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 genuine OEM hot surface igniter (part 1177663) lights the burners on the ICP Tempstar/Heil WPG4484115LKB1 and pairs with the OEM igniter control board (part 1186861). On a heat call, the 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 thermal cycle — they are one of the most common no-heat failure points in modern gas equipment. The included control board governs the ignition timing, flame proving, and lockout sequence.
