LiftMaster Chamberlain 41AC050-2M Garage Door Opener Circuit Board

This replacement circuit board, part number 41AC050-2M, fits several LiftMaster Chamberlain and Sears Craftsman garage door openers. Because the final letter in circuit board part numbers designates a model year change, this board is identical to part number 41AC050-2 or 41AC050-2B. This replacement circuit board fits the following LiftMaster Chamberlain models: • 3280 • PD610D • PD612D • PD612KLD • 7520D • 48930D LiftMaster Chamberlain produces parts for Sears Craftsman garage door openers, so many LiftMaster parts are interchangeable with Sears Craftsman parts. This replacement circuit board will fit Craftsman units with circuit boards labeled 41AC150-2. This circuit board comes with the LiftMaster plastic panel, so for use in Sears Craftsman unit 139.53985D (315 MHz), which has the purple learn button and a light socket on panel, you will have to install the circuit board on your existing plastic panel. This is an easy swap that only involves five mounting screws. North Shore Commercial Door recommends installation of a LiftMaster 990LM Garage Door Opener Surge Protector to protect your new replacement circuit board and we make it easy by offering a special combo price for the circuit board and surge protector together.
