The garage door will automatically go in reverse. If these can t see each other when the door is almost shut it will send a signal to the garage door motor to open back up. If the door seems okay there may be a problem with the trolley or the opener itself. If the door reverses and the lights blink 10 times there s still a problem with the sensors or something tripped them on the way down.
