LiftMaster Chamberlain 41A5389-1E Garage Door Opener Circuit Board
The LiftMaster Chamberlain 41A5389-1E Garage Door Opener Circuit Board is very easy to install and program and is the perfect replacement for your malfunctioning or worn circuit board system. It is compatible with the LiftMaster Chamberlain low-profile screw-drive garage door operators. It is also suitable for Security+ door openers made from 1997 to the present and is identical to the circuit board with the newer part number 41A5389-1E. We recommend that you also purchase a surge protector to protect your board from power surges and lightening.
