Genuine LiftMaster 050DCTBFMC receiver logic board — the current Security+ 2.0 board (yellow learn button) for LiftMaster and Chamberlain DC belt and chain drive openers with Wi-Fi and Bluetooth, built 2011 to 2022. It is the one board LiftMaster now ships for this whole family: it replaces the 050DCTWF, 050DCTBMC, 050DCTB, 041D8169, 1D8169-1, 1D8169-2 and 001D8214. If the number on your old board is any of those, this is the part.
Read the number off the old board, not the sticker on the opener. Unplug the opener, take off the light lens and the logic board end panel, and the part number is printed along the edge of the board next to the learn button. The learn button on this family is yellow. A purple, red or green learn button means a different generation — see the LiftMaster logic board cross reference.

Two boards this is not. AC openers — 8164W, 8165W, 8355W, 8365W, 8587W, 81550, 81640, 81650, 83650, Chamberlain B353, B550, C253, C2405 — take the 050ACTBMC (replaces 050ACTWF). Lock-capable DC openers — 87802, 8550WLB, 8580WLB, WLED, Chamberlain B980 — take the 050DCTBFLKMC. The older non-Wi-Fi DC openers built 2011–2016 (8160, 8360, 8550, HD920EV, B730) take the 045DCT, and the 2024-on Security+ 3.0 openers with a white learn button (6690L, 6580L, 4690L, 2100L) take the 030DCT.
Parts often replaced with it
485LM backup battery (the consumable on every battery backup model) · 041D8071-4 travel module · 041D0277-2 Wi-Fi transformer · 041D9276 logic board end panel · 041-0136 safety sensors · 893LM remote · L979M keypad
Is the board actually the problem?
The logic board is the most over-ordered part on a garage door opener. Work down this list before you buy:
| Symptom | Check first |
|---|---|
| Opener completely dead — no light, no beep, nothing from the wall button | The outlet and breaker, then the line cord and the transformer. The board is last on this list, not first |
| Light comes on but the motor does nothing, or clicks once | On these DC units the motor and travel module, then the wiring between them and the board |
| Door will not close and the opener light flashes 10 times | The safety sensors — alignment, a cut wire or a sun-blinded eye. This is never the board |
| Remotes and keypad stopped working but the wall button works | Remote batteries, then re-program them to the learn button. Only if the learn button LED never lights is the receiver on the board suspect |
| Lost its Wi-Fi or myQ connection | The router, the phone app and the Wi-Fi signal in the garage — not the board. Re-run the myQ setup from the app before ordering anything |
| Runs a few inches and reverses, or stops short of the floor | Door balance and the travel and force settings first, then the travel module. The board only after those |
| Beeps every few seconds, or runs slowly on battery | The backup battery is a consumable — replace it before suspecting the board |
| Learn button LED never lights, opener runs one way only, or it failed the night of a storm | The board. Surge damage is the single most common reason one of these is replaced |
After fitting
The replacement board arrives blank. After fitting it you will need to set the travel limits and force, program every remote, keypad and vehicle HomeLink to the new learn button, and re-test the safety reversal on a 2x4 laid flat on the floor. Wi-Fi and myQ do not carry over — delete the old opener from the myQ app and add it again as a new device.
Put the opener on a surge protector when you fit the new board. Lightning and utility surges are the most common reason a garage door opener logic board is replaced, and a new board on the same unprotected outlet is at the same risk. A plug-in surge protector rated for motors is a small cost next to a second board.
Common questions
My board says 050DCTWF. Is the 050DCTBFMC really the same?
Yes. LiftMaster discontinued the 050DCTWF and lists the 050DCTBFMC as its replacement. The new board adds Bluetooth, which makes the myQ setup easier, and drops in on the same connectors.
Will my old remotes work with the new board?
Any Security+ 2.0 remote or keypad (893LM, 891LM, 890MAX, 893MAX, 877LM, 877MAX) programs to the new yellow learn button. They will need to be re-learned; codes do not transfer from the old board.
Do I need the lock-capable version?
Only if your opener has the automatic deadbolt (the 841LM or the built-in lock on 87802 / 8550WLB / B980). Those openers need the two lock terminals on the 050DCTBFLKMC. Everything else in the list above uses this board.
