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 Igniter Electrode (part 1179966) is the hot surface ignition element that lights the burners on the ICP / Tempstar / Heil RGS243LRAA0AAAA gas furnace. On a call for heat the control board energizes the igniter, which glows hot to ignite the gas as the valve opens. Igniters are brittle and degrade over thousands of cycles; a cracked or worn igniter causes no-heat calls, ignition lockouts, and delayed or rough light-off. The factory electrode restores reliable, on-time ignition.
