If you have an automatic garage door, there are two sensors at the bottom. They send out an invisible beam of light to act as a detection barrier that stops the garage door from closing if it's obstructed at all. These sensors may experience the following complications, but you can deal with them correctly by performing the right repair steps.

Dirty Surfaces

A common but simple problem that can affect your garage door eye sensors is the accumulation of dirt and debris. The garage typically a dusty place so it's common for your sensors to get dirty and then not function properly. 

You'll want to get some cleaning solution and a rag to wipe the surface of these eye sensors. A cleaning solution specifically designed for garage door parts is ideal in getting results quickly.

Damaged Frames

In order for these sensors to send the proper signals to work, the frames that they're supported by need to be in great shape. If they're not and hang down even by just a little, it will be difficult for the receiver to receive a signal from the transmitter.

If the frames aren't that thick, you may be able to manipulate them back into the correct position without any specialized tools. Just make sure you don't grab onto the sensor when adjusting the mounts. Rather, place your hands firmly on the mount and push up or down depending on how the sensor frames are misaligned.

Wet Sensors

If you're in a humid area or it just rained, then your sensors can get wet and then malfunction. Before finding a replacement, try drying the sensors to see if they're still operational. You'll just need a rag for this step.

If the sensors still don't work after you've dried their surfaces thoroughly, then you may have faulty eye sensors. Either you can have a professional come out and verify this or you can order a replacement set. The former option is probably a better idea if you have an expensive set of garage door eye sensors and want to salvage them.

An important safety feature of automatic garage doors is the eye sensor on both sides. They need to be in great shape to work properly, which involves sending signals and stopping the garage door when these signals are interrupted. If you monitor these sensors carefully and step in when they malfunction, you can keep your garage door functioning safely.
