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 assembly covers the ignition components for the ICP / Tempstar / Heil WPG4424090LKB1 package gas/electric unit, including the ignitor (part number 1177663) and the igniter control board (part number 1186861). On a call for heat, the control board sequences the inducer and then sends voltage to the hot surface igniter, which glows red-hot to light the main burners. The igniter is the most failure-prone part in a gas heat cycle because the silicon-carbide or silicon-nitride element is brittle and degrades with every heat cycle. A cracked igniter or a board that no longer energizes it is the classic cause of a furnace that clicks, runs the inducer, but never lights.

Installation Guide

Safety First — Disconnect power and shut off the gas supply, then verify zero voltage with a multimeter.
Access — Remove the burner access and control panels.
Document — Photograph the igniter mounting and all board wiring before disconnecting.
Remove — Unplug the igniter connector and remove its mounting screw; handle the fragile element only by its ceramic base, never the hot surface.
Install — Mount the new igniter so it aligns with the burner flame path, then reconnect the control board wiring per your photo.
Test — Restore gas and power, call for heat, and confirm the igniter glows and the burners light within the trial-for-ignition period.
