The DoorKing 4403-012 Circuit Board is a genuine OEM replacement PCB designed for DoorKing 9310 slide gate operators manufactured before the 2016 UL 325 update. This factory replacement control board restores reliable operator performance and replaces older compatible circuit boards used in pre-UL325 DoorKing systems.
Engineered by DoorKing for professional gate automation applications, the 4403-012 manages essential gate operator functions including motor control, limit operation, safety inputs, accessory connections, and programmable operating features. It provides a direct OEM solution for technicians repairing or servicing older DoorKing slide gate operators.
This control board is specifically intended for DoorKing 9310 slide gate operators and is not interchangeable with the 4402 series boards used on earlier DoorKing 9300 models. Compatibility should always be verified by operator model, revision, and manufacturing date before ordering.
Built for commercial-grade gate automation environments, the DoorKing 4403-012 is ideal for restoring operation in gated communities, industrial entrances, parking facilities, warehouses, commercial properties, and other vehicle access control installations using older DoorKing equipment.

Recommendation
Recommended for replacing a failed or damaged control board in DoorKing 9310 pre-2016 slide gate operators. Ideal for commercial gates, industrial facilities, gated communities, apartment complexes, warehouses, parking areas, office buildings, and secured vehicle entry systems using older DoorKing automation equipment.
Before installation, verify the operator model and board revision to ensure proper compatibility, as the 4403-012 is designed specifically for 9310 systems and should not be substituted for 9300-series 4402 boards.
