Overview
This OEM hot surface igniter assembly is the ignition source for the ICP Tempstar/Heil WFMR045A024B1 gas furnace. The silicon carbide element (OEM part 1176919) glows to roughly 2,500°F to ignite the burner gas on each heat call, and the kit includes the dedicated igniter mounting bracket (OEM part 1183455) plus the snap-action HSI valve component (OEM part 1176929, ref 36J24618). When an igniter fails, the furnace blower may run but produce no heat, the unit will short-cycle on failed ignition lockout, or you may hear repeated clicking from the control board attempting ignition retries. Silicon carbide igniters are fragile and degrade with every heating cycle, so they are one of the most common no-heat failure points on this furnace platform.

Compatibility
Engineered as a direct OEM replacement for the ICP Tempstar/Heil WFMR045A024B1 furnace. The same igniter family is shared across many ICP-built 45,000 BTU induced-draft gas furnaces sold under the Tempstar, Heil, Comfortmaker, and Arcoaire labels. Always confirm your existing part number against 1176919 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 furnace burner/blower access panel.
- Document — Photograph the igniter wiring and bracket position before disconnecting.
- Remove — Unplug the igniter connector, remove the bracket mounting screw, and lift out the old igniter. Handle the new element by the ceramic base only — never touch the carbide.
- Install — Mount the new igniter and bracket, align it over the burner per your photo, and reconnect the plug.
- Test — Restore gas and power, then run a heat cycle and confirm the igniter glows and the burners light within the trial-for-ignition period.
Signs You Need a Replacement
- Furnace ignites intermittently or locks out on no-flame after 3 tries
- No glow visible from the igniter during a heat call
- Visible cracks, blistering, or white powder on the carbide element
- Blower runs continuously but the furnace produces only cold air
