Repair your original LiftMaster 2500 garage door opener with a replacement LiftMaster Chamberlain circuit board, part number 41A5507. A faulty circuit board is a common cause of problems with garage door operators, so if a bad circuit board is causing your opener to malfunction, installing a replacement circuit board is a quick and simple repair that is less expensive than replacing the entire unit.
This replacement circuit board, 41A5507, is identical to the circuit board with the part number 41A5507B. The final letter in the part number designates a model year revision, but the two circuit boards are interchangeable if the rest of the part number is identical.

QUESTION: We have a Chamberlin 2500 Liftmaster Professional that appears to have been installed when the house was built in 2002. For the last two months all the remotes and the wireless keypad have been working inconsistently. Sometimes they will actuate the opener to open and sometimes they will not. When the remotes will not work, we have to use the wired button to open the garage door. Why would the opener act this way and will I have to replace it? by Charles L 10/15/2015
ANSWER: My remotes stopped working, too, but hardwire still worked.<br /><br />So I bought this board, and it still doesn’t work.<br />Not sure why, because there is really nothing else it could be.<br /><br />So I am baffled.<br />There are some different variants with different last letters, so don’t assume the last letter doesn’t matter.<br /><br />Hope you have better luck than I did.<br />Andrew by Andrew C a
STAFF ANSWER: From all the details you provided I would recommend replacing the circuit board. by Taylor M a
ANSWER: We had to replace ours. The circuit board would not fix it. Ours was installed about the same time as yours. NORTH SHORE was great with their customer service. I was told that it had something to do with the radio signal interference. The opener works fine. We were experiencing the same problem you describe. Hope this helps. by William R a
