How to Fix the Garage Door Sensors?

Garage doors are an essential part of our homes, providing security and convenience. But when the sensors that detect whether the door is closed or open malfunction, it can be a real nuisance. Fortunately, fixing broken sensors is not as difficult as it seems, and in many cases can be done without professional help. In this article, we’ll provide step-by-step instructions on how to fix garage door sensors yourself.


The first thing you should do when your garage door sensors are not working properly is to check if the sensors are clean and free of debris. This includes checking for dirt, dust, leaves, and anything else that might be blocking the sensors from functioning properly. If you find any blockage, simply wipe it away with a damp cloth.

Next, check the alignment of your sensors. When they are misaligned, they will not be able to detect whether the door is closed or open. To fix this problem, adjust the sensors until they are lined up correctly with each other.

If your sensors still aren’t working after cleaning and alignment, it’s time to check the wiring of your system. Disconnect the wiring from both sensors and make sure the cables are secure and not damaged. If any of the wires appear to be frayed or otherwise broken, replace them with new ones.

Finally, if all else fails, you may need to replace your sensors entirely. Although this can be a bit costly, it is far more reliable than attempting to repair the existing sensors. Check the user manual of your garage door, and make sure to purchase sensors that are compatible with your system. You can also consult with an experienced garage door replacement Newport News technician if you need any assistance.

By following these steps, you can easily fix your own garage door sensors and save yourself the cost of hiring a professional. With just a bit of knowledge and effort, you can get your garage doors working properly in no time.
