ICP Hot Surface Igniter for WPG3424090RKC1 — OEM Furnace Ignitor | Ships Today

Overview

This OEM hot surface igniter is the component that lights the gas burners in the ICP Tempstar Heil WPG3424090RKC1 packaged gas unit. On a call for heat, the control board energizes the igniter, which glows red-hot and ignites the gas as the valve opens. The igniter element is brittle and degrades with every heating cycle, making it one of the most common no-heat failures. Symptoms include a furnace that clicks and runs the inducer but never lights, an igniter that no longer glows, visible cracks or breaks in the element, or repeated ignition lockouts. This is an exact OEM replacement for part 1177663 — handle by the ceramic base only and never touch the element.
