My furnace will not ignite. What part is bad?

A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds. If it does not glow at all, it is cracked or burned out. If it glows weakly, it is degrading and should be replaced preventively. Average lifespan: 3 to 7 years.

Overview

This OEM hot surface igniter (part 1171306) with matching igniter wiring kit (part 1188370) is built for the ICP Tempstar Heil RGS121HFBA0AAAA gas furnace. On each heat call the control board energizes the igniter, which glows red-hot to light the burners. Hot surface igniters are brittle and have a finite life — a cracked or aged igniter is the single most common reason a furnace ignites intermittently or fails to light at all. Including the wiring kit ensures a clean, reliable connection at the igniter harness.
