Overview
This OEM hot surface igniter assembly (part number 1175974) is the factory ignition component for the ICP / Heil / Tempstar WPG3602115LKB1 packaged gas-electric unit. The hot surface igniter (HSI) glows red-hot when energized by the control board, lighting the burners on a call for heat. It is one of the most common wear items in a gas furnace section. A failed igniter is the leading cause of a no-heat condition: the unit will cycle, the inducer will run, but the burners never light and the system locks out. Igniters are fragile silicon-carbide or silicon-nitride elements that crack from thermal cycling, vibration, or being touched during service. This assembly ships complete with the mounting bracket and wire harness for a direct, plug-in replacement.

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/control access panel from the unit.
- Document — Photograph the igniter wiring and bracket orientation before disconnecting.
- Remove — Unplug the igniter harness from the control, remove the mounting screw(s), and withdraw the old igniter without touching the element.
- Install — Mount the new igniter assembly by the bracket only, never the ceramic element, and reconnect the harness per your photo.
- Test — Restore gas and power, initiate a heat call, and confirm the igniter glows and the burners light cleanly.
Signs You Need a Replacement
- No heat — inducer runs but burners never ignite.
- Visible crack, chip, or break in the igniter element.
