Garage Door Beam Sensor Alignment

To adjust the sensor loosen the wing nut with your wrench and set t it to the exact height that the other sensor is at.

Garage door beam sensor alignment.

The working of these sensors is quite simple. Proper height for a garage door sensor is 4 to 6 inches 10 2 to 15 2 cm. One of the sensors directs a beam toward the other. Give your garage door opener a try.

The infrared beam from the garage door opener sensors isn t able to be seen by human eyes. Tie a string long enough to span the width of the garage door around the bracket on one side so that the string will line up with the sensor lens.
