LiftMaster 41A5507-B Receiver Logic Board Assembly

The LiftMaster 41A5507-B Receiver Logic Board Assembly is an OEM replacement control board that restores the core functions of compatible LiftMaster residential garage door openers. As the opener’s “brain,” it manages radio reception for handheld remotes and wireless keypads, processes safety sensor (photo-eye) signals, controls the motor and lighting circuits, and supports wall control operation. The integrated Learn button enables quick programming of LiftMaster remotes and keyless entry devices using Security+ rolling code technology, helping ensure secure access while maintaining required safety features such as auto-reverse when photo-eyes are obstructed.

This board is intended as a like-for-like replacement; verify compatibility by matching the part number on your existing logic board label to 41A5507-B (also commonly listed as 041A5507-B in LiftMaster parts catalogs). Installation typically involves disconnecting power, transferring the existing wire harnesses and terminal connections to the new board, mounting it in the opener head, restoring power, and then reprogramming remote controls via the Learn button. After replacement, check and adjust travel and force settings per the opener’s manual to ensure proper operation and compliance with safety requirements. This part is not intended for models that use Security+ 2.0 systems with a yellow Learn button—always confirm system type and part number before ordering.
