A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds. If it does not glow at all, it is cracked or burned out. If it glows weakly, it is degrading and should be replaced preventively. Average lifespan: 3 to 7 years.

Overview

This OEM ignition replacement covers the hot surface igniter (part 1177663) and the matching control board igniter assembly (part 1186861) for the ICP / Tempstar / Heil WPG4304040RKA1 gas package unit. The hot surface igniter is a silicon-carbide or silicon-nitride element that glows red-hot when energized, lighting the burners on each heat call. It is one of the most failure-prone parts in a gas furnace because the element becomes brittle with thousands of heat cycles and eventually cracks. When the igniter fails, the burners never light and the board locks out — leaving you with no heat. Installing a fresh OEM igniter restores fast, reliable ignition.

Compatibility

Engineered as the factory ignition replacement for the ICP WPG4304040RKA1 packaged gas unit and shared across many comparable ICP, Tempstar, Heil, and Comfortmaker furnace and package models. Confirm the connector style and mounting bracket match your existing igniter before installing.

Installation Guide

Safety First — Shut off gas and disconnect power at the unit, then verify zero voltage with a multimeter.
Access — Remove the burner-compartment service panel.
Document — Photograph the igniter position, bracket, and wire routing before removal.
Remove — Unplug the igniter connector and remove the mounting screw; handle the fragile element only by its ceramic base, never the hot surface.
Install — Mount the new igniter in the exact factory position and reconnect the harness.
Test — Restore gas and power, start a heat cycle, and confirm the igniter glows and the burners light.
