The 041DJ003MC Receiver Logic Board is a genuine LiftMaster/Chamberlain OEM replacement control board for DC-powered, Wi‑Fi–enabled RJO (Residential Jackshaft Operator) wall-mount garage door openers. It manages the operator’s core functions—including motor control, limits, safety sensors, and accessory inputs—while providing integrated wireless connectivity for Security+ 2.0 remotes and myQ smart control. Use this board to restore proper operation and connectivity when the original logic board has failed or been damaged, ensuring that your RJO opener continues to support features like remote operation, smartphone monitoring, and secure radio reception.
This DC receiver logic board is designed for LiftMaster/Chamberlain RJO-series openers with built-in Wi‑Fi, commonly used on residential wall-mount models such as the RJO20. It supports Security+ 2.0 tri‑band radio controls and keypads and is intended for units that connect to myQ over 2.4 GHz home networks (refer to your opener’s manual for network and setup requirements). Installation requires disconnecting power, swapping the board, reconnecting wire harnesses, and then reprogramming travel limits, force settings, remotes, keypads, and myQ. For safety, ensure photoelectric safety sensors are correctly aligned and perform a full reversal test after setup. Always verify compatibility by matching 041DJ003MC to your opener’s model and parts list; it is not interchangeable with boards for non‑Wi‑Fi or AC‑motor units.
