How to Replace the Logic Board on a Garage Door Opener
The logic board inside a garage door opener is the brains of the garage door opener. It contains the radio frequency (RF) receiver for the remotes and other control components. If the remote controls don't work or the garage door doesn't open and close properly, the logic board might have failed. Follow the steps in this repair guide to replace it using a manufacturer-approved replacement part.

Warning: Undertaking repairs to appliances can be hazardous. Use the proper tools and safety equipment noted in the guide and follow all instructions. Do not proceed until you are confident that you understand all of the steps and are capable of completing the repair. Some repairs should only be performed by a qualified technician.
Step 1: Disconnect power
Unplug the garage door opener. Open the lens cover and remove the light bulb. If your model has a back-up battery, disconnect it.
Step 2: Disconnect the control wires
Release the light’s lens cover from the bottom brackets and set it aside.
Disconnect the wires from the control panel—the method for releasing the wires varies by model.
Step 3: Release the control panel
Remove the 4 mounting screws from the control panel. Release the control panel from the motor unit.
Step 4: Disconnect the logic board
Tip the control panel forward. Take a digital picture of how the wires connect or note the location of wires, so you know how to attach the new board. Detach the wires from the logic board.
Remove the mounting screws from the logic board. Release the locking tabs and pull the logic board out.
Step 5: Install the new logic board
Position the new logic board on the control panel and snap it into the locking tabs. Line up the mounting screw holes, insert the mounting screws and tighten the screws firmly.
Step 6: Reinstall the control panel
Connect the wires on the new logic board. Position the control panel on the motor unit, insert the mounting screws, and tighten firmly.
Step 7: Reinstall the light lens cover
Engage the hooks of the lens cover in the brackets at the bottom of the motor unit. Push the top of the lens cover so the locking tabs on the motor unit snap into place.
Step 8: Test the logic board
Plug the motor unit in. Reinstall the back-up battery, if your model has one. Test the garage door opener to make sure the new logic board works.
