Overview
This OEM kit pairs the hot surface igniter, ICP part number 1171306, with its matching wiring harness kit, part number 1188370. The hot surface igniter is the component that glows red-hot at the start of each heating cycle to ignite the gas at the burners. The included wiring kit provides the correct connector and leads for a clean, reliable connection to the furnace control board. Hot surface igniters are fragile and degrade with every cycle — the silicon-carbide or silicon-nitride element becomes brittle and eventually cracks or fails to reach ignition temperature. When that happens, the furnace runs its sequence but never lights, often locking out after several failed attempts. Replacing the igniter and its harness together restores dependable ignition and avoids intermittent connector faults.

- Remove — Unplug the igniter harness, remove the mounting screw, and carefully withdraw the brittle igniter without touching the element.
- Install — Mount the new igniter handling it only by the ceramic base, then connect the new wiring harness to the control board.
- Test — Restore gas and power, call for heat, and confirm the igniter glows and the burners light within the normal sequence.
