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 ICP hot surface igniter (part number 1171306) ships with its matched wiring harness kit (part number 1188370) for the RGS121LRBA0AAAA gas furnace. The hot surface igniter is the glowing element that lights the burners at the start of every heat cycle. When 120V is applied, the igniter heats to roughly 1,800–2,500°F and ignites the gas as the valve opens. Igniters are brittle and have a finite number of cycles — they crack, develop hairline fractures, or simply burn out, leaving you with a furnace that runs the inducer and blower but never produces heat. Replacing the igniter (and its often-degraded wiring) restores reliable ignition.
