A malfunctioning garage door opener system is not only inconvenient, it can also be dangerous for you and your family. If your remote controls, keypad or other programmable system features are not working correctly, it could be due to a faulty circuit board. Fortunately, replacing your circuit board is an inexpensive and easy solution. In most cases, installing your circuit board can be accomplished without the help of a professional. At North Shore Commercial Door, we carry an extensive selection of circuit boards for every LiftMaster model. The LiftMaster Chamberlain 41DB002-2 garage door opener circuit board is compatible with LiftMaster 3850 Elite Series Belt Drive systems. To ensure your system is compatible with the 41DB002-2 circuit board, please reference the Chamberlain LiftMaster Circuit Board Compatibility Chart. Replacing your Chamberlin 41DB002-2 is not difficult, and doing it yourself is simple process.
  1. Press release tabs of the opener lens and bulb to remove. Remove the access door and unplug terminal wires.
  2. Unscrew the screws found under the top edge of the panel and the screws fastening the old board to the panel. Unplug the wire harnesses.
  3. Plug wire harnesses into new logic board, ensuring it’s in the right position, and fasten the assembly back to the chassis.
  4. Connect door control and safety sensor wires to the appropriate terminals. Replace the access door and opener lens.
For in-depth directions and diagrams, please see the 41DB002-2 Product Manual. The manual also provides easy-to-follow directions on how to program, adjust and test your new circuit board. In most cases, faulty circuit boards are caused by power surges and lightning strikes. To prevent future damage caused by power surges, we recommend the 990LM Garage Door Opener Surge Protector for long-lasting functionality and optimal performance.
