VERIFIED PLATFORM INFORMATION
This board family is associated with:
- DC motor garage door opener platforms
- Wi-Fi / myQ connectivity
- Security+ 2.0
- Lock-capable systems
- Yellow Learn Button
- Belt-drive, chain-drive, or wall-mount applications depending on model
Directly documented applications in this logic-board family include:
- LiftMaster WLED
- LiftMaster 8550WL
- LiftMaster 8587WL
- LiftMaster 8360WL
- LiftMaster 8500W
WLED APPLICATION
LiftMaster identifies 041D9276 specifically as an End Panel / Receiver Logic Board replacement kit for the WLED garage door opener.
The WLED is a:
- DC platform
- Battery-backup platform
- Belt-drive platform
- LED lighting platform
- Wi-Fi / myQ platform
- Lock-capable platform
8550WL APPLICATION
LiftMaster service documentation identifies:
- 8550WL
- Receiver Logic Board 050DCTWFLK
Do not confuse the 8550WL lock-capable model with the earlier non-lock 8550W configuration.
8587WL AND 8360WL APPLICATIONS
LiftMaster service documentation identifies the lock-capable versions of the 8587W and 8360W families as using the 050DCTWFLK DC Wi-Fi Lock Receiver Logic Board.
Lock-capable units are identified by:
- Model designation containing the letter L
- Two automatic garage door lock terminals
- Appropriate lock-capable logic board
Lock-capable and non-lock-capable boards are not interchangeable.
8500W APPLICATION
LiftMaster documentation identifies the 8500W wall-mount opener as using 050DCTWFLK as its replacement DC Wi-Fi logic board.
The 8500W also uses automatic garage door lock capability.
IMPORTANT:
Because 041D9276 itself is specifically documented for WLED, customers purchasing this board for another model must verify the original board number, connectors, terminal configuration, and physical layout before ordering.
OEM PART NUMBER AND CROSS-REFERENCE INFORMATION
Related numbers within this platform include:
- 041D9276
- 50DCBL5LK
- 050DCTWFLK
Later OEM replacement families include:
- 050DCTBLK
- 050DCTBLKMC
- 050DCTBFLKMC
050DCTWFLK is an older DC Wi-Fi Lock-Capable receiver logic board.
Later Bluetooth-enabled replacement boards are documented by LiftMaster for select applications.
The fact that a newer board replaces an older board does not automatically guarantee that this older 50DCBL5LK / 050DCTWFLK board can be installed in every opener originally designed for the newer Bluetooth-enabled board.
Reverse compatibility is not guaranteed.

Do not purchase this board for:
- Non-lock-capable models

- Models requiring another logic board number
- Newer platforms unless the original board and application are specifically verified
DC and AC logic boards are not interchangeable.
Lock-capable and non-lock-capable logic boards are not interchangeable.
A Yellow Learn Button alone does not confirm compatibility.
