Whether you're facing this issue now or preparing for future obstacles, a deep knowledge of sensor alignment can save you time and money.

Understanding Garage Door Sensors

‍

One of the most essential roles of a garage door sensor is to ensure that the garage door system stays safe and functions properly. According to insights from garage door repair vancouver experts, these devices are programmed to detect any obstacles in the door’s path, preventing accidents and damage. However, when they become misaligned or malfunction, the garage door may fail to close properly, leaving your home vulnerable. Seeking professional assistance can help diagnose and fix the issue, ensuring your garage door operates smoothly and securely.

Common Causes and Initial Assessment

‍

Sensor misalignment is often caused by vehicles, lawn equipment, or enthusiastic pets bumping into them.  In busy families, small impacts are so frequent that the sensors might get out of alignment without even realizing it.  

‍

Other factors are the temperature swings, wind, and humidity through which a sensor can easily be displaced. Before troubleshooting or replacing parts, it is important to confirm that misalignment is the issue. 

Most garage door systems include LEDs mounted on the sensors,  a continuously glowing light means all is well, while when it is flashing, then misalignment or other issues are present. This straightforward test can be useful during diagnosis and save time.

The DIY Repair Process

‍

Fixing sensor misalignment is a simple task that most homeowners can do. You should first begin by checking the brackets that support the sensors in place. The brackets will start getting loose over time, making the sensors go out of the needed spot. 

‍

However, in some cases, doing a slight manual touch and then screwing the mounting screws can do the job. When adjusting the sensors to be perfectly aligned, in order for both the sensors to be of the same height, a level should be used. 

‍

A light beam must be perfectly horizontal; any deviation can cause system malfunctions. To check sensor alignment, a useful method is to stretch a thread between them to guide the laser beam.

Troubleshooting Common Complications

‍

It seems that a misalignment problem might be quite serious. Sometimes, a small amount of dirt or cobwebs on the sensor lenses can make the sensor look improperly aligned.

‍

Dirt buildup is the main cause of this issue. Additionally, you should examine the cables that link the sensors and the garage door opener to make sure that they have no damage or are not short. If your location is one with extreme weather conditions, it is better to install protective covers over the sensors. 

‍

Even though these extra accessories are not required for the majority of installations, they are easy to use and can prevent misalignments caused by weather and prolong the life of your sensors.

‍

Advanced Considerations

If basic realignment does not resolve the issue, the sensors themselves may be faulty. Garage door sensors typically last 10-15 years, but in case there is a situation like power surges or physical damage, this time can be shortened. These sensors should be replaced with a model recommended by the door's manufacturer that will be the most appropriate one.

‍

In Closing

‍

A misaligned garage door sensor can escalate from an inconvenience to a safety hazard, so ensure proper alignment. While it is well understood that qualified help is always available, the know-how of the sensor's diagnostic and correction of misalignment gives homeowners the courage to solve these problems themselves with certainty. 

‍

Keep in mind that regular maintenance and the fast correction of the imbalances are the two things that help you get rid of the bigger issues and, at the same time, the repair process of your roller door will look like a part of your daily routine instead of being a source of discomfort. 

‍

If you are unsure, consult a professional rather than attempting repairs. The garage door is a big unit in your home that works properly and allows you to live comfortably and safely.
