Instead of replacing your garage door opener because of a faulty circuit board, replace the malfunctioning part with a replacement logic board from North Shore Commercial Door. This circuit board, part number 41A5389-1, fits the LiftMaster Chamberlain low-profile screw-drive garage door operators. It fits Security+ door openers made from 1997 to the present and is identical to the circuit board with the newer part number 41A5389-1E. Whenever you see two circuit boards that have the same part numbers except for the final letter designating the model year (such as the "E" in the 41A5389-1E part listed here), then the two parts are interchangeable.
The 41A5389-1 circuit board is also compatible with other Security+ systems from manufacturers such as Sears Craftsman, Master Mechanic and Wayne Dalton. North Shore Commercial Door has multiple options for helping you find the right part for your job. First, consult our Chamberlain LiftMaster Garage Door Opener Circuit Board Compatibility Chart to see which replacement circuit board is compatible with your garage door opener.
