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.

Overview

This OEM hot surface igniter (HSI) is the factory-spec ignition component for the ICP Tempstar/Heil WFML045A024B1 gas furnace. The igniter is a silicon-carbide element that glows red-hot when energized by the control board, lighting the burners at the start of each heat cycle. When an igniter cracks, weakens, or fails, the furnace will run its blower but never produce heat — a no-heat call. This listing includes the igniter (OEM 1176919) and the igniter mounting bracket (OEM 1183455) so the assembly mounts and aligns exactly as it left the factory.

Compatibility

Engineered for the ICP Tempstar/Heil WFML045A024B1 gas furnace. ICP-family equipment is sold under multiple badges including Heil, Tempstar, Comfortmaker, and Arcoaire, so this igniter also services equivalent models within that platform. Always confirm against your unit's part list before ordering.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, and shut off the gas supply. Verify zero voltage with a multimeter.
Access — Remove the burner-compartment service panel.
Document — Photograph the igniter position, bracket orientation, and wire routing before disconnecting anything.
Remove — Unplug the igniter connector, remove the bracket screw(s), and lift out the old igniter. Handle the new element only by its ceramic base — never touch the silicon-carbide tip.
Install — Mount the new igniter on the bracket, position it in the burner flame path per your photo, and reconnect the harness.
Test — Restore gas and power, then run a heat cycle and confirm the igniter glows, burners light, and the flame proves.
