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 ICP hot surface igniter (OEM part number 1176919) ignites the burners on the WFMR045A036A1 gas furnace, and is paired here with the matching snap-mount gas valve assembly (OEM part number 1176929, valve N HSI snap 36J24618). On a heat call, the control board energizes the igniter to glow red-hot, then opens the gas valve so fuel ignites at the burners. A cracked or worn igniter is the single most common no-heat failure: the furnace will run the inducer and pressure-switch sequence, attempt ignition, fail to light, and lock out. The brittle silicon-nitride/carbide element is easily damaged by handling or thermal cycling. Replacing the igniter — and inspecting the gas valve — restores reliable burner ignition.

Installation Guide

Safety First — Shut off the gas supply, disconnect power at the furnace switch and breaker, and verify zero voltage with a multimeter.
Access — Remove the burner-compartment service panel.
Document — Photograph the igniter bracket, wiring, and gas valve connections before disconnecting.
Remove — Unplug the igniter lead and remove its mounting screw; handle the old element only by the ceramic base. If servicing the valve, disconnect its wiring and unthread the gas line fittings.
Install — Mount the new igniter without touching the element surface, reconnect the lead, and snap/seat the gas valve, sealing threaded joints with approved pipe compound.
Test — Restore gas and power, run a heat cycle, confirm the igniter glows and burners light cleanly, then leak-check all gas joints with soap solution.
