Overview

This genuine OEM hot surface igniter (part #1171306), with matching igniter wiring kit (part #1188370), provides reliable ignition for the ICP/Tempstar/Heil RGS121HSCB0AAA gas furnace. On a heat call, the control board energizes the igniter, which glows red-hot to light the burner gas. Igniters are a wear item — repeated heating cycles eventually crack the element or cause it to lose continuity, producing the classic no-heat / no-ignition fault. The included wiring kit refreshes the connector and leads so a brittle, heat-damaged harness doesn't fail again right after the new igniter goes in.
