Overview

This OEM hot surface igniter is the ignition source for the ICP WPG4424090RKB1 packaged gas/electric unit. On a call for heat, the furnace control board energizes the igniter; its element glows white-hot and ignites the gas as it flows across the burners. It is one of the most common furnace failure points because the brittle element degrades with every heating cycle. When it cracks or burns out, the unit will not light — you'll hear the inducer run and the gas valve attempt to open, but no flame and a lockout fault. This listing covers OEM part numbers 1186861 (control board igniter) and 1177663 (ignitor) for the WPG4424090RKB1.

Compatibility

Installation Guide

Safety First — Disconnect power at the unit disconnect and shut off the gas supply. Verify zero voltage with a multimeter.
Access — Remove the burner-compartment service panel.
Document — Photograph the igniter routing and the wiring connector before disconnecting.
Remove — Unplug the igniter connector and remove the mounting screw(s). Handle the old igniter by the ceramic base only — never touch the element.
Install — Mount the new igniter so the element sits in the burner flame path, reconnect the plug per your photo. Do not touch the new element with bare fingers; skin oils shorten its life.
Test — Restore gas and power, run a heat cycle, and confirm the igniter glows and the burners light cleanly.

Signs You Need a Replacement
