Overview

This genuine OEM hot surface igniter (part number 1177663, with related control/igniter board reference 1186861) lights the gas burners on the heating side of your ICP WPG4484090RKA1 packaged gas/electric unit. On a heat call, the control board sends voltage to the igniter, which glows white-hot to ignite the gas as the valve opens. Hot surface igniters are brittle silicon-carbide or silicon-nitride elements that degrade with every cycle and eventually crack or lose conductivity. When the igniter fails, the furnace will not light, leaving you with no heat, repeated ignition lockouts, or a unit that runs the inducer and then shuts down.
