OEM Carrier Hot Surface Igniter (Spark Electrode) for Model PY4GNAA48060AA — Part 48VL400002

This is the factory OEM spark electrode igniter (part #48VL400002) for the Carrier PY4GNAA48060AA packaged unit. The hot surface igniter is the component responsible for igniting the gas burner on every call for heat. When the control board signals a heating cycle, the igniter heats to ignition temperature — typically over 1,800°F — and lights the gas before the flame sensor confirms burner operation. When the igniter fails or cracks, the furnace or packaged unit will attempt ignition, fail to establish a flame, and enter a safety lockout. Common symptoms include no heat, repeated ignition attempts followed by a lockout fault code, or a visibly cracked or broken igniter element.
