My furnace will not ignite. What part is bad?

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 hot surface igniter (part #1177663, used with control/igniter assembly #1186861) is the heating element that glows red-hot to ignite the gas burners on your ICP WPG4304040LKA1 packaged gas/electric unit. On each heat call, the control board energizes the igniter; once it reaches ignition temperature the gas valve opens and the burners light. Hot surface igniters are brittle and degrade with every cycle — they crack, develop hairline fractures, or simply burn out. When the igniter fails, the unit goes through its inducer and pre-purge sequence but never lights the burners, often locking out after several failed attempts. A no-heat call where the inducer runs but no flame appears is the classic symptom.

Compatibility

Designed for the ICP WPG4304040LKA1 packaged gas/electric unit and shared across many ICP-family furnaces and packaged units (Tempstar, Heil, Comfortmaker, Arcoaire) using the same hot surface ignition system. Match the igniter mounting and connector to your original before ordering.

Installation Guide

Safety First — Disconnect power at the breaker and switch off the gas supply, then verify zero voltage with a multimeter.
Access — Remove the burner-compartment service panel.
Document — Photograph the igniter position and its wiring connector before disconnecting.
Remove — Unplug the igniter harness and remove the mounting screw(s). Handle the new igniter only by its ceramic base — never touch the silicon-carbide element with bare fingers.
Install — Position the new igniter so it sits in the burner flame path, secure the mounting screw, and reconnect the harness per your photo.
Test — Restore gas and power, then run a heat call and confirm the igniter glows and the burners light promptly.
