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 OEM hot surface igniter (part number 1009524) ignites the burners on your ICP VNK050F12A1 gas furnace and also serves as the flame-sensing element on this integrated igniter/sensor design. On each heat call, the control board energizes the silicon nitride igniter until it glows hot enough to light the gas; it then confirms a flame is present. When the igniter cracks, weakens, or fails, the furnace will not light — you may hear the inducer and gas valve cycle but get no flame, or the unit may lock out after several failed ignition attempts. Cracked igniters, carbon buildup, and normal age-related wear are the most common failure causes.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
Access — Remove the furnace burner-compartment service panel.
Document — Photograph the igniter position, bracket, and wire connector before disconnecting.
Remove — Unplug the igniter connector and remove the mounting screw; handle the old igniter by its ceramic base only.
Install — Mount the new igniter without touching the silicon nitride element, then reconnect per your photo.
Test — Restore power and run a heat cycle; confirm the igniter glows, lights the burners, and the flame stays lit.
