ICP Hot Surface Igniter for WPG3484115LKC1 — Furnace Ignitor | Ships Today

Overview

This genuine OEM hot surface igniter (part #1177663) is the ignition component for the ICP/Tempstar/Heil WPG3484115LKC1 packaged unit. On a call for heat, the control board sends voltage to the igniter, which glows orange-hot and lights the gas at the burners. Hot surface igniters are a normal wear item — the brittle silicon-carbide or silicon-nitride element degrades with every heating cycle and eventually cracks or fails to reach ignition temperature. When that happens you'll typically see the furnace lock out after several failed ignition attempts, short cycling, or no heat at all. Replacing the igniter is one of the most common no-heat repairs and restores reliable startup.

Specifications

Compatibility

Direct OEM fit for the ICP/Tempstar/Heil WPG3484115LKC1 packaged system. As the factory igniter for this model, it mounts and wires in without modification. Confirm the connector style and mounting bracket match the unit you are servicing.

Installation Guide

1. Safety First — Disconnect power and shut off the gas, then verify zero voltage with a multimeter.
2. Access — Remove the burner/service panel to expose the igniter assembly.
3. Document — Photograph the wiring and igniter position before removal.
4. Remove — Unplug the igniter harness and remove the mounting screw. Handle only by the ceramic base — never touch the fragile element.
5. Install — Mount the new igniter, reconnect the harness, and ensure the element sits properly over the burner.
6. Test — Restore gas and power, then watch a full ignition cycle to confirm the igniter glows and lights the burners.

Signs You Need a Replacement

• No heat — burners never ignite
• Furnace locks out after multiple failed ignition attempts
