Overview
This genuine OEM hot surface igniter (ICP part 1177663) lights the main burners on your ICP / Tempstar / Heil WPG3604115LKC1 packaged gas-electric unit. On a heat call, the control board sends 120V to the igniter element, which glows to roughly 2,000°F and ignites the gas as the gas valve opens. Igniters are a wear item — repeated heating and cooling cycles eventually crack or weaken the silicon-carbide or silicon-nitride element. A failed igniter is the most common cause of no-heat conditions: the inducer runs, you may hear the gas valve click, but the burners never light and the unit locks out. Replacing the igniter at the first sign of weakness restores reliable ignition and prevents nuisance lockouts on cold mornings.

Compatibility

Installation Guide

- Access — Remove the burner/control access panel.
- Document — Photograph the igniter position, bracket, and wiring connector before removal.
- Remove — Unplug the igniter connector and remove the mounting screw; lift the fragile element straight out without touching the carbide surface.
- Install — Mount the new igniter (handle by the ceramic base only), align it over the burner, and reconnect the plug.
- Test — Restore power, start a heat call, and confirm the igniter glows and the burners light promptly.
Signs You Need a Replacement

- Visible cracks, chips, or white spots on the igniter element.
