How Do Garage Door Safety Sensors Work?

Safety sensors are an important feature of all residential automatic garage doors. In fact, federal law requires them on all garage door openers that are manufactured after 1993. For added safety, any automatic garage door opener that doesn’t have a safety reverse mechanism properly connected and installed in it won’t even travel in the down position.


This simple safety feature was designed to protect people from getting trapped or injured by closing garage doors. Garage door safety sensors work by automatically reversing the course of the garage door when it comes in contact with an object or person while it is descending.


The safety of your loved ones is important, which is why it’s crucial to make sure that your garage door safety sensors are working properly. If they aren’t, here are a few things that you can check for a possible quick fix to your problem.

How Do I know If My Garage Door Sensor Isn’t Working?

Garage door sensors also have built in functions to let you know there’s a problem. Dirty sensors, misalignments, or damaged components can cause sensors to malfunction. A sensor can be thrown out of alignment if something bumps into it. Or, an impact can damage the connection wires, while vibrations from the garage door or direct sunlight may affect it. As a result, the door may work erratically.


If a sensor malfunctions, the door might suddenly stop and reverse for no reason, open but not close, or a light may flash on the sensor, from an overhead component, or the wall panel.

Can Garage Door Sensors Be Repaired?

When dirt is coating the sensor eye, usually all you need is a soft, clean cloth. Misalignments may be corrected by bending the sensors back into position or tightening the screws of the bracket holding the unit in place. If there seems to be no easy fix, a garage door professional can troubleshoot the problem and determine the best course of action to fix it.



If you decide to try to fix the sensor on your own, make sure the area is shaded and disconnect the power to the sensors. Call a technician if you suspect a wiring problem. You won’t be able to access wiring inside the sensor casing; only a specialist knows how to properly address this problem and replacement of the sensor system may be required.
