If the door works but you have trouble opening or closing it, worn springs may be the culprit. If the springs look worn, you should have a professional look at them. Working on springs yourself can be dangerous since they are under high tension. The same goes for worn cables, which attach the springs to the bottom of the door and provide the proper leverage for lifting. If they are beginning to fray, this is pretty serious. Loose brackets can be another reason you have trouble opening your garage door. The brackets hold the cable to the door and thus are under a lot of pressure. You should almost never mess with these yourself for the reasons stated above.
