• The LiftMaster 050ACTBMC AC Wi-Fi Receiver Logic Board is a genuine replacement control board for select LiftMaster and Chamberlain residential garage door openers. This Bluetooth-enabled receiver logic board is designed for compatible AC belt drive and AC chain drive Wi-Fi openers using the Security+ 2.0 yellow learn button platform.

  This board controls key opener functions including remote control communication, keypad programming, wall control operation, safety sensor communication, myQ Wi-Fi connectivity, and general opener logic. It is commonly used when the opener has lost remote/keypad communication, has Wi-Fi or myQ-related board issues, or when the original logic board has failed and the parts diagram calls for the 050ACTBMC board family.

  Before ordering, always verify compatibility by checking the model number of your opener, the color of the learn button, and the part number shown in the owner’s manual or replacement parts diagram.
