LiftMaster 41AS050-1 Receiver Logic Board Assembly
The LiftMaster 41AS050-1 Receiver Logic Board Assembly is an OEM replacement control board designed for specific LiftMaster residential garage door openers. This assembly houses the opener’s main control circuitry and built-in radio receiver, restoring functions such as motor control, wall control response, safety sensor monitoring, and remote/keypad operation. It is intended as a direct replacement for units that originally shipped with a 41AS050-1 board; compatibility should be verified by matching the part number printed on the existing board or the opener’s parts list. This is not a universal board, and features like radio frequency and programming behavior are model-specific, so an exact part-number match is recommended for reliable performance.
Installation typically involves disconnecting power, removing the opener’s cover, transferring each wire to the same labeled terminals on the new board, and then restoring power to complete setup. After replacement, you will generally need to reprogram remote controls and keyless entry via the opener’s Learn button and reset door travel limits per the opener’s user manual. For safety, unplug the opener before service and do not adjust door springs or counterbalance hardware. The 41AS050-1 is a dependable fix for openers experiencing intermittent operation, unresponsive remotes, or logic board faults, providing a like-for-like replacement that maintains original LiftMaster functionality for compatible chain- or belt-drive residential units.
Compatible with Liftmaster 3110 and 3220 models
