Before the 1990s, garage door related accidents were common as most doors shut blindly and could not detect human presence or obstacles underneath them. Thus, the government mandated the use of safety features, such as the photo eyes to prevent further accidents. Today, all garages have these sensors that stop the doors from closing when an obstacle is detected.

How Do Photo Eye Sensors Work?

The mechanism of photo eyes is rather simple. They are placed six inches above the ground on either side of the garage door and must be installed facing each other. These sensors send out invisible beams that communicate with each other. If the connection is interrupted and the two sensors lose contact, the sensors signal the circuit to either reverse or stop the garage door from closing.

What Are the Common Sensor Problems?

Even though the system is very basic, there are instances when the sensors won’t go off and do its job. Thus, it is important to have your system checked regularly. Here are some common sensor problems:

• Dirt & Dust: Excessive dirt and dust can interfere with the sensors’ signal, preventing good communication. For this reason, you must clean your sensors regularly.
• Wiring System: Worn wires should be checked and replaced immediately to ensure that your system will work properly.
• Receiver Misalignment: Since doors are used most of the time, there are instances when the receiver misaligns with the transmitter. You can easily detect misalignment because the LED lights of the receiver will blink if the signal is lost.
• Sun Blind: If you notice that you have problems with your opener during the day, it is possible that the sun blinds one of your sensors. You can have a sunshade installed by a garage door repair specialist to resolve this problem.
