A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds.

Overview

This OEM hot surface igniter is the component that lights the burners in your ICP WPG4364090RKB1 gas package unit. On a call for heat, the ignition control board sends voltage to the igniter, which glows red-hot and ignites the gas as the gas valve opens. Hot surface igniters are brittle and wear out from thousands of heat cycles — the silicon carbide or nitride element develops hairline cracks, drifts out of resistance range, or shatters from handling. A failed igniter is the single most common cause of a no-heat call: the inducer runs, but the burners never light and the board locks out. This listing covers the igniter (1177663) and the matching ignition control board (1186861) for a complete repair.

Installation Guide

Access — Remove the burner compartment and control panel covers.
Document — Photograph the igniter mounting and all control board connections before disconnecting.
Remove — Unplug the igniter lead and unscrew the igniter bracket; handle the element by the ceramic base only — never touch the glow element.

Test — Restore gas and power, call for heat, and confirm the igniter glows and the burners light cleanly.
