A blinking light on the garage door sensor isn’t really cause for alarm, but it does let the homeowner know that something’s not working quite right. With any garage door that isn’t raised and lowered manually, having good automation is part of the value. That’s how the door knows to raise and lower when a button is pressed or an object is detected underneath it. A lot of times these door sensors are a part of a bigger home automation and security system, and even a really good security system is occasionally going to experience trouble.

Blinking green sensors generally mean that the door has detected a fault or a safety issue, so it’s a way of letting a homeowner know there’s a problem. Otherwise, the light is generally on steady green, instead. Often when there’s a blinking green light, the door also won’t operate with the remote. It can still be raised and lowered by hand, but that ruins the point of having a powered garage door and a home automation system — so it’s important to figure out why the light is blinking and get it fixed so the door works right again. There are several ways to address the problem.

Isn’t Green a Good Thing?

Green is usually a good thing, but the blinking green light on a garage door sensor needs some troubleshooting. One of the first things a homeowner should do is check to see if there’s something in the path of the garage door’s safe operation. The sensors use infrared light to detect things, and if the beam between the sensors is being broken by an object, the light will blink and the door won’t work.

Moving the object or clearing away any debris or other issues can restore the lights to solid green and get the door working again.

If that doesn’t do the trick, one of the sensors may have detected a fault in the system. That can sometimes be cleared by disconnecting and reconnecting the power, and then restarting the system. Garage doors sometimes experience glitches, so it’s important to be patient and work through troubleshooting options in order to find the cause of the issue. A faulty sensor could be to blame, too, in which case the sensor itself will need to be replaced in order to restore proper garage door operation.

Make Sure to Troubleshoot Correctly

Don’t automatically jump to the conclusion that the sensor is bad, or that the security system or home automation company that installed the sensors needs to be contacted. By taking some time and looking through the possible simple explanations for the issue, most homeowners can solve most blinking green light problems with their garage door sensors. Only after all of the main troubleshooting options have been tried should the company be called to come take a look and fix the problem.

The Value of a Security System From the Right Company

There’s a lot of value in having a good security system, home automation system, and power garage door. It can provide a higher level of safety and security for a homeowner, and can also offer a lot of peace of mind when it comes to entering and leaving a home. But while a homeowner is shopping for that system they want to consider more than their garage door, such as a company that offers:

  • 24/7 monitoring
  • ease of installation
  • strong customer service
  • fast response times
  • high quality equipment

By working with that kind of company, a homeowner not only has peace of mind but is able to get things fixed faster and more efficiently, too.
