The LiftMaster 41D7639 End Panel with all Labels, Light Socket, & Battery Door is a genuine OEM replacement assembly for select LiftMaster residential garage door openers that feature an integrated backup battery and a side-mounted lamp. This end panel replaces the original rear/side cap of the motor head, restoring the factory light socket for proper illumination and providing a secure access door to the backup battery compartment. It also includes the factory-applied identification and safety labels, making it an ideal solution when the original cover is cracked, missing, or the lamp holder has failed.
Designed as a direct-fit service part, the 41D7639 is only compatible with operators that specifically list this part number in their parts diagram or on the original panel. No programming is required because the assembly contains no control electronics; it is a mechanical/electrical housing with a pre-integrated light socket and battery door. Installation generally involves disconnecting power to the opener, removing the existing end panel and lens, transferring the lamp leads as directed, and reinstalling with the appropriate fasteners. For safe operation, use only the bulb type and wattage specified for your opener model and follow all LiftMaster service instructions. This OEM replacement is commonly searched as a LiftMaster end panel assembly, garage door opener end cover with light socket, battery door replacement, and 41D7639 compatible part for residential openers; verify compatibility by checking the parts list for your exact model number.
