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 (Part No. 1177663, used with control/igniter assembly 1186861) provides the high-temperature glow that lights the burners in your ICP WPG4424090RKA1 packaged gas furnace. On a heat call the control board sends 120V to the igniter, which glows red-hot and ignites the gas as the valve opens. Igniters are brittle and degrade with every heating cycle — eventually they crack, lose resistance, or fail to reach ignition temperature. A bad igniter is the most frequent cause of no-heat lockouts. Genuine OEM replacement ensures correct resistance, fit, and reliable lights.
