar/Heil RGS121HFBB0AAAA gas furnace. On each heat call, the control board sends 120V to the igniter, which heats to a glowing temperature and lights the burners as the gas valve opens. The igniter is one of the most common furnace failure points — the brittle silicon-carbide element cracks with age and thermal cycling. This kit includes the fresh wiring harness so you replace the connector and leads at the same time, eliminating intermittent connection faults.

Document — Photograph the igniter position and wire routing before disconnecting.
Remove — Unplug the igniter harness, remove the mounting screw, and carefully withdraw the cracked igniter.

Test — Restore power, start a heat cycle, and confirm the igniter glows bright and the burners light promptly.
