Overview

The ICP hot surface igniter (OEM #606996) is the direct-replacement ignition source for the WUGB105AG01 gas furnace. On each call for heat, the furnace control board energizes this igniter, which heats to roughly 1,800–2,500°F and ignites the gas flowing from the burner manifold. A cracked, carbon-fouled, or open igniter is one of the most common causes of furnace no-heat calls. Typical failure symptoms include the furnace cycling without lighting, a glowing igniter that never sparks the burners, repeated lockouts, or no glow at all. This silicon-nitride-style igniter is rated for 120V operation and is built to OEM specification for reliable, long-life ignition.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, shut off the gas, and verify zero voltage with a multimeter.
Access — Remove the furnace burner-compartment service panel.
Document — Photograph the igniter mounting bracket and wire harness routing before disconnecting.
Remove — Unplug the igniter connector, remove the mounting screw(s), and carefully withdraw the old igniter without touching the brittle element.
Install — Mount the new igniter in the same position (handle the ceramic base only, never the element), secure the screw, and reconnect the harness per your photo.
Test — Restore gas and power, then run a heat cycle and confirm the igniter glows and the burners light promptly.
