Chamberlain Circuit Boards

Replacing your Chamberlain garage door opener’s circuit board is a simple and easy repair. All you need to do is carefully match the part number on the old circuit board of your Sears, Raynor, Chamberlain or LiftMaster operator with one from our list below. Once you’ve found the perfect match, it’s as easy as exchanging the old board with the new board. Complete the repair yourself or hire a technician to do it for you with your own supplied parts.

Your circuit board may need to be replaced if your garage door is not functioning properly. A repair technician can diagnose the problem, or you can determine that the board is not working as intended by the activity of the door. A nonfunctioning or malfunctioning door may have a bad circuit board.

The part numbers for Chamberlain circuit boards are printed on the labels of the openers. The labels are typically found on the top rear portion of the devices. Compare the number you find to our list to determine the correct replacement part. Our convenient guide makes it easy to get the right part, every time.
