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 kit for the ICP / Tempstar / Heil RGS121LECA0AAA includes the igniter (part number 1171306) and the matching igniter wiring kit (part number 1188370). On a call for heat the control board sends 120V to the igniter, which glows red-hot to ignite the burners. Hot surface igniters are brittle silicon-carbide or silicon-nitride elements that degrade with every heating cycle and eventually crack or lose continuity — the most common cause of a furnace that runs the inducer and clicks the gas valve but never lights. The included wiring kit ensures a clean, corrosion-free connection so the new igniter receives full voltage. Replacing the igniter restores fast, reliable ignition and ends no-heat lockouts.
