Overview
This is the genuine OEM hot surface igniter assembly for the ICP / Tempstar / Heil WPG3482090LKB1 packaged gas/electric unit (OEM part 1175974). The igniter is the component that glows red-hot when the furnace control board calls for heat, lighting the gas at the burners. Hot surface igniters are brittle and degrade over thousands of heating cycles — they are one of the most frequent no-heat causes. The assembly ships complete with its mounting bracket and wiring harness for a direct, drop-in replacement. A cracked, broken, or aged igniter will fail to glow, leaving the unit locked out on ignition failure with no heat.

Compatibility
Factory-correct igniter assembly for the ICP / Tempstar / Heil model WPG3482090LKB1. This assembly fits many ICP-family packaged and furnace units that use the same ignition system — confirm the bracket shape and connector match your failed igniter before installing. Handle the igniter element by the ceramic base only; skin oils shorten its life.
Installation Guide
- Safety First — Disconnect power at the unit disconnect and shut off the gas supply. Verify zero voltage with a multimeter.
- Access — Remove the burner-compartment service panel to expose the igniter at the burner assembly.
- Document — Photograph the igniter's mounting position and harness connector before removal.
- Remove — Unplug the igniter harness, remove the mounting screw(s), and carefully withdraw the old igniter without touching the element.
- Install — Mount the new igniter assembly in the exact same position, holding it only by the ceramic base, and reconnect the harness per your photo.
- Test — Restore gas and power, then run a heat cycle and confirm the igniter glows and the burners light promptly.
