LiftMaster K001D8397 Logic 5 Three-Phase Power Board Kit
The LiftMaster K001D8397 is a Logic 5.0 three-phase commercial operator power board kit. It is designed for compatible LiftMaster L5 commercial operators using 230V or 460V three-phase power configurations.
The power board is a major electrical component in the operator control system. It works with the Logic 5 control board, transformer, current-sense components, motor circuits, and operator wiring to control the power side of the commercial door operator.
What This Part Does
The power board handles power-related switching and control functions in compatible three-phase Logic 5 operators. It is part of the system that allows the low-voltage logic section to control higher-voltage motor operation safely and reliably.
A failed power board may cause no motor operation, blown fuses, relay or board damage, fault conditions, intermittent operation, or incorrect response to commands. Similar symptoms can also be caused by motor problems, bad transformer, failed control board, damaged current-sense harness, incorrect voltage, or external wiring faults.
Compatible With
K001D8397 is commonly used with select LiftMaster Logic 5.0 three-phase commercial door operators using 230V or 460V configurations. Compatibility must be verified by parts diagram and wiring diagram.

Technician Note
Before replacing the power board, confirm the operator input voltage, phase, and current-sense/control-board configuration. Installing the wrong board or applying the wrong voltage can immediately damage the replacement part.
If the old board failed, inspect motor wiring, contactors/relays, current-sense harnesses, transformer output, ground faults, and surge damage before powering the new board.
Before Ordering, Confirm
- Confirm the operator is a Logic 5 three-phase unit.
- Confirm the voltage is 230V or 460V where applicable.
- Confirm the parts diagram lists K001D8397.
- Check the current-sense and control-board configuration.
- Inspect the motor circuit and wiring for faults before installation.
- Document all wiring locations before removing the old board.
Professional Advisory
This is a high-voltage commercial operator electronic part. Power-board replacement should be performed by a qualified commercial door technician. Do not bypass current-sense wiring, safety devices, interlocks, or protective circuits to force an operator to run.
