The garage door sensors keep everyone in your home safe and sound. As a homeowner, you should have sound knowledge regarding automatic garage door sensors. You need to understand how they run to ensure smooth working. Aligning the garage sensors requires some practice. If you can follow a detailed plan, it can streamline the entire process, keeping your family and car safe.

How garage door sensors work:

Garage door sensors sense when an object crosses the path. If the sensor detects something like a person, a car toy, or even a pet as the door closes, the system will automatically reopen the door. Garage sensors use the concept of two photo-eyes. One of the photo-eyes receives the information, while the other transmits it. The sensors are designed to emit infrared lines across the horizontal opening of the garage, which is just inches above the ground.

Both sensors work together and must work properly to avoid bodily accidents and car damage.

How do we understand when garage door sensors are not in proper alignment?

• Signals of malfunctioning will appear when the sensors stop working. You will witness unusual ways of opening and closing the doors. Also, you will be required to exit from the vehicle for closing and opening the garage. Check out for signals and other indicators of the mechanic’s garage door workings.
• The garage door will close despite obstructions. Early detection can help you prevent accidents. You will see the door is closing by overlapping the sensor line. 
• It is essential that the infrared sensor has a clear path for sending messages. Uncleaned lenses may allow sensors to work thoroughly, but they will appear as though they are not correctly aligned.
• Check the flashing light color while pressing the garage remote button. A green light indicates the sensor is in proper working condition. Again, a red light indicates immediate replacement. 
• Damaged wires can cause misalignment, which, if not addressed in time, can lead to functional problems with the garage doors.
• The most common sign of garage door sensor dysfunction is when the door remains open and won’t close automatically. The door will sense objects incorrectly when the sensors are not properly working.

How do you align the garage door sensors?

If you want residential garage door sensors to work correctly, ensure the sensor can pass on information to the other sensor. The information-sending sensor will flash a green light, while the opposite sensor will receive the information and confirm it by flashing a yellow light. Apart from this, it directly indicates an immediate sensor adjustment if anything else appears. Follow the step-by-step process given below for aligning them:

• Switch off the sensor by disconnecting the supply of power. 
• The screws holding the sense should be loosened a bit. 
• Slide the sensor down. 
• Put a string between both sensors. 
• Check out the level of the string lays
• Properly tightening the screws.
