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 assembly for the ICP/Tempstar/Heil RGS121SRBA0AAAA gas furnace, supplied with the matching wiring kit. The kit includes the hot surface igniter (part number 1171306) and the igniter wiring harness kit (part number 1188370). On each call for heat the control board sends voltage to the igniter, which glows red-hot to light the burners. Because the igniter element is brittle and degrades with every heating cycle, it is one of the most frequently replaced furnace parts. A cracked or aged igniter is the leading cause of no-heat calls where the inducer runs but the burners never light.
