ICP Hot Surface Igniter for WPG3484115RKC1 — OEM 1177663 | Ships Today

Overview

This OEM hot surface igniter (part number 1177663) is the ignition component for the ICP/Tempstar/Heil WPG3484115RKC1 packaged gas/electric unit. The igniter glows to a high temperature when energized by the control board, lighting the gas at the burners on each heating call. Igniters are a common wear item — repeated heating and cooling cycles cause the silicon carbide or silicon nitride element to become brittle and eventually crack. When the igniter fails you will typically see no heat, a furnace that locks out after several failed ignition attempts, or a unit that runs the inducer and then shuts down without firing.

2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter bracket position and wiring before disconnecting.
4. Remove — Unplug the igniter harness, remove the mounting screw(s), and carefully withdraw the old igniter without touching the element.
