If you suspect this is.
How do i fix my garage door sensors from the sun.
In this case you will set up the level aligned with one sensor then adjust the opposite sensor until the beam of your laser level is hitting the sensor.
Move the sensors into the garage and out of the sun switch sides the sides of the sensors putting cardboard like a toilet paper tube around the sensor will block much of the sunlight.
If you have a laser level you can use it instead of a string to align your garage door.
If you have a problem with the garage door only at a certain time of day it is possible that the sun is shining into one of the sensors and causing it to break the circuit.
Just moving them back might solve the problem since they ll be blocked by the walls.
But avoid blocking the actual sensor part with it.
If this problem keeps reoccurring and the door won t shut simply press and hold the wall button continually until the door is fully closed.
Proper height for a garage door sensor is 4 to 6 inches 10 2 to 15 2 cm.
If it isn t it could get in the way of the electronic beam and prevent the garage door from closing because the cardboard tube is breaking the beam.
