The receiving sensor should mounted on the side of the garage door opening that receives the least amount of direct sunlight.

How a garage door sensor works.

Sun shields are an inexpensive solution.
Garage door fix to allow it to close when the sun is hitting the electric eye which makes it so the eye will not allow the door to go down note.
Direct sunlight creates interference with the sensors and may keep them from working properly.
A ray of sunlight can trick the garage door opener sensors into thinking there s something in the door s path preventing the door from closing.
Another thing you can do to overcome this problem permanently is to set a cylinder shaped object around each of the sensors eyes which will block the sunlight and prevent it from interfering with them.
If you are in a hurry and need to get your garage door closed right away stand in such a way that you cast a shadow over your garage door s beam sensor but of course don t block the beam itself just the sunlight that is shining on it and then press your remote control so that your door will close.
Disabling the sensor light on a craftsman garage door opener is only temporary and will render the remote controls useless until you reconnect the sensors.
My door has this issue but even cleaning the glass on both sides after putting a solid cardboard piece in the way of direct sunlight so the sensor is always shaded the door still won t shut when the sun is at a certain angle in the sky.
Doityourself has a wonderful explanation.
Knowing how a garage door sensor works allows a homeowner to be watchful for what might affect it.
Sometimes the sensor becomes faulty and needs to be replaced.
When the device detects any person or object in the path of a closing garage door it signals the motor to stop the downward action and switch the motion into reverse to stop the obstacle being crushed.
All garage door openers use a sensor light to prevent the door from closing when an object is in its path.
Figuring out how the shield folds around the sensor can be somewhat tricky so we made this video to show you how to install them.
