First check the sensor lights.
Garage door sensor not working in sunlight.
So if the problem seems to occur only during the daytime check to make sure the receiving eye.
Direct sunlight creates interference with the sensors and may keep them from working properly.
Here was one way a homeowner dealt with issues with the sun he moved the sensor on the rail to the end of the track.
The receiving sensor should mounted on the side of the garage door opening that receives the least amount of direct sunlight.
If they re turned on in both the sensors then there is no issue with the power supply.
Sunlight can interfere with the sensors beam and cause them to act as if an object blocks them.
Yeah that won t meet the requirements.
Many years ago sensors weren t common.
If you find the lights turned off in one or both the sensors it indicates that there is a problem in power supply.
Cutout cardboard and secure it around the sensors purchase sun shields that attach to the sensors move the sensors into the garage and out of the sun switch sides the sides of the sensors.
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.
Cycle the garage door through the opening and closing actions using the control on the garage wall.
Depending on the brand.
Clutter or obstructions that block the sensor are the first problems to look for if your door won t close or in extreme cases open at all.
Nowadays for safety reasons most garage doors have them.
Look for small led lights on the sensors.
A common cause of a malfunctioning garage door sensor is lack of power supply.
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.
