ICP Hot Surface Igniter for WFML045A024A1 — Direct-Replacement HSI | Ships Today

Overview

This OEM hot surface igniter (HSI, OEM 1176919) is the factory ignition element for the ICP Tempstar/Heil WFML045A024A1 gas furnace. The silicon-carbide igniter glows red-hot when the control board energizes it, lighting the main burners at the start of each heat cycle. Igniters are a high-wear consumable: thermal cycling eventually cracks or weakens the element, producing a furnace that runs its blower but never heats. This is one of the most common no-heat failures and a fast, high-value repair.

Compatibility

Engineered for the ICP Tempstar/Heil WFML045A024A1 gas furnace and equivalent ICP-platform models sold under Heil, Tempstar, Comfortmaker, and Arcoaire badges. Confirm against your unit's parts list before ordering.

Installation Guide

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

Signs You Need a Replacement
