LiftMaster 41DB001-1C Receiver Logic Board Assembly

The LiftMaster 41DB001-1C Receiver Logic Board Assembly is a genuine OEM replacement control board designed for select LiftMaster residential garage door openers. This board serves as the “brain” of the opener—managing the built‑in radio receiver for remote controls and keyless entry, monitoring the safety reversing sensors, driving the motor, and storing programming such as remote IDs and travel limits. It’s commonly used to restore normal operation when an opener stops responding to remotes, shows diagnostic LED fault codes, or experiences intermittent performance after power surges or lightning. As a direct replacement part, it retains factory performance and compatibility with the opener’s wall control, safety sensors, and compatible LiftMaster/Chamberlain Security+ accessories (match to your opener’s technology and learn-button style).

Installation typically involves disconnecting power, removing the original board, transferring the existing low‑voltage wiring to the same labeled terminals, installing the replacement logic board, and then reprogramming remotes and travel limits using the opener’s Learn button and standard LiftMaster procedures. Always verify the exact part number printed on your existing board or consult the opener model’s parts list to confirm compatibility, as receiver logic boards are not universal across all generations or frequencies. For safety, disconnect power before service, ensure the photoelectric safety sensors are correctly wired and aligned, and perform a full safety reversal test after programming. This authentic LiftMaster receiver logic board assembly provides a reliable repair solution for select Security+ openers in residential applications, helping restore dependable door control and remote operation.
