Overview

This OEM hot surface igniter (HSI) is the direct ignition component for the ICP/Tempstar/Heil RGS121HDBA0AAAA gas furnace. Replaces OEM part number 1171306 (IGNITOR) and includes the matching 1188370 igniter wiring kit so you can replace the harness leads in the same service call. The hot surface igniter glows to roughly 2,000°F when energized by the control board, lighting the burner gas on each heat call. When an igniter cracks, ages, or contaminates, the furnace fails to ignite, short cycles on ignition lockout, or rumbles on a delayed light. This silicon-nitride-style igniter is brittle by design — handle it only by the ceramic base, never the glow element.
