The LiftMaster 41AS050R2M Receiver Logic Board Assembly is the OEM control brain for select LiftMaster garage door openers, restoring reliable operation when the original circuit board fails. This assembly manages core opener functions—including motor control for open/close cycles, built-in radio reception for Security+ rolling-code remote controls, wired wall control inputs, and safety reversing sensor monitoring—so your door operates smoothly and safely. It is engineered to store and process travel and force settings (as applicable to the opener model), and features a learn button for easy pairing of compatible remotes and wireless keypads.
This replacement is intended only for units that originally shipped with, or explicitly specify, part number 41AS050R2M; it is not a universal board. For best results, match the part number on your existing board sticker or in the opener’s service manual, and confirm the learn button color/remote technology to ensure compatibility with your current transmitters. Installation requires disconnecting power, transferring terminal wires to the same labeled positions on the new board, securing the assembly in the control housing, and then reprogramming remotes/keypads and resetting travel limits per the manufacturer’s instructions. After installation, verify proper operation of the photoelectric safety sensors and the auto-reverse feature per UL 325 guidelines. This genuine LiftMaster receiver logic board is a dependable replacement for residential applications where a factory-specified board is required to restore opener performance.
Compatible with LiftMaster 3240 and 3240M models
