Garage Door Opener Won't work?
If the motor unit has power but won't respond to any remote or the wall control, the logic control board could be the problem. Unplug the garage door opener and check the wiring connections on the panel. If the wiring connections are okay, wait a few minutes before plugging the garage door opener back in—disconnecting the power resets the logic board after an electrical disturbance. Then test whether the opener works. If not, it's likely you need to replace the logic board and possibly other components.
