ICP Hot Surface Igniter for WFAR100C066B1 – With Mounting Bracket | Ships Today

Overview

This OEM hot surface igniter kit (igniter #1176919 with mounting bracket #1184324) lights the burners on your ICP WFAR100C066B1 gas furnace. On a call for heat, the control board energizes the igniter, which glows white-hot and ignites the gas as the valve opens. Hot surface igniters are inherently fragile — the silicon-carbide or silicon-nitride element grows brittle with each heating cycle and eventually cracks. When it fails, the inducer and gas valve still cycle but you get no ignition, usually ending in a control lockout after several failed attempts. The included bracket positions the igniter precisely in the flame path for dependable lighting.

Specifications

Compatibility

Direct OEM fit for the ICP / Tempstar / Heil WFAR100C066B1 furnace. This igniter and bracket combination is shared across many ICP family gas furnaces using the same burner assembly. Confirm your existing igniter part number before ordering.

Installation Guide

1. Safety First – Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
2. Access – Remove the burner compartment service panel.
3. Document – Photograph the igniter position, bracket orientation, and wire routing before disconnecting.
4. Remove – Unplug the igniter connector and unscrew the old igniter/bracket. Handle by the ceramic base only — never touch the element.
5. Install – Mount the new igniter on its bracket in the same position, then reconnect the wiring per your photo.
6. Test – Restore power and run a heat cycle; confirm the igniter glows and the burners light cleanly.

Signs You Need a Replacement

• Furnace cycles but burners never ignite
• Igniter shows visible cracks or no longer glows
• Control board locks out after multiple ignition attempts
• Intermittent or delayed ignition with a soft "boom"
