Overview

This OEM hot surface igniter (HSI) is the direct-fit ignition component for the ICP/Heil/Tempstar RGS121HEBB0AAAA gas furnace. The igniter is a silicon-nitride element that glows red-hot to light the burners on each call for heat. When an igniter cracks, carbons over, or loses its heat-up curve, the furnace will lock out and stop producing heat — one of the most common no-heat failures on this platform. This listing covers OEM igniter part 1171306 and its companion 1188370 wiring kit, so you receive the correct element and the harness/plug needed for a clean replacement.
