ICP Hot Surface Igniter for WPG3242040RKB1 — Igniter Assembly | Ships Today

Overview

This OEM hot surface igniter assembly (P/N 1175974) is the component that lights the burners in the gas-heat section of the ICP/Tempstar/Heil WPG3242040RKB1 packaged unit. When the control board sends voltage to the igniter, its silicon-nitride element glows white-hot and ignites the gas as the valve opens. Igniters are brittle and degrade with every heat cycle, eventually cracking or losing the ability to reach ignition temperature. A failed igniter is the most common reason a furnace blower runs but produces no heat, or the unit short-cycles and locks out on failed ignition. Replacing with the exact OEM assembly restores reliable, fast ignition each cycle.
