ICP Hot Surface Igniter Assembly for WPG3302040LKB1 — OEM | Ships Today

Overview

This OEM hot surface igniter assembly (PN 1175974) for the ICP/Tempstar/Heil WPG3302040LKB1 packaged gas/electric unit lights the burners on each heat call. The control board sends line voltage to the igniter, which glows red-hot to ignite the gas at the burner. Igniters are fragile and degrade over thousands of heat cycles — the silicon nitride or carbide element develops hairline cracks, hot spots, or simply burns open. A failed igniter is the single most common cause of no-heat calls, producing repeated ignition lockouts, no glow, or a system that cycles on the inducer but never lights.

Compatibility

Direct-fit OEM replacement for the ICP/Tempstar/Heil WPG3302040LKB1 packaged unit and Heil-family furnace sections using this igniter assembly.

Installation Guide

1. Safety First — Disconnect power and shut off the gas supply; verify zero voltage with a multimeter.
2. Access — Remove the burner/control access panel.
3. Document — Photo the igniter position and wiring connector before disconnecting.
4. Remove — Unplug the igniter lead, remove the mounting screw(s), and withdraw the old igniter — handle only by the ceramic base, never the element.
5. Install — Mount the new igniter assembly, confirm proper alignment over the burner, and reconnect the lead per your photo.
6. Test — Restore gas and power, call for heat, and verify the igniter glows and the burners light.

Signs You Need a Replacement

• No glow on a heat call
• Repeated ignition lockouts after the inducer runs
• Visible cracks or white hot spots on the element
