The most common problem whenr garage door sensors are not working properly is that they are dirty or that they are out of alignment. The best way to ensure that they are clean is by putting Isopropyl alcohol on a cotton swab and then wiping the sensor glass clean. If you are still experiencing problems you can align the sensors yourself. It is of vital importance that a garage door functions properly as a faulty door can endanger the life of your family and pets and put your security at risk.
Things You’ll Need
- A tape measure
- String that is long enough to tie to each sensor
- It is vital that you turn off the electric breaker or disconnect it from the power supply. This is done to prevent electrical shock whilst working on the sensors.
- Note where the garage door sensors can be found. They are located approximately 4 to 6 inches, on each side, from the bottom of the garage door rail. You need to loosen the screws on each of the sensors. This as to allow the small amount of force needed to move up or down.
- The maximum height allowed for the sensors is six inches of the ground. You must adjust each garage door sensor to no more than this height off the ground.
- Next you must tie the string to each of the garage door sensors that you have just adjusted.
- Remember that the string must be above and only touch the level very gently. If you find that the string is not level you will have to do adjust the garage door sensors so that they are level to the string. Note also that each garage door sensor must not exceed a height of
6 inches from the ground.
- Now you need to tighten the screws on each of the sensors. Then check that the string after tightening the screws on the garage door sensors is still level…
- Now you can untie the string from each of the garage door sensors.
- You are now able to turn on the electrical breaker or reconnect your power supply.
- To test the alignment you can roll a soccer balll between the beams. This is a test to be sure that the garage door sensors are functioning as they should.
- Your garage door sensors might still not be working as result of fingerprints left on the sensors. Clean the sensors again with isopropyl alcohol on a cotton swab. You will have to replace the sensors if they remain faulty…
