Fortunately, replacing your Chamberlin garage door opener logic board is not difficult, and you can do it yourself by following a few simple steps.
• Remove the opener lens and bulb by pressing the release tabs. Remove the access door and wires from the terminal screws.
• Remove the old logic board by unscrewing the screws found under the top edge of panel and the screws fastening the board to the panel. Unplug the wire harnesses and discard old board.
• Plug wire harnesses into new logic board in the right position and fasten the assembly back to the chassis. Insert the door and safety sensor wires through the slot on top of the panel and fasten the new logic board to the panel.
• Connect door control and safety sensor wires to the appropriate terminals. Replace access door, cover and opener lens.
