How Do Garage Door Safety Sensors Work?
Garage door safety sensors emit an invisible infrared beam across the garage door opening. If that beam is interrupted while the door is closing, the door will automatically stop and reverse. The sensors are usually located just a few inches off of the ground on either side of the garage door opening.
It’s important to keep in mind that these beams are very sensitive, so even if something as small as a leaf or a piece of debris interrupts the beam, the door will stop. If you find that your garage door isn’t closing all the way, or if it’s stopping and reversing for no apparent reason, there’s a good chance that one of the safety sensors is malfunctioning.
Common Causes of Malfunctioning Garage Door Safety Sensors
If your garage door safety sensors are no longer working properly, here are some of the most likely causes:
Dirt and Debris
One of the most common problems is simply that the sensors have become dirty or covered in debris, which can interfere with the sensor’s ability to emit a consistent beam.
Improper Installation
Another common issue is that the sensors have become misaligned, which can also interfere with the beam.
Connection and Power Issues
It’s also possible for the sensors to become disconnected, or for there to be a problem with the power supply. If you find that one of your sensors is no longer working, it’s important to check all of the connections and wires to make sure they’re secure. Sometimes these wires can be disconnected when the casing is nudged out of place. If the connections seem to be secure, then you may have a problem with the power supply, or the batteries in the sensors may need to be replaced.
How To Evaluate Your Sensor’s System
If your garage door isn’t functioning properly, there’s a good chance that one of the safety sensors is to blame. However, before you call a professional to take a look, there are a few things you can check yourself.
- First, take a look at the sensors and see if they appear to be obstructed in any way. If they are, remove the obstruction and see if that solves the problem.
- Next, check to see if the sensors are properly aligned. They should be pointing directly at each other with nothing in between them. Often there is a red or green light that indicates whether or not the sensors are aligned, so you can easily check this yourself.
- If the sensors appear to be clear and properly aligned, then the next step is to check the connections and wiring. Make sure that all of the wires are securely connected and that there is no damage to any of the wires. If everything looks to be in order, then you may need to replace the batteries in the sensors.
If you’ve checked all of these things and your garage door still isn’t working properly, then it’s time to call a professional. A qualified technician will be able to diagnose the problem and get your door back up and running.
