This should only be done by a garage technician because springs are dangerous. The balance of the garage door is important for the operation of the door and the operator/ motor. If the springs are not balanced & tightened properly it can cause extra work on the motor, wear out the springs, cause cables to break, and even damage the sections.
Photo eyes should be checked to make sure they are cleaned off from debris, lined up across from each other on the track, and working properly if something crosses the beam to stop the door. By rolling a ball or placing an object under the door while it is closing you can make sure the safety features are working. This should stop the door from coming down and reverse it, sending it back up. If this does not work properly, the photo eyes need to be re-aligned, and door should not be used until this is fixed.
