Garage Door Sensors 101: 5 Signs That They Need Repairs

by | Aug 16, 2022 | Garage Door Repair Fort Lauderdale

Most homeowners don’t think about their garage door sensors very often, but these devices play an essential role in the safe operation of your garage door.

In this blog post, we’ll discuss what garage door sensors are, how they work, and what signs indicate they may need to be repaired.

How Do Garage Door Sensors Work?

Garage door sensors are devices mounted on your garage door’s sides. They are typically about the size of a smoke detector and have a small light on the front. These sensors are connected to your garage door opener via wires.

The purpose of garage door sensors is to prevent the door from closing if there is something in the way. The sensors work by sending out an infrared beam. If the beam is interrupted, it will trigger the sensor, and the door will not close.

How Can You Diagnose If Your Garage Door Sensors Are Not Working?

There are a few signs that your garage door sensors may need to be repaired. If you notice any of the following, it’s a good idea to call a garage door repair technician.

1. The Wires Are Damaged

If the wires that connect the sensors to the garage door opener are damaged, the sensors will not work properly. This is usually caused by rodents chewing on the wires. If you see any damage to the cables, it’s best to call a professional to repair them.

2. There Are Electrical Issues

If the sensors are not receiving power, they will not be able to function properly. This can be due to several different electrical issues, such as a loose connection or a blown fuse. Check the electrical connections to the sensors and make sure they are secure. You may also want to check the fuse box to see if a fuse has blown.

3. The Door Won’t Close Properly

Garage door sensors may be the cause of the doors not closing correctly. Try closing the door manually to see if it will close all the way. If the door does not close properly, it is likely that the sensors are not aligned properly.

4. The Photo Sensor Lights Are Malfunctioning

The photo sensor lights should turn on when the door is closed and turn off when the door is open. If the lights are not functioning correctly, it could be a sign that the sensors are not working.

5. The Sensors Are Dirty

Dirty sensors can also cause problems. The sensors need to be able to see the infrared beam in order to function properly. If the sensors are dirty, they may not be able to see the beam properly. Clean the sensors with a soft cloth to remove any dirt or debris.

Final Thoughts

Knowing the signs that your garage door sensors may need repairs is essential. By understanding how the sensors work and what can cause them to malfunction, you can be sure to take care of the problem before it becomes a more significant issue. Be sure to check the wires, electrical connections, and photo sensor lights regularly to ensure that your garage door sensors are in good working condition.

Steven showed up on time, did troubleshooting, then provided an estimate at no cost.
We scheduled a time for him to come back to replace with a chamberlain. He again showed up on time, and completed the work well ahead. He also provided preventive maintenance.

I have an old heavy door from the 50’s with a pretty unique arm & spring system which broke. Terrie was able to fabricate a new arm and reattach and the door has never worked smoother or quieter. Terrie was prompt, fair priced, came up with an ingenious…
