Overview

This is a genuine OEM hot surface igniter (HSI), part number 1172533, for the ICP Tempstar Heil X9MPD075F12B3 gas furnace. On a call for heat, the control board energizes the igniter, which glows red-hot to ignite the gas at the burners. The silicon-carbide/silicon-nitride element is brittle and degrades with each heating cycle, making it one of the most common furnace failure points. A cracked or worn igniter causes no-heat calls, repeated ignition lockouts, or a furnace that cycles the inducer and gas valve but never lights. This igniter works alongside the matching flame sensor (1172543) and snap-mount gas valve (1172541, VR8205S) in this model's ignition system.

Compatibility

Engineered for the ICP Tempstar Heil X9MPD075F12B3 gas furnace. The 1172533 HSI is shared across many ICP-family (Tempstar, Heil, Comfortmaker, Arcoaire) furnace platforms using the same ignition module. Verify the igniter plug and mounting bracket match your existing part before ordering.

Installation Guide

Safety First — Shut off gas and disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter.
Access — Remove the burner-compartment service panel.
Document — Photograph the igniter bracket position and wiring harness routing.
Remove — Unplug the igniter connector and remove the mounting screw. Handle the element only by its ceramic base — never touch the silicon element.
Install — Mount the new igniter in the same position, reconnect the harness, and confirm proper clearance to the burner.
Test — Restore gas and power, then watch a full ignition cycle to confirm the igniter glows and lights the burners.

Signs You Need a Replacement

Furnace will not light — no glow at the igniter on a heat call
Visible cracks, chips, or fractures in the igniter element
Repeated ignition lockouts after several failed trials
