LiftMaster 41A5021-1HATS Receiver Logic Board Assembly

The LiftMaster 41A5021-1HATS Receiver Logic Board Assembly is a genuine OEM replacement control board that restores radio reception and core operating functions in compatible LiftMaster and Chamberlain residential garage door openers. As the opener’s central electronics, this board manages the motor, safety reversing sensors, wall control, and built‑in radio receiver, allowing you to program remotes and keypads and run normal open/close cycles. It is commonly used as a replacement when remotes no longer respond, lights flash with no movement, or the original board has failed due to age or electrical events.

This assembly is designed for select models that use the Security+ 315 MHz platform identified by a purple Learn button on the head unit. After installation, all transmitters and keyless entries must be reprogrammed via the Learn button. For best results, disconnect power before servicing, label all low‑voltage connections (wall control, sensors) before transfer, handle the circuit board with ESD care, and verify safety reversing sensor alignment and force/travel settings per the opener’s manual. The 41A5021-1HATS supports typical residential applications and is intended as a like‑for‑like replacement or upgrade within its compatible family; it is not universal and should be matched by Learn button color and platform. Always confirm model compatibility on the opener’s rating label or manufacturer documentation prior to ordering and installing.
