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 RGS121HTAA0AAAA includes the igniter (part #1171306) and the matching igniter wiring kit (part #1188370). On each call for heat, the control board sends voltage to the igniter, which glows white-hot and ignites the gas at the burners. Hot surface igniters are brittle and degrade over thousands of heating cycles — the element develops hairline cracks, draws less current, and eventually fails to reach ignition temperature, leaving the furnace blowing cold air or locking out on failed ignition. The included wiring harness ensures a clean, corrosion-free electrical connection. Replacing both together restores fast, dependable ignition.
