If you have issues opening or closing your garage door, chances are you have a problem with your safety sensors. These sensors will usually have an emitter and receiver. Safety beams will usually come in sets and each manufacturer uses different colors. However, most garage doors will have similar colors. So, what color should the lights be on garage door sensors?

how garage door sensors work and the color the lights should be. We’ll also highlight the significance of hiring a professional to fix the issue.

How Do They Work

Garage door sensors work using an infrared beam of light. The light is emitted from one side of the garage door to a receiving unit on the other side of the door. If the path between the sensors is unbroken, the door will open and close normally. However, if the sensor detects an obstruction that prevents the door from closing, say your dog is running under the door as it’s closing, that breaks the path between the sensors and a signal is sent to the opener. This activates the automatic reversing mechanism and reverses the door to prevent injury.

These sensors are little black boxes found on either side of the bottom of the garage door. Each sensor will usually have a light. One will have a green light, used to show that the units are powered up, and the other will have a red light to show that there’s no obstruction between the sensors and that they’re ‘seeing’ each other.

If the sensors are thrown out of alignment, then the red light will blink. To fix this, all you need to do is simply re-align them by moving one of them until the red light stays lit. Sensors are usually attached to the garage wall by metal supports, but they’re easy to reposition or bend if necessary. Another possible problem could be the sun. If the sun shines on the sensors, it may hit it in such a way as to block the light. A simple fix would be to block out the sun by fixing a piece of cardboard in

front of the sensor.

If the light is still blinking, there may be a problem with the wires connected to the sensors. Be sure to check that the wires have been securely attached. It’s also important to check that one of the wires hasn’t been cut. It’s important to note that you can find the error code on the motor unit by counting the number of times the red-light blinks. Simply check the user’s manual to troubleshoot the problem and see if you can fix it on your own.
