LiftMaster 41A4252-6G Receiver Logic Board Assembly

The LiftMaster 41A4252-6G Receiver Logic Board Assembly is an OEM replacement control board for select LiftMaster and Chamberlain residential garage door openers that originally shipped with this part number. As the brain of the opener, it governs the integrated radio receiver for remote controls and keypads, wall control input, safety reversing sensors, motor drive logic, and courtesy light timing. Replacing a failing logic board can resolve issues such as remotes not responding, intermittent operation, sensor faults, or lights and motor not behaving correctly, restoring reliable day-to-day performance.

This receiver logic board assembly is model-specific and should be matched by part number to ensure compatibility—verify 41A4252-6G on your current board or in the opener’s service documentation. Installation typically involves disconnecting power, transferring wires to the same labeled terminals on the new board, mounting it in the head unit, and then reprogramming remotes/keypads using the opener’s Learn function. After installation, set travel limits and test safety reversing sensors per the manufacturer’s instructions. For safety, unplug the opener before servicing, handle electronics with ESD care, confirm photo-eye alignment, and perform a full reversal test. This genuine LiftMaster replacement part is intended for residential garage door opener repair and upgrade scenarios where the original 41A4252-6G board is required.
