A garage door must be properly maintained in order to keep it working properly. There are small things that you can do to your garage door to keep working at maximum efficiency without having to call a service person. Align The Sensors The sensors on the garage door can throw off the entire opening and closing of the door if they are not in proper alignment. Take a long piece of string and tie one end to the sensor on the left side and then tie the other on the right side.
