ICP Hot Surface Igniter for WPG3424090LKC1 — OEM Ignitor | Ships Today

Overview

This OEM hot surface igniter lights the burners on the ICP WPG3424090LKC1 system at the start of every heating cycle. When the control board energizes the igniter, its silicon-carbide (or nitride) element glows red-hot to ignite the gas as the valve opens. Hot surface igniters are a wear item — the brittle element cracks from thermal cycling, vibration, or even a fingerprint's oil, and a cracked igniter is the single most common no-heat failure. Symptoms include the igniter not glowing, the furnace clicking and going to lockout, or short-cycling on a failed flame-proving sequence. OEM part 1177663.

Installation Guide

2. Access — Remove the burner/control access panel.
3. Document — Photograph the igniter position, bracket, and wire routing before removal.
4. Remove — Unplug the igniter connector, remove the mounting screw, and carefully withdraw the old igniter — never touch the new element with bare fingers.
5. Install — Mount the new igniter so the element aligns with the burner flame path, then reconnect the harness per your photo.
6. Test — Restore power, call for heat, and confirm the igniter glows and lights the burners within the normal ignition sequence.
