What is a light beam?

Has your garage door ever started to go down and immediately gone back up? Will it not close? Your first option is to check your light beams! They are the small black boxes on either side of your garage door inside your garage.The job of the light beam is to stop your garage door from closing with an object under it. Most home owners get light beams to protect pets and children. There is an invisible light beam that reaches between the two black boxes. If the boxes lights are on, but blinking you know that they are not aligned properly. You can manually wiggle the box to realign it with the one across from it. Once both beams lights are on and steady you can try your door again and it should close properly. If it doesn't give us a call and we will come check it out for you!
