ICP Hot Surface Igniter for WPG4484130LKA1 – Furnace Ignition | Ships Today

Overview

This OEM hot surface igniter assembly (part numbers 1186861 and 1177663) provides the ignition source for the gas burners on your ICP WPG4484130LKA1 system. On a call for heat, the igniter heats to a glowing temperature so the gas can ignite cleanly and reliably. Hot surface igniters are brittle and degrade over thousands of heating cycles, so they are a leading cause of no-heat calls. Typical failure symptoms include a furnace that cycles on the inducer but never lights, a glowing igniter that won't reach ignition temperature, or a visibly cracked or eroded element.

Compatibility

Direct OEM fit for the ICP / Tempstar / Heil WPG4484130LKA1 unit. Used across ICP-family furnaces and package units that share the same hot surface ignition system.

Installation Guide

1. Safety First – Disconnect power and shut off the gas supply, then verify zero voltage with a multimeter.
2. Access – Remove the burner compartment service panel.
3. Document – Photograph the igniter position and wire routing before disconnecting.
4. Remove – Unplug the igniter connector and remove the mounting screw(s), handling the element only by its ceramic base.
5. Install – Mount the new igniter without touching the element surface, then reconnect the harness.
6. Test – Restore power and gas, start a heat cycle, and confirm the igniter glows and the burners light.

Signs You Need a Replacement
