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 assembly for the ICP/Tempstar/Heil WFMR045A036B3 furnace includes the igniter (part #1176919), its mounting bracket (part #1183455), and the snap-in HSI valve hardware (part #1176929, ref 36J24618). The igniter glows white-hot to light the gas at the burners on each call for heat. These ceramic elements are brittle and wear out — a cracked or worn igniter is the single most common cause of a no-heat call. Symptoms include the furnace clicking but never lighting, repeated ignition lockouts, or a glow that never reaches full brightness.
