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 kit pairs the hot surface igniter (part #1171306) with its matching igniter wiring harness kit (part #1188370) for the ICP / Tempstar / Heil RGS120LFAB0AGAA gas furnace. On every heat call the control board sends line voltage to the igniter, which glows white-hot to light the burners. Hot surface igniters are brittle silicon-carbide or silicon-nitride elements that crack with age, thermal cycling, or a finger touch — and a hairline crack means no ignition and no heat. Including the wiring kit ensures the connector and leads aren't the weak link after a tough igniter replacement.
