LiftMaster 41DB002-2 Receiver Logic Assembly

The LiftMaster 41DB002-2 Receiver Logic Assembly (also referenced by some sellers as 041DB002-2) is the genuine OEM control and radio receiver board for select LiftMaster and Chamberlain residential garage door openers. This replacement “receiver logic board” is the heart of the opener: it manages motor operation, limit and force control, Security+ rolling code radio reception for remotes and wireless keypads, wall control inputs, and the safety reversing sensor circuit. Replacing a failed logic assembly can resolve symptoms such as remotes not responding, erratic operation, or the opener not running despite good power and intact safety sensors.

Compatibility is model- and frequency-specific, so match 41DB002-2 to your exact opener by checking the opener’s parts label and the color of the Learn button under the light lens (LiftMaster uses Learn button color to indicate radio frequency families). When correctly matched, this board works with the corresponding Security+ remotes/keypads and supports standard monitored photo-eyes. Installation requires disconnecting power, transferring connectors and terminal wires (wall control, safety sensors, motor, antenna), securing the board, then restoring power. Afterward, reprogram remotes/keypads via the Learn button and reset travel/force per the opener manual, finishing with a UL 325 safety reversal test. For verified model coverage and programming steps, consult LiftMaster’s parts charts and your opener’s service manual.
