ICP Igniter for WPG4604115LKA1 — Hot Surface Ignitor | Ships Today

Overview

This OEM hot surface igniter (ignitor part 1177663, used with control board igniter assembly 1186861) lights the burners on the ICP Tempstar Heil WPG4604115LKA1 packaged gas/electric unit. On a heat call, the control board energizes the igniter, which glows to roughly 2,000°F and ignites the gas as it leaves the manifold. Hot surface igniters are brittle silicon-carbide or nitride elements that degrade with every heating cycle and eventually crack or lose conductivity. A failed igniter is the single most common cause of furnace no-heat: the inducer runs and the gas valve opens, but with no ignition source the burners never light and the control locks out.

Specifications

Compatibility

Designed for the ICP Tempstar Heil WPG4604115LKA1 packaged unit and related ICP-family equipment using this hot surface igniter. Confirm the 1177663 / 1186861 part numbers and the connector style before installing.

Installation Guide

1. Safety First — Disconnect power at the unit disconnect and verify zero voltage with a multimeter.
2. Access — Remove the service panel to reach the burner assembly and igniter.
3. Document — Photograph the igniter position and wiring routing before disconnecting.
4. Remove — Unplug the igniter connector and remove the mounting screw(s); handle only by the ceramic base, never the fragile element.
5. Install — Mount the new igniter without touching the element, align it to the burner, and reconnect the plug.
6. Test — Restore power, start a heat call, and confirm the igniter glows and the burners light and stay lit.

Signs You Need a Replacement

• Furnace runs the inducer but burners never ignite (no-heat)
• Visible crack, blister, or break in the igniter element
