Overview
This is a genuine OEM hot surface igniter (part #1177663) for the ICP/Heil/Tempstar WPG3304040LKC1 packaged gas unit. The igniter is the heart of the furnace's ignition sequence — when the thermostat calls for heat, the control board sends 120V to the igniter, heating its silicon nitride element until it glows and lights the gas at the burners. A failed igniter is the single most common cause of a furnace that blows cold air or short-cycles in lockout. Over thousands of heating cycles the brittle element develops hairline cracks, carbon buildup, or simply burns out, breaking the ignition chain. Replacing it with the correct factory part restores reliable, on-demand heat.

Installation Guide

- Access — Remove the blower/burner access panel.
- Document — Photograph the igniter bracket and the 2-pin wiring connector before disconnecting.
- Remove — Unplug the connector, remove the mounting screw, and carefully withdraw the old igniter without touching the element.
- Install — Mount the new igniter, handling it only by the ceramic base, and reconnect the plug per your photo.
- Test — Restore power and run a full heat cycle; confirm the igniter glows and the burners light within seconds.
