The LiftMaster 41AC075-2A Receiver Logic Board Assembly is an OEM replacement control board for select LiftMaster residential garage door openers. As the brain of the operator, it manages the motor, integrated radio receiver for remote controls, wall control input, and safety reversing sensor circuits. Replacing a failed logic board can restore normal operation when symptoms include unresponsive remotes, intermittent operation, constant motor running, or sensor and travel control faults. This receiver logic board is designed for specific LiftMaster AC chain-drive models and is commonly used as a direct replacement part in repair, maintenance, or upgrade scenarios where the original board carries the same part number.
Verify compatibility by matching 41AC075-2A to the part number printed on the existing board or by checking the opener’s model documentation; radio frequency and learn-button color must match the original system for remotes and wireless keypads to function correctly. Installation typically involves disconnecting power, transferring the door control, safety sensor, and motor wiring to the same labeled terminals, mounting the board, reconnecting the antenna lead, and restoring power. After installation, reprogram remote controls/keypads via the opener’s Learn button and reset travel limits and force per the opener’s manual. For safety and compliance with UL 325 requirements, ensure compatible photo-eye sensors are connected and aligned before operating the door. Handle the board using ESD precautions and disconnect power before servicing. This LiftMaster receiver logic board assembly supports common residential applications and is a reliable, brand-specific replacement for restoring proper opener performance.
Compatible with LiftMaster 3575, 3585 and 3595 models
