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 RGS120LSAA0AAA gas furnace includes the igniter (part 1171306) and the matching igniter wiring kit (part 1188370). On each heat call, the control board sends voltage to the igniter, whose silicon-carbide or nitride element glows red-hot to light the burners. These igniters are brittle and degrade with every cycle, eventually cracking or losing the ability to reach ignition temperature. Common failure signs are no heat, the blower running with cold air, repeated ignition lockouts, or a furnace that clicks but never lights. The included wiring kit ensures a clean, corrosion-free electrical connection.
