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 is a genuine OEM hot surface igniter (part 1171306) for the ICP / Tempstar / Heil RGS120LTAA0AAA gas furnace, supplied with the matching igniter wiring kit (part 1188370). The hot surface igniter glows white-hot when the control board powers it, igniting the gas as it flows from the burners. It is one of the most failure-prone components in any modern furnace: the brittle silicon-carbide or nitride element cracks from thermal cycling, contamination, or rough handling, and a single hairline fracture stops ignition entirely. Including the wiring kit ensures the pigtail connector and leads are fresh, avoiding repeat no-heat calls caused by a worn harness.
