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 is a genuine OEM hot surface igniter kit for ICP, Heil, and Tempstar gas furnaces, including the igniter (OEM #1171306) and its matching wiring kit (OEM #1188370). The hot surface igniter is energized at the start of each heat cycle, glowing red-hot to ignite the gas at the burner. The included wiring kit provides the correct harness/connector to mate the igniter to the furnace control board. Igniters are fragile and degrade over time from thermal cycling, eventually cracking or losing the ability to reach ignition temperature. Typical symptoms include no ignition, repeated lockouts, the furnace cycling on the inducer but never lighting, or an igniter that no longer glows.
