Genuine LiftMaster 050DCTWF receiver logic board. Fits 8550, 8550W.
Superseded. The 050DCTWF has been replaced by the 050DCTBFMC. Order that number — it fits the same openers.

Is your logic board the problem?
The logic board is the opener’s brain — it reads the limits, the safety inputs and the radio, then drives the motor. It is also frequently blamed for faults it did not cause, so work through this before ordering.
| Symptom | Likely cause |
|---|---|
| Opener dead, no lights, no response from anything | Power first — breaker, outlet, then the board |
| Runs one direction only | Often the board, but check the limits and the safety sensors first |
| Will not close, reverses on the way down | Safety sensors, not the board. Check the LEDs on both eyes. |
| Wall button works, remote does not | The receiver half of the board, or a remote that needs reprogramming |
| Resets or reboots mid-cycle | The board, or a supply voltage problem feeding it |
| Motor hums but the door does not move | Capacitor or drivetrain, not the board |
| Burnt smell, visible scorching or a bulged capacitor on the board | The board, definitively |
Order by the number printed on the board, not by your opener model. Boards changed several times within the same model run, so two openers with identical model numbers on the cover can take different boards. Take the cover off and read the part number on the board itself.
After fitting
A replacement logic board arrives unprogrammed. You will need to reprogram every remote and keypad, and reset the travel limits and force settings before the door will work correctly. Budget twenty minutes for that, not two.
Common questions
Will this fit my opener? Check the number printed on your existing board against the part number above. If it matches, or matches one of the alternate numbers listed, it fits. If you cannot read it, send us a photo.
Do I have to reprogram my remotes? Yes. A new board has an empty radio memory. Reprogram each remote and keypad after fitting.
Is this genuine? Yes, genuine OEM. Aftermarket logic boards exist but fitment and firmware behaviour vary, and a board is not the place to economise.
Do I need to reset the limits? Yes, travel limits and force settings after any board replacement.
My opener is a Chamberlain / Craftsman. LiftMaster, Chamberlain and Sears Craftsman share the same platform, so the same boards fit across all three where the part number matches.
