If you’re wondering what color the lights should be, the answer may be a bit confusing because there isn’t a uniform color for the lights on these sensors. Most manufacturers will have different colors and layouts for their sensors. Some might not even have lights at all. In this article, we dive into what the lights on the sensor mean and also test if they work. Read on to find out more.

What are Garage Door Sensors?

There’s a federal law out there that requires all garage doors made after 1993 to have an automatic reverse function that turns on when there’s an obstruction. In simpler terms, these doors have to be able to detect if there’s something in the way of the door while closing, and if it senses an obstruction, the door will reverse and return to the open position. Your garage door may keep going back up because it detects something in its path. 

What do the Lights Mean?

Most people think that these sensors have a universal color that all brands follow, but that isn’t the case. This can lead to a lot of confusion, but the way to get past that is to not focus on the color but to focus on whether the lights are blinking or not. While there is a lot of variation when it comes to the light’s color and their meaning, there’s a general rule of thumb when it comes to them blinking. If you notice one of the lights blinking, that means that the sensors aren’t aligned properly which could lead to the sensor not working. This is easily fixed though, all you need to do is realign the two sensors to get the blinking to stop. If the LED lights on the sensor stop blinking, now you can check if the sensors actually work.

How to Check Garage Door Sensors

A garage door repair tip is to always inspect and make repairs before further damage occurs. To check the sensors properly, all you’re going to need is a cardboard box, a tape measure, a soft cloth, and the remote control of your garage door.

Start by measuring the height of your sensors, once you have that, choose a cardboard box taller than the height of the sensors. You can stack a couple of boxes on top of each other to get the right height. Put the boxes in between the sensors and close the garage door. If the door stops closing and reopens without crushing the boxes, then your sensors are working fine. But if the box gets crushed, there are a couple of things you need to check.

First, check if the LED light is blinking. If it’s still blinking, you can realign them some more by tightening the screw on the bracket where the sensor is or even bending the bracket a little to realign it can do the trick. However, if the light isn’t blinking and the boxes were still crushed, you could be dealing with a dirty lens.

If that’s the case, all you need to do is get the soft cloth and wipe the sensors clean. Once that’s done, the door should automatically stop if it detected an obstruction. If it still doesn’t work after cleaning and realigning, it might be time to check all the wires because if the wires are damaged, it might be time for you to get a new sensor altogether.

Conclusion

If you are wondering what color are the garage door sensors supposed to be, you now know it’s actually whether or not they’re blinking. Of course, it would also help to read the manual of the sensors if you still have it on hand as that would contain information specific to the exact model you have. But if you don’t have that, these general rules with garage door sensors should be enough to test and troubleshoot problems with the sensor. When it comes to various garage door repair tricks, keep in mind the importance of maintaining it, which includes the sensors.
