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 is a genuine OEM hot surface igniter (HSI, part number 1172533) for the ICP/Tempstar/Heil Z9MP1075B12B1 gas furnace. On each call for heat, the control board energizes the igniter, which glows red-hot to ignite the gas at the burners. The HSI is one of the most frequently replaced furnace parts because the brittle silicon-carbide or silicon-nitride element degrades with every ignition cycle and eventually cracks or fails to reach ignition temperature. A bad igniter is the leading cause of a furnace that clicks, draws, but produces no heat. This listing pairs with the related flame sensor (1172543) and gas valve (1172541) used on the same Z9MP1075B12B1 ignition system for a complete repair.

Compatibility

Built as the factory replacement igniter for the ICP/Tempstar/Heil Z9MP1075B12B1 furnace and compatible ICP-family models that use the same HSI ignition assembly. The companion flame sensor (1172543) and Honeywell VR8205S-type snap-mount gas valve (1172541) are part of the same ignition train for this model.

Installation Guide

Safety First — Shut off the gas, disconnect furnace power at the switch and breaker, and verify zero voltage with a multimeter.
Access — Remove the furnace burner-compartment door.
Document — Photograph the igniter bracket position and the ignition wire harness before disconnecting.
Remove — Unplug the igniter connector and remove the mounting screw(s). Handle the new igniter only by its ceramic base — never touch the element.
Install — Mount the new igniter at the correct depth/position over the burner and reconnect the harness per your photo.
Test — Restore gas and power, start a heat cycle, and confirm the igniter glows and burners light cleanly.
