Liftmaster K001D8396-1 K001D8396, K001D8072-1 Power Board 1PH Logic 5
The LiftMaster K001D8396-1 power board is the single phase power-board replacement used in select Logic 5.0 commercial door operators. In a Logic 5 operator, the power board handles the line-voltage side of the control system and works with the operator logic board, transformer, relays, and harnessing to supply and manage the control circuit. When this board is damaged, the operator may appear dead, may not energize control circuits correctly, or may show relay or board damage after a power event.
This is a voltage and phase-sensitive component. A Logic 5 commercial operator may use a different power board depending on whether it is single phase or three phase and depending on the operator configuration. The board should be replaced only after the original part number, model family, voltage, and wiring layout have been confirmed. Do not use this item as a substitute for a three phase power board, a main logic board, or a non-Logic 5 control assembly.

Technician Note
When a Logic 5 operator has no control power or visible board damage, confirm incoming voltage, branch circuit condition, transformer output, stop circuit, and harness condition before replacing the power board. Replacing a board without correcting a voltage or wiring problem can damage the new board.
Before Ordering Checklist
- Confirm the operator is a LiftMaster Logic 5.0 commercial door operator
- Confirm the operator is single phase, not three phase
- Match the original board number to K001D8396-1, K001D8396, K001D8072-1, or K001D8072
- Verify 115V or 230V application against the operator nameplate
- Compare connector layout and relay position with the original board
- Have a qualified technician handle high-voltage diagnosis and installation
Professional Advisory
Commercial door operators contain high-voltage wiring and moving door hazards. Board replacement and voltage diagnosis should be performed by a qualified commercial door technician. Do not bypass stop circuits, entrapment protection, interlocks, or monitored safety devices to make an operator run.
Product Questions and Answers
Is K001D8396-1 the same as K001D8072-1?
K001D8396-1 is commonly used as the current service number for the single phase Logic 5 power board family, while K001D8072-1 appears as an earlier or related board reference. Match the number on the original board and verify the operator parts diagram before ordering.
What operators use this Logic 5 power board?
This board is used with select LiftMaster Logic 5.0 commercial door operators that are wired for single phase 115V or 230V power. Common families to verify include T, APT, H, J, HJ, GH, GT, SD, and GSD Logic 5.0 operators.
Can this board be used on a three phase operator?
No. This listing is for a single phase Logic 5 power board. Three phase Logic 5 operators use different voltage and phase-specific power boards, so the original board number and operator nameplate must be checked.
What symptoms can point to a failed power board?
A bad power board may be suspected when the operator has confirmed incoming power but will not power the Logic 5 controls, has relay damage, shows burned board components, or has intermittent power to the control circuit. Electrical troubleshooting should be handled by a qualified commercial door technician.
Does this board include the main logic board?
No. This is the power board side of the Logic 5 control system, not the main logic board. Inspect the logic board, power board, transformer, harnessing, and incoming voltage before replacing parts.
