Garage door sensors could seem like a minor component of the automatic garage door system. However, keeping the safety sensors working properly is decisive in order to avoid any accident.


Safety sensors are programmed to stop the shutting and reverse the door when an object, animal, or person is in the door closing way. If the garage door sensor doesn’t detect that something or someone is blocking the way, the door won’t stop, and the person or animal under the door could get damaged.

Safety Sensors Malfunction: What to Do

Now that you understand how important it is to keep your garage door sensors working in the best condition possible, you should learn what to do when a problem occurs.

First of all, safety sensors have to be cleaned. If they seem to have some issues, try to remove all dust or spider webs that could affect their performance. This should be enough to make them work again.

If cleaning doesn’t work, the problem may be in the wiring. In order to operate, the sensors have to be aligned with each other and properly linked to the garage door system. A bad connection, poorly connected wires, or a short in the wire are the most common causes of safety sensor wiring problems.

To repair any wiring problems, you have to identify the exact location of the poor connection. Check that no sensor has moved and that its beam has not been deflected. Once you do that, check the wire connection between the sensors and the opener; remember that the wires have to match their colors.

Don’t forget to periodically check your safety sensors to avoid major garage door repairs.
