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:







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.

QUESTION: My opener is working except I cannot increase down pressure any more and the opener is faulting from all remotes except the wall switch. Will replacing the board probably fix my issue as the rest of the unit is in great shape? by Gary T 6/23/2014
ANSWER: I am sorry I do not know the answer to your question. I had a friend replace the part and it restored full function to my garage door . by Patrick L a
ANSWER: My problem was that my opener would work sporadically from the remotes and the wall switch. I did not have an issue with the down pressure setting. The unit was in good condition and I did not want to toss it for a new one. I changed the board and everything worked fine. Mechanically the unit was working -- it was just the brains or circuit board that was not working. I am not sure what model board you are getting it has been a while since I did this, but I had to keep the original plastic housing and swap out the boards. The housing the new boards came on did not fit my opener. by Jack G a
