Can Garage Door Sensors Go Bad?

It is so important for you to know when something goes bad with your garage door hardware. That’s why the Neighborhood Garage Door Repair team put together some information so you know how to check for malfunctions. We hope you find all the information you need in this article to check if your garage door sensors have gone bad.

Can Garage Door Sensors Go Bad?

In short, yes. Garage door sensors can go bad for different reasons and it is vital for you to get them fixed right away. They are put in place to prevent a person, animal, or object from being crushed by the garage door. We have put together some steps to help you better assess the issue.

What You Need to Test

If you find that your garage door sensors are acting up, there are a number of places you can start your assessment. You first want to start by finding out what height the door sensors are at and making sure they are clean and free of debris. If there is something near the sensor, then they will block the door from opening or closing. 

You will want to get a few cardboard boxes that are taller than the door sensors. You will then put the boxes directly in the garage doorway, being sure to block the sensors. Make sure these are not boxes that you will want to be using again, just in case the sensors don’t work and crush the boxes.

Ready to Start Testing

You will first want to make sure that your garage door is completely open and the opener is activated. You can then decide whether you want to open it from the remote or the wall, either one will be fine. If the door closes, that means your sensors are not working properly. At this point, you can check the garage door opener’s alignment or simply call a professional. However, if the garage door returns to the open position, then your sensors are working correctly. 

Checking The Garage Door Sensor’s LEDs

Every garage door sensor that is mounted on the garage door has an LED light that is located on the outside. You will want to check the sensors on both sides. If you notice that either of the LEDs have a blinking light, this is an indication that they are out of alignment.

The LEDs need to be properly aligned in order to function correctly. The sensors can be adjusted by tightening the screws that are supporting them. If the blinking continues then you can bend the bracket until it is in the proper position. 

Could It Be Something Else?

A few other things to check for would be assessing for wetness and checking for wire damage. If the sensors are exposed directly to a sprinkler, rain, or pressure washer, they might fail and should be dried off.  If there is wire damage for any reason, we suggest getting a professional to your home immediately.

They sent Doug Fussell out to my house on the day after Christmas! I had only called them three days before! Doug was a premier technician, very thorough and very efficient. I expected him to take two days, since he was replacing two doors and adding openers on each door. He only took the daylight hours of one day! I could not believe how fast he was! In addition, he thoroughly taught me how to use the remote openers. I highly recommend them to anyone!

We just bought a home and this company was so understanding as I had to change the appointment time a few times. Then the tech came out and was so kind and helpful. I could not have asked for a better experience and will suggest them to anyone who needs work done on their garage door!

My garage door broke on a Saturday night as I was getting ready to leave for a holiday party. Kelvin was here within 30 minutes. He reviewed everything with me that was happening with my door. He gave me the estimates of what was immediately needed to be done in order for my door to raise and then what I will need to have done very soon. I could see all the problems he pointed out to me and I decided to have everything done. He completed everything that night. I was very satisfied with Kelvin’s professionalism and the work he did. Thank you again.
