Overview
This OEM ICP hot surface igniter (part #1177663) is the ceramic ignition element that lights the burners on your WPG3604130LKC1 furnace. On each heat call the control board sends line voltage to the igniter, which glows white-hot to ignite the gas as the valve opens. Hot surface igniters are a wear item — the brittle silicon-carbide or nitride element develops hairline cracks from thermal cycling and eventually fails open, leaving you with a no-heat condition even though the inducer runs and the board sequences normally. A furnace that goes through its full ignition cycle but never lights, or that locks out after several tries, almost always points to a cracked or worn igniter. Handle the element only by its ceramic base — skin oils shorten its life.

Compatibility
Direct-fit replacement for the ICP Tempstar Heil model WPG3604130LKC1 furnace and ICP-family equipment using this hot surface igniter. Match the mounting bracket and connector to your existing igniter before installing.
Installation Guide
- Safety First – Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
- Access – Remove the burner-compartment service panel.
- Document – Photograph the igniter position, bracket orientation, and wire routing before removal.
- Remove – Unplug the igniter connector, remove the mounting screw, and carefully withdraw the old element without touching the new one's ceramic surface.
- Install – Mount the new igniter by its base only, set it to the same depth and position, and reconnect the harness.
- Test – Restore power and run a heat call; confirm the igniter glows bright and the burners light promptly with no lockout.
Signs You Need a Replacement
- Furnace sequences but burners never ignite — no heat
- Igniter does not glow, or glows weak/uneven
- Visible cracks or hot spots on the ceramic element
