Garage door sensors, also known as safety sensors or photoelectric sensors, play a crucial role in the functionality and safety of your garage door. They are designed to prevent the door from closing if there's something in its path. However, like any other device, these sensors may malfunction over time, making it necessary for you to embark on garage door sensor repair to keep your door functioning optimally.
Understanding Garage Door Sensors
Before you can proficiently perform a garage door sensor repair, it's important to understand how these little devices operate.
Function of Garage Door Sensors
Garage door sensors are connected to the automatic garage door opener and are usually situated about six inches above the ground on both sides of the garage door. Each sensor emits a beam of infrared light toward the other sensor. If anything interrupts this beam while the garage door is closing, the door will automatically reverse.
These safety measures are especially important for preventing physical harm to kids, pets, or property that might be in the way when the door is closing.
Common Problems with Garage Door Sensors
Several common problems indicate you may need to perform a garage door sensor repair. These issues include a door that won't close, a door that opens and closes randomly, or a sensor light that's not lit or blinking. Most often, these problems can be attributed to misaligned sensors, a disruption of the sensor beam, or issues with the sensor wiring.
Signs Your Garage Door Sensor Needs Repair
There are several key signs that indicate that your garage door sensor might need repair or adjustment.
Garage Door Not Closing
If your garage door starts to close and then reverses or refuses to close entirely, it's a strong indication that you may need to carry out a garage door sensor repair or realignment.
Blinking Sensor Lights
If the LED light on one or both of the sensors is blinking or turned off, this usually means that the sensors are not aligned properly or that there's something blocking the infrared beam.
Door Behaving Erratically
If your garage door opens and closes randomly, this can be indicative of a faulty sensor. This erratic behavior is usually due to electrical issues or physical damage to the sensor.
Garage Door Remote Not Working
If you notice that your garage door remote is operating inconsistently or not working entirely, this is another sign that your garage door sensor needs repair. The remote might not be the problem; it's more likely the sensors or the opener itself.
Performing Garage Door Sensor Repair
Carrying out a garage door sensor repair can be relatively straightforward, even for those with little DIY experience. Here are the steps you should follow.
Clear Any Obstructions
The first step in repairing your garage door sensor is to ensure there are no obstructions blocking the sensor beams. Look for any vehicles, tools, toys, or debris that could be creating a hurdle for the beam. Even dust or dirt on the sensor lens can cause problems.
Check Sensor Alignment
The next step in your garage door sensor repair is to check the alignment of the sensors. This can be achieved by measuring off from the floor and ensuring both sensors are at the same height and are parallel to each other. If the sensors are out of alignment, their LED lights will be either turned off or blinking.
Adjust The Sensors
If the sensors are misaligned, they can be easily adjusted by loosening the screws holding the sensors in place, adjusting them until they are aligned, and then tightening the screws back up.
Check the Wiring
If the above steps don't solve the problem, you should check the wiring of the sensors. Make sure that the wires are securely fastened to the sensors and the garage door opener. If there are frayed or broken wires, you will need to replace them.
Replace the Sensors
If the steps above do not solve the problem, you may need to replace the sensors. You will need to purchase a new set of sensors and follow the installation instructions provided by the manufacturer.
