Overview
This is the genuine OEM hot surface igniter assembly for the ICP/Tempstar/Heil WFMR045A036B2 gas furnace. The hot surface igniter (HSI) is the component that glows red-hot to light the burners on each heating call. When voltage is applied, the silicon-carbide or silicon-nitride element reaches over 2,000°F in seconds, igniting the gas as the valve opens. This kit covers the full ignition hardware referenced for this model: OEM 1176919 (IGNITER), 1183455 (BRACKET IGNITER), and 1176929 (VALVE N HSI SNAP WR, ref 36J24618). A cracked, eroded, or carbon-fouled igniter is the single most common cause of no-heat furnace failures. The element is fragile and degrades with every ignition cycle, so periodic replacement is normal wear.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, shut the gas valve, and verify zero voltage with a multimeter.
- Access — Remove the furnace burner-compartment service panel.
- Document — Photograph the igniter wiring and bracket position before disconnecting.
- Remove — Unplug the igniter harness connector, remove the bracket mounting screw, and lift the old igniter out without touching the fragile element.
- Install — Mount the new igniter and bracket, handling it only by the ceramic base, and reconnect the harness per your photo.
- Test — Restore gas and power, then watch a full ignition cycle to confirm the igniter glows and the burners light.
Signs You Need a Replacement
- Furnace blows cold air or fails to ignite on a heat call.
- Igniter does not glow or only glows dimly.
