LiftMaster 050DCTBFLKMC Receiver Logic Board — Bluetooth, DC, Lock Capable

The LiftMaster 050DCTBFLKMC is a Bluetooth-enabled receiver logic-board replacement kit for selected lock-capable DC belt-drive and chain-drive garage door openers with enhanced myQ technology. LiftMaster specifies the applicable units as manufactured after 2021 and equipped with a yellow Learn button. This is a model-specific service board, not a universal upgrade for any yellow-button opener. Match the original board label, opener model, manufacture date and lock-capable configuration before ordering so the replacement suits the complete installed system.

Compatibility — Models, Versions and Exclusions

Match the Board and Plan Recommissioning

Record the complete opener label and photograph the existing board connections before removal. Similar board numbers can identify different motor platforms or accessory support. The lock-capable designation describes an approved opener configuration; installing this board does not establish that an unrelated opener can accept a power lock. Resolve conflicting labels or previous modifications before selecting the replacement.

A board replacement can require travel setup, remote and keypad programming, and myQ reconnection according to the supplied instructions. Plan those steps while the door area can remain clear and supervised. Diagnose power, wiring and mechanical faults first, since a replacement receiver board cannot repair a damaged motor, binding door or faulty lock mechanism. Preserve the approved safety-sensor arrangement throughout the repair.

Specifications and Product Identification

Before Ordering

• Match the full board number, opener model and manufacture date.
• Verify DC operation and the supported lock-capable arrangement.
• Record accessories and the required setup or pairing steps.
• Check the door mechanism and power supply before concluding the board has failed.

Package Contents and Separate Requirements

This offer identifies the receiver logic-board replacement kit. A complete opener, motor, power lock, backup battery, remotes and safety sensors are not promised as included. Confirm the current kit inventory and any required end-panel or harness pieces for the exact opener. Bluetooth capability does not mean a phone can replace every setup step, and a board purchase does not supply an internet connection or configure a myQ account.

Safety Warnings — Read Before Installation or Service

• WARNING: Electrical service and unexpected door movement can cause serious injury. Use a trained door technician and disconnect mains and backup-battery power before opening the unit.
• Do not plug connectors into unmatched sockets or work on energized circuitry. Follow the replacement-board instructions and protect the electronics from static damage.
• Keep people and vehicles clear during travel setup. Never bypass safety sensors or increase force to overcome a mechanical problem.
• Verify lock release, travel, reversal, photo-eye response and all programmed controls before returning the opener to normal operation.

Frequently Asked Questions

Is a yellow Learn button enough to confirm fit?

No. The board reference, DC platform, date and lock-capable configuration must also match.

Does it convert an AC opener to DC?

No. It is a service board for specified DC openers.

Is the power lock included?

No power lock is promised with this board offer.

Will existing settings always remain?

Do not assume that. Follow the supplied instructions for travel setup, programming and connected-service reconnection.
