Overview
This is a genuine OEM hot surface igniter (part number 1177663), used with the integrated ignition control board (part number 1186861), for the ICP / Heil / Tempstar WPG4484130RKA1 packaged gas unit. The hot surface igniter is an electrically heated silicon element that glows red-hot to ignite the burners on a call for heat. When the control board proves the inducer and pressure switch, it sends line voltage to the igniter; once it reaches ignition temperature, the gas valve opens and the burners light. Hot surface igniters are brittle and degrade with every heating cycle, eventually cracking or losing the ability to reach temperature. A failed igniter is the single most common cause of a furnace that runs the inducer but never produces heat, or that locks out after several failed ignition attempts.

Compatibility
Direct OEM replacement for the ICP / Heil / Tempstar WPG4484130RKA1 packaged gas system. The igniter is shared across many ICP-family Heil, Tempstar, Comfortmaker, and Arcoaire furnaces and packaged units. Handle the silicon element only by its ceramic base and confirm the mounting bracket and plug match your original.
Installation Guide
- Safety First — Disconnect power at the unit and verify zero voltage with a multimeter before servicing.
- Access — Remove the burner-compartment service panel.
- Document — Photograph the igniter position, bracket, and harness plug before removal.
- Remove — Unplug the igniter harness and remove the mounting screw, lifting the old igniter out without touching the element.
- Install — Set the new igniter in the same position, secure the bracket, and reconnect the harness — handling only the ceramic base.
- Test — Restore power, start a heat call, and confirm the igniter glows and the burners light within the trial period.
Signs You Need a Replacement
- Inducer runs but the igniter never glows.
- Furnace locks out after repeated failed ignition attempts.
- Visible crack, blister, or break in the silicon element.
