The LiftMaster 041B4245-1 Line Cord is a genuine OEM replacement power cord assembly engineered for select LiftMaster residential garage door openers. It restores a safe, reliable connection to household AC power when the original cord is worn, damaged, or missing, helping maintain dependable operation and compliance with manufacturer specifications. As an original LiftMaster component from The Chamberlain Group, this replacement part is designed to fit and function correctly with compatible models that use a plug-in AC power supply in the United States.
Use the 041B4245-1 when your opener requires a factory-spec line cord replacement. Always confirm compatibility by checking your owner’s manual or parts diagram for the exact part number before ordering. Installation generally involves unplugging the opener, removing the cover, routing the new cord through the strain relief, and connecting the factory leads to the designated power input on the opener—service by a qualified technician is recommended if you are not experienced with electrical repairs. For safety, disconnect power before servicing and never operate a garage door opener with a frayed or altered cord.
