Overview
This genuine OEM hot surface igniter (ignitor part 1177663) lights the burners on the gas heat section of the ICP / Tempstar / Heil WPG4364060LKB1 packaged unit, and pairs with the matching igniter control board (part 1186861) that sequences and powers the ignition. On a call for heat the control board energizes the igniter; it glows white-hot to ignite the gas as the valve opens. Hot surface igniters are brittle silicon-carbide or silicon-nitride elements that crack from age, thermal cycling, or being touched with bare fingers — and a cracked igniter is the single most common no-heat failure on this style of furnace. Symptoms include the inducer and igniter sequence starting but no flame, or a hard lockout after several failed ignition attempts.

Installation Guide

- Access — Remove the burner / control access panel to reach the igniter at the burner assembly.
- Document — Photograph the igniter bracket position and the plug connection before removing anything.
- Remove — Unplug the igniter harness and unscrew the bracket; handle the old igniter by the ceramic base only.
- Install — Mount the new igniter by its ceramic base — never touch the element — align it over the burner, and reconnect the harness per your photo.
- Test — Restore power and gas, start a heat cycle, and confirm the igniter glows and the burners light cleanly.
