Liftmaster 050DCTB Receiver Logic Control Board - Replaces 50DCTWF / 1D8169-1
The LiftMaster 050DCTBFMC is a Bluetooth-enabled receiver logic board replacement kit used in select LiftMaster and Chamberlain DC belt drive and chain drive garage door openers. The receiver logic board is the main electronic control board for the opener. It manages remote-control reception, Security+ 2.0 programming, myQ-related communication on supported models, motor control commands, travel setup, and safety-device response.
This board is part of the DC motor, yellow learn button opener family and is not interchangeable with AC motor receiver boards. Many of these opener housings look similar from the outside, so the safest way to order is to compare the original board label, opener model number, production date, learn button color, and parts diagram. If the opener has lock capability, a camera model, or a different board suffix, verify the exact board before ordering.
