LiftMaster 41AC050-1M Receiver Logic Board Assembly

The LiftMaster 41AC050-1M Receiver Logic Board Assembly is an OEM replacement control board for select LiftMaster and Chamberlain residential garage door openers. This assembly serves as the “brain” of the opener, managing the motor, integrated radio receiver for remote controls, wall control inputs, photo-eye safety sensors, and the opener light. Use it to restore normal operation when a failing or damaged control board causes issues such as unresponsive remotes, erratic door movement, or sensor faults. As a direct-fit replacement, it maintains the original opener’s functionality and compatibility with the remotes and accessories intended for that specific model.

Designed for use only with opener models that specify 41AC050-1M in their parts list, this receiver logic board supports Security+ rolling code technology used by the matching remotes/keypads for those units. Installation requires disconnecting power, transferring wire leads to the corresponding terminals, and securing the board in the existing mounting location. After installation, you will need to reprogram handheld remotes and keypads via the Learn button and reset travel limits/force settings per the opener’s manual; ensure photo-eyes are correctly wired and aligned to retain safety protections. For best results, verify compatibility by matching the part number on your original board or by referencing the manufacturer’s documentation for your specific opener model. This replacement is intended for residential trolley-style openers and is not universal across all LiftMaster products.
