LiftMaster K001D8395 Logic 5.0 Control Board with Current Sense
The LiftMaster K001D8395 is the updated Logic 5.0 control board used across a wide range of LiftMaster commercial door operators. It is the central control board that manages operator logic, monitored safety inputs, control station inputs, limit information, and related system functions.
This board is commonly listed as the replacement for the older K001D8075-1 and K77-37986 Logic 5 board family. It includes current sense support and is required on many three-phase Logic 5 applications manufactured after the current-sense changeover period.
K001D8395 is not the same as the voltage-specific power board. The same logic board can be used across many 1 phase and 3 phase Logic 5 operators, but the matching power board and transformer still depend on the operator voltage, phase, and enclosure build.
Compatible With / Common Applications
Commonly listed as compatible with all LiftMaster 1 phase and 3 phase Logic 5.0 commercial door operators when the existing system uses the Logic 5 control platform.
- LiftMaster Logic 5.0 1 phase commercial door operators
- LiftMaster Logic 5.0 3 phase commercial door operators
- Common model families include T, APT, H, J, HJ, GH, GT, SD, and GSD Logic 5.0 operators
- Logic 5.0 operators requiring current sense support
- Replacement path for K001D8075-1 and K77-37986 board references
- Works with voltage-specific Logic 5 power boards such as K001D8396-1, K001D8397, K001D8397-1, and K001D8398 where applicable
- Not a replacement for residential garage door opener receiver logic boards

Technician Note
This is the Logic 5 control board. If the operator has a blown power board, transformer, MOV kit, or harness problem, replacing only the logic board may not correct the issue and may damage the new board.
Before Ordering Checklist
- Confirm the operator is a LiftMaster Logic 5.0 commercial door operator
- Confirm the old board number is K001D8075-1, K77-37986, K001D8395, or an approved related reference
- Check whether the operator is 1 phase or 3 phase and uses current sense
- Inspect power board, transformer, MOV kit, and harnessing before installing the board
- Run the operator setup and safety checks after replacement
Professional Advisory
Disconnect power before accessing the electrical box. A qualified commercial door technician should diagnose the failed board, correct the cause of failure, and test all entrapment protection and stop circuits after service.
Product Questions and Answers
What does K001D8395 replace?
It is commonly listed as the replacement for K001D8075-1 and K77-37986 Logic 5.0 board references.
Is K001D8395 compatible with both 1 phase and 3 phase operators?
Yes. It is commonly listed for LiftMaster Logic 5.0 commercial operators in both 1 phase and 3 phase applications, when the operator uses the L5 control platform.
Is this the same as the power board?
No. K001D8395 is the logic/control board. The power board is a separate voltage-specific component.
Which model families commonly use this board?
Common Logic 5 families include T, APT, H, J, HJ, GH, GT, SD, and GSD, but the parts diagram should still be checked.
Does this board include current sense?
Yes. It is listed as a Logic 5.0 replacement board with current sense support.
