LiftMaster Circuit Control Boards
Replacing your Chamberlain, LiftMaster, Sears Craftsman garage door openers Receiver Logic Circuit Board is easy to install and is often the cause of a non-functioning garage door opener. Just match the 41Axxxx-xx part number found on the Logic Circuit Board of your garage door opener to one on our list below. Many boards have a letter at the end of the model number. The higher the letter the more recent the board. For example, a model 41A4252-6F is the same logic board as a model 41A4252-6G logic board. Chamberlain LiftMaster Logic Circuit boards are Sears Craftsman compatible.
You have a bad circuit board if you press the wall button or the remote and the opener just clicks and does not activate...or IF your remotes will not work and cannot be programmed...or IF your remotes only work from a short distance and you've replaced the batteries. This means the receiver, which is part of the circuit board, is weak or not functioning.
IF you press your button or remote and the motor buzzes but does not activate you either have a bad capacitor or the unit is seized. This is not a circuit board issue!
