What Are Photo Eye Sensors on Garage Doors Used For?

Though a garage door can be an extremely useful piece of equipment, it can also be a dangerous one. Without proper safety features like photo eye sensors, your garage door can cause great harm and, in some cases, death. The moment you notice your photo eye sensors starting to fail, don’t hesitate to call the team at Neighborhood Garage Door Repair for fast, thorough repairs.

Why Are Photo Eye Sensors Necessary?

Prior to the 1990’s, garage doors were not required to have many safety features. As a result, both adults and children were becoming entrapped under automatic garage doors, causing great harm and even death. Similarly, cars and other items left or stuck under a garage door when it started to close also sustained significant damage.

In 1993, as a response to these accidents, the government started requiring that all garage doors to have photoelectric, or photo eye, sensors. These sensors allowed for the garage door to stop proceeding down if something was underneath the door. Though simple, these devices have provided safety and peace of mind to a piece of equipment that was once seen as potentially dangerous.

How Do They Work?

While performing a significant job, photo eye sensors function in an extremely basic way. First, they are located on either side of the garage and have an invisible infra-red beam that goes between them. If anything were to interrupt that beam while the garage door was going down, the sensors would stop the door immediately and reverse it.

It is important that the photo eye sensors are installed about six inches above the ground. Having them too far off the ground could cause them to miss a small child or an animal that is under their line of vision, and therefore fail to stop the door. Additionally, if they are not installed in alignment with each other, they will not work properly.

What If They Stop Working?

When your garage door starts to act up, there is a good chance it could be your photo eye sensors. One of the best indicators that it is them, is that one or both of them will have a flashing light indicating their need for attention. Additionally, your sensors may not be working if your garage door will open, but not close or it starts to close and then immediately proceeds back up.

If you suspect there is an issue with your photo eye sensors, try making sure they are shaded, in alignment, and clean. Sunlight, dust, and debris could be affecting the beam from reaching the other sensor. However, if none of these factors improve the function of your door or photo eye sensors, it is time to seek professional garage door assistance.

They sent Doug Fussell out to my house on the day after Christmas! I had only called them three days before! Doug was a premier technician, very thorough and very efficient. I expected him to take two days, since he was replacing two doors and adding openers on each door. He only took the daylight hours of one day! I could not believe how fast he was! In addition, he thoroughly taught me how to use the remote openers. I highly recommend them to anyone!

We just bought a home and this company was so understanding as I had to change the appointment time a few times. Then the tech came out and was so kind and helpful. I could not have asked for a better experience and will suggest them to anyone who needs work done on their garage door!

My garage door broke on a Saturday night as I was getting ready to leave for a holiday party. Kelvin was here within 30 minutes. He reviewed everything with me that was happening with my door. He gave me the estimates of what was immediately needed to be done in order for my door to raise and then what I will need to have done very soon. I could see all the problems he pointed out to me and I decided to have everything done. He completed everything that night. I was very satisfied with Kelvin’s professionalism and the work he did. Thank you again.
