LiftMaster K41-0575-000 TECHNA Main and Motor Drive Board Service Kit
LiftMaster K41-0575-000 TECHNA Main and Motor Drive Board Service Kit
The LiftMaster K41-0575-000 is the TECHNA service kit containing both the main control board and motor drive board for the documented barrier-arm operator platform. Use this kit when either board requires replacement, and replace both boards together as directed for the service package. The TECHNA manual identifies the set for PBG24DCW, PBG24DCG, CBG24DCW and CBG24DCG models. Match the installed operator and current service instructions before ordering; this is a coordinated electronics repair, not a complete motor assembly or a universal replacement for other LiftMaster gate boards.
Compatibility — Models, Versions and Exclusions
| Model or selection point | Compatibility requirement |
|---|---|
| PBG24DCW / PBG24DCG | TECHNA manual identifies this main-and-drive board set. |
| CBG24DCW / CBG24DCG | TECHNA manual identifies the same service-set reference. |
| Failure of either board | Use the coordinated kit and replace both boards together. |
| Other TECHNA models or revisions | Verify current manufacturer service guidance before ordering. |
| Other LiftMaster gate-board families | No universal interchangeability based on brand or DC operation. |
Diagnose the System Before Replacing the Board Pair
A barrier that stops responding can have a supply, battery, connection, motor, detection or mechanical problem. Have the technician record symptoms and diagnostic information before choosing the repair. Replacing electronics cannot correct a damaged arm, binding mechanism or unresolved wiring fault. Check the surrounding system so the condition that prompted service is addressed along with any failed board.
Treat the two boards as one service replacement. Do not keep the old companion board in place simply because it appears to operate. Record the existing wiring and settings, then follow the current kit and model instructions for installation and setup. Confirm the prescribed arm travel, operating settings and detection behavior before opening the lane to normal traffic.

Before Ordering
- Record the full TECHNA model and installed board identification.
- Confirm K41-0575-000 in the applicable service information.
- Diagnose power, motor, wiring, detection and mechanical condition.
- Plan replacement of both boards and the required setup and operating tests.
Package Contents and Separate Requirements
The kit includes the main control board and motor drive board. A motor, barrier arm, counterbalance parts, batteries, complete harness, external detector and operator cabinet are not promised as included. Verify any supplied mounting or connection pieces against the current carton instructions. This two-board inventory is the key distinction from an individual-board offer; order the service set when either of the documented boards needs replacement.
Safety Warnings — Read Before Installation or Service
- WARNING: A barrier arm can move unexpectedly and strike a person or vehicle. Electrical and mechanical service requires a qualified barrier-gate technician and a controlled work area.
- Disconnect mains power and battery backup as directed before opening connections. The arm and counterbalance mechanism can retain mechanical energy after electrical isolation.
- Replace both boards together. Do not bypass detection or protection inputs to force operation, and do not use electronics changes to compensate for a binding arm.
- Restore covers and complete the manufacturer setup and safety tests before normal traffic. Keep pedestrians out of the vehicular barrier lane and provide the required separate pedestrian route.
Related Products and Important Differences
- LOOPDETLM loop detector — listed in the TECHNA manual for plug-in vehicle-loop detection; verify the installed expansion arrangement and required loop wiring.
- LMRRUL monitored photo eye — listed among TECHNA safety accessories; install and test it for the required protection location. Neither accessory is included in this board kit.
Frequently Asked Questions
Can I replace only the main board?
The service package directs replacement of both boards together, even when only one is being replaced for a fault.
Does this kit include the motor?
No motor is promised; the motor drive board is an electronic component.
Will it fit every LiftMaster DC gate operator?
No. Match the documented TECHNA model and service reference.
Is the repair complete as soon as the boards are connected?
No. Complete the required setup, diagnostics and operating tests before returning the lane to use.
