Overview

This OEM hot surface igniter (HSI) is the direct-fit ignition component for the ICP/Heil/Tempstar RGS121HEBA0AAAA gas furnace. The silicon-nitride element glows red-hot on each heat call to light the burners. When the igniter cracks, carbons over, or drifts out of its heat-up range, the furnace locks out and produces no heat — the single most common no-heat failure on this platform. This listing includes OEM igniter part 1171306 and its matching 1188370 wiring kit, giving you the correct element plus the harness and plug for a clean, reliable replacement.
