ICP Hot Surface Igniter for WPG3242040LKB1 — OEM 1175974 | Ships Today

Overview

This OEM hot surface igniter assembly (OEM part 1175974) is the component that lights the gas burners on your ICP/Tempstar/Heil WPG3242040LKB1 unit. On a call for heat, the control board sends voltage to the igniter, which glows to ignition temperature and lights the burners as the gas valve opens. Igniters are brittle silicon-carbide or silicon-nitride elements that degrade with every heating cycle, so they are among the most frequently replaced furnace parts. Common failure symptoms include no ignition, a furnace that clicks but never lights, repeated lockouts after several failed ignition attempts, and a visibly cracked or burned-out igniter element.

Compatibility

Installation Guide

2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the igniter position and wiring before disconnecting.
