Product Description
If your LiftMaster Chamberlain 2500 DC Belt Drive garage door system isn’t operating correctly, you may not need to replace the entire system or call a professional. Many times, the reason for the system’s failing is due to a faulty circuit board. The circuit board is the system’s brain, and an unresponsive keypad, remote control or faulty sensor may all be due to the circuit board. If you have a faulty 2500 system, you may only need to replace your LiftMaster Logic Board 41A5507. Repair the system yourself by following a few simple steps.

Press the plastic release tabs to remove the opener lens and bulb. Remove the access door and sensor wires from the terminal screws.
Unscrew top edge panel screws and the screws fastening the old board to the panel. Remove the wire harness.
In the correct position, plug wire harness into the new 41A5507B logic board and fasten the assembly back to the chassis. Thread the door and safety sensor wires through the slot on top of panel and fasten the new logic board to the panel.
Connect door control and safety sensor wires to the appropriate terminals. Replace access door and opener lens.

For further details on how to safely replace your logic board, the Chamberlain 41A5507-B manual can be found in our comprehensive list of Product Manuals, and you can ensure your system is compatible with the 41A5507 logic board by viewing our Chamberlain LiftMaster Circuit Board Compatibility Chart.

Many times, an inoperable circuit board is caused by powers surges or lightning. When replacing your circuit board, we recommend the 990LM Garage Door Opener Surge Protector to protect your new logic board.
