It is extremely important to understand that garage door sensors play a crucial role in increasing functionality. Their purpose is to stop a garage door from closing if there is an obstacle underneath. Sensors reduce the risk of injury and damage to your car and other objects found on the way to the garage door.

Main Problems With Garage Door Sensors

The main indicator that something has happened to the sensor is that it is not working properly. If the door does not open or close or does not do so every time you need it. This can lead to serious injuries in the future, which is why this problem is similar to an iceberg – the consequences of a sensor failure are more serious than they appear at first sight.

The most common indicators are that the garage door sensor is not all right:

• Sensor path
• Sensor power
• Sensor lenses
• Sensory moisture
• Sensor alignment
• Sensor age

One of the easiest ways to check the sensor is to use several cardboard boxes. You should take several cardboard boxes and place them under the open garage door to check if the garage door sensors are working correctly. Since the sensors are about 6 inches from the ground, take the boxes higher. Try closing the garage door.

If the sensors are functioning properly, the boxes should interrupt the light beam between them, and the door remains open. Either the doors will start closing, but then they will open without touching the boxes. If the sensors are not working properly, the door will close completely or open again after closing, damaging the boxes.

Fixing Problems With Garage Door Sensors

Depending on the problem, the repair of the sensor will be different in nature, in some cases, you will need professional help.

Interference in the Sensor Path

This is one of the easiest options to fix very quickly, just remove the obstacle from the sensor beam. Also, wash the floor well to remove all sorts of small objects that the Sensor perceives as an obstacle.

Incorrect Sensor Power

This can happen due to a power outage that caused a malfunction or poor wiring, and sometimes the sun creates problems with the sensors. If the sun rays fall at a certain angle on one of the sensors, they will interfere with the light beam and cause problems. 

If it is a matter of wiring, then it is worth checking all the wiring that powers the sensor, but it is worth doing it with special equipment so as not to hurt yourself. If you do not have the skills of an electrician, it is worthwhile to contact a professional.

Dirty Sensor Lenses

If you live in a busy street and the garage door is often open, dust and dirt will accumulate on the sensor lenses daily. Since they are the size of a pea, they easily get dirty over time and stop sending the signal needed to close the door. Use a soft microfiber cloth to remove all dirt from the lenses, but be extremely careful not to scratch them. Make sure that everything is thoroughly cleaned, the sensor should work if this is the problem.

Sensor Moisture

This is one of the most common reasons. This is because many of the sensors are exposed to rain. Under these conditions, it is best to wait. It would help if you waited until the moisture has dried up and then clean the sensor well with soft microfiber.

Sensor Alignment

Sensors with incorrect sensor positioning are not uncommon. Check that the alignment is correct. If there is room for adjustment, make sure the sensors are facing each other.

Sensor Age

If you use the sensor for a long time, the problem will be the wear and tear on the sensor itself. Sometimes the wear is so severe that it is beyond repair. At such moments, you can always think about completely replacing the sensors. 

Conclusion

Even if you do not have any sensor problems, you should check the sensor periodically as a precaution. However, a failure of the garage door sensors can have a significant impact on their operation, your safety, and the integrity of your vehicle.

However, while the remote control of your garage door makes your life comfortable, there are also new problems that may arise.

Reasons To Change The Code On Garage Doors

1. If you moved into a new house, where there are garage doors with a remote control to avoid theft in the future because you never know who had access;
2. If you suspect that your code may have been compromised or stolen;
3. For security reasons, it is recommended that you change the code every six months.

Types Of Garage Door Openers

There are two main types of garage door openers.

If you can’t find the one you have, I would recommend that you consult with the installer or check the back of your garage door opener. There should be instructions there.

How To Change The Code In Garage Doors

Resetting the code for a garage door opener depends on which option you have. While resetting a newer garage door opener takes just a few seconds, resetting an older version takes a little longer.

Change The Code On The Garage Door Without A Wall Keyboard

1. Remove the remote control cover: after removing the cover, you will notice that there are several switches underneath. You use these switches to change the code.
2. Compare the position of the switches: after examining the switches in detail, compare their position with the code for opening existing garage doors. This will show you how to position the switches for the code.
3. Reset the switches to a new code.
4. Get access to the garage door motor attached to the garage roof.
   Then remove the motor cover in the same way that you remove the remote control cover. When you open the lid, you will see a series of switches similar to those you saw on the remote control.
5. Resetting the switches: Be very careful to move the switches in the same way you moved them on your remote control. The success (or failure) of the whole process depends on this step. So be very careful and cautious.
6. Check if the remote controls are opening the garage door. If the door does not open, check again the position of the switches to make sure that they match.

Change The Code On The Garage Door With A Wall Keyboard

1. Access to the garage door engine block located on the roof of your garage. You will be able to find the motor on one of the two sides of the garage doorway.
2. There must be a “Reset” button on the side of the motor. Press and hold the button on the side of the motor until the light goes out nearby. This will indicate that your door memory is lost and the old code has been erased.
3. Press the “Reset” button on the engine control panel again. Keep the button pressed until the light comes back to life.
4. Then go to the wall keyboard and enter the code you have chosen. When you enter it, you will notice that the indicator light will start blinking. This is an indication that the engine has accepted your new code.
5. Then press and hold the button on the engine until the flashing light starts to blink. Keep pressing the button until the light goes out again.
6. Press and hold the button on the remote control. You will notice that after a few seconds of waiting the light on the motor will start blinking again. This means that you have successfully reprogrammed the new code on the remote control.
7. If you have other remote controllers, you should reprogram them too.
