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.

Overview

This OEM hot surface igniter lights the burners on your ICP, Tempstar, or Heil furnace. On a call for heat, the ignition control board sends voltage to the igniter, which glows white-hot to ignite the gas as the valve opens. Hot surface igniters are brittle and degrade with every heating cycle — a cracked or aged element causes no ignition, repeated lockouts, or short-cycling on a cold start. This listing includes OEM part numbers 1177663 (igniter) and 1186861 (igniter control board).
