Your Guide To Troubleshooting Garage Door Sensors 

This guide to troubleshooting garage door sensors will show you four different ways to address a problem your garage door sensors might be facing. See if any of these troubleshooting tips make a difference for your garage door. 

1. Adjust The Sensor Alignment

The first step in troubleshooting garage door sensors is to ensure that the garage door sensors are aligned. All you need to do is look at the color of the sensor lights. One is red, while the other is green. If the red light blinks, the sensors are unaligned. To realign them, move the one with blinking red lights slightly and see if it stops blinking. If necessary, adjust the green light one too. If the lights stop blinking, your garage door sensors should be in good shape again. 

2. Clean The Photo-Eyes

If your garage door is still having issues despite realigning the sensors, it might be due to excessive dust or moisture blocking the photo-eyes. Gently clean them both with a dry cloth. In fact, staying on top of cleaning the photo-eyes of your garage door sensors is a great way to maintain this part of your garage door. 

3. Inspect The Wiring 

The next part of troubleshooting garage door sensors involves a wiring inspection. Just see if the sensors’ wiring path to the power source shows any fraying, tears, twists, or snaps. If the wires are twisted, carefully untangle them. If they are broken, have a professional take care of them for you. 

4. Check The Power Supply

Sometimes, troubleshooting garage door sensors comes down to a hard reset. In other words, the problem might be with the power supply. First, disconnect and turn off your garage door opener. Then, find the switch on your circuit board and flip it. Reconnect and turn your garage door back on before seeing if that makes a difference. 

5. Check For Sunlight Interference

Finally, sunlight exposure might be another possible source of interference with your garage door sensors. Depending on the positioning of your garage door sensors, they might be on the receiving end of sunlight at certain times of the day. This exposure keeps the beams from the photo-eyes from making contact with each other. If this seems to be the problem, put pieces of cardboard at the sides of the sensors to block any sunlight, allowing the photo-eyes to connect and ensuring your garage door works properly.
