The LiftMaster K001D8397-1 Power Board Kit is a genuine OEM replacement for Logic 5.0 (L5) commercial door operators configured for 575V AC input. This assembly is the primary power stage of the operator, working in tandem with the L5 control board to manage incoming line power and deliver controlled output to the motor and system electronics. It is intended for heavy-duty commercial and industrial overhead door applications where 575V service is required, helping restore reliable operation when the original power board has failed or is damaged.
Designed specifically for the L5 platform, this 575V power board kit supports compatible LiftMaster commercial door operators used on sectional doors, rolling steel doors, and other high-cycle commercial/industrial installations. Use only on operators built and labeled for 575V AC; it is not interchangeable with lower-voltage L5 power boards. Installation and service should be performed by a qualified technician with power locked out, observing high-voltage and ESD safety procedures, followed by operator commissioning and safety-device testing per LiftMaster documentation. Refer to the operator’s model-specific manual to confirm compatibility with this K001D8397-1 replacement part.
