Overview
This OEM hot surface igniter kit is the genuine ignition assembly for the ICP / Tempstar / Heil WFMR135D066B3 gas furnace. The kit centers on igniter part 1176919, supported by mounting bracket 1183455 and HSI snap-fit valve/igniter assembly 1176929 (36J24618). When the thermostat calls for heat, the furnace control board energizes the hot surface igniter, which glows to roughly 2,000°F and ignites the gas at the burners. Over time the brittle silicon-carbide or silicon-nitride element develops hairline cracks and stops glowing — the most common cause of a furnace that clicks, draws air, but never lights. Replacing the igniter with the correct OEM part restores reliable first-try ignition and prevents repeated lockouts.

Compatibility
Engineered as a direct-fit replacement for the ICP-family WFMR135D066B3 gas furnace and is shared across the Tempstar, Heil, and Comfortmaker variants built on the same chassis. Always confirm your existing igniter part number and bracket orientation before installing.
Installation Guide
- Safety First — Shut off gas and disconnect electrical power at the furnace switch and breaker. Verify zero voltage with a multimeter.
- Access — Remove the furnace burner/service panel.
- Document — Photograph the igniter wiring, connector, and bracket position before disconnecting anything.
- Remove — Unplug the igniter connector, unscrew the mounting bracket, and carefully withdraw the old igniter — handle by the ceramic base only, never the fragile element.
- Install — Mount the new igniter and bracket in the exact original position, ensuring the element sits in the burner flame path without touching metal. Reconnect the wiring per your photo.
- Test — Restore gas and power, then run a heat cycle and confirm the igniter glows and the burners light within seconds.
Signs You Need a Replacement
- Furnace inducer runs but burners never ignite (no-heat lockout).
- Igniter no longer glows orange/white during a heat call.
- Visible cracks, chips, or white powder on the igniter element.
- Repeated ignition retries or short-cycling on the control board.
