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 (HSI) assembly is the direct-fit ignition component for the ICP / Heil / Tempstar X8MPN075B12A1 75,000 BTU gas furnace. The hot surface igniter (OEM #1172533) glows red-hot to ignite the burners on each call for heat, working alongside the flame sensor (OEM #1172543) that confirms a stable flame and the Honeywell VR8205S snap-mount gas valve (OEM #1172541) that meters 24V-controlled gas flow. A cracked, eroded, or no-glow igniter is the most common cause of a furnace that clicks but never lights. These are genuine OEM parts built to the exact resistance, mounting, and voltage specifications of your furnace.

Compatibility

Engineered for the ICP/Heil/Tempstar X8MPN075B12A1 furnace and its closely related variants in the X8MPN075 platform. Always confirm your model and serial label before ordering. These OEM ignition components fit the original mounting bracket and harness, so no adapters or rewiring are required.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, and shut off the gas. Verify zero voltage with a multimeter.
Access — Remove the burner compartment service panel.
Document — Photograph all wiring and the igniter/sensor/valve positions before disconnecting.
Remove — Unplug the igniter and flame sensor leads, unscrew their mounting brackets, and disconnect the gas valve wiring and union if replacing it. Handle the igniter only by its ceramic base — never touch the element.
Install — Mount the new igniter and flame sensor in the original positions, reconnect per your photos, and torque the gas valve connections to spec; leak-check with soap solution.
Test — Restore gas and power, run a heat cycle, and confirm the igniter glows, burners light, and the flame sensor proves flame within seconds.

Signs You Need a Replacement

Igniter does not glow or shows visible cracks/erosion on the element.
Furnace clicks and the inducer runs, but burners never light.
Burners light then shut off after a few seconds (weak or dirty flame sensor).
Short-cycling or repeated ignition lockouts on the control board.
