A damaged or malfunctioning circuit board is often the cause of problems with a garage door opener. If you’ve determined that your opener’s circuit board is faulty, a replacement circuit board from North Shore Commercial Door, such as this LiftMaster Chamberlain 41DJ001 circuit board, can be quickly installed in place of the old one to get your garage door opener working right again.
Circuit board 41DJ001 fits the LiftMaster 3800 jackshaft garage door opener. The circuit board comes complete with the mounting plate. Installation is a simple matter of disconnecting the unit, removing the old circuit board, mounting the new one, attaching the plug and restoring power to the unit.
Circuit boards often fail due to a lightning strike, electrical surge or other problem with the power supply, so North Shore Commercial Door recommends that you protect your new 41DJ001 replacement circuit board by installing a LiftMaster 990LM Garage Door Opener Surge Protector. We make it easy by offering a special discount price for the two items when you order the replacement circuit board and the surge protector together.
