Will sunlight affect the sensor eye on liftmaster doors

Hello,
I am not a expert on doors but have ran into a simular problem with my door. Hope this will help.
-Mine would not go down during the day due to sunlight hitting the trip sensors, Take the cardboard tube from a roll of toliet paper and put it over the sensor that is getting sunlight (just a cheap shade).
-Also if you can hold down the door switch inside the garage and the door goes down it is a sensor problem

As I stated before I am not a expert on doors, so please don't give me a bad review I am just sharing what worked for me.

Thanks,

Sounds like a problem with a limit switch or something getting in the way of the electric eye that interrupts for safety reasons. Clean the electric eye transmitter and sensor of debris and cobwebs and make sure the wires are attached properly. Check the operation of the lifting media track or chain. Has it been lubricated recently? If possible, clean the switch in the transmitter in the car, it may be shorting out.

Most photo electric eyes have sensitivity settings. A small dial or screw that can be adjusted.
If there is none, then another trick would be to recess back further from the actual opening, and put is on the wall as far as possible.
Finally, you could add a tube to act as a sunshield. They probably have one that can be special ordered for it.
And it even that does not work, consider taping a sheet of polarized film over it, like a single sunglass lense.

Your sensors are defective and need to be replaced.

Your safety reversing sensors must be connected and aligned correctly before the garage door opener will close. An obstruction in the path of the sensor will also cause your door to not close.
This sensor is an electronic beam, which is sent between two sending and receiving “eyes”. These eyes face each other and are located just inside your garage door. They may need to be adjusted so the beam from the sending eye is properly detected by the receiving eye. Once the receiving eye “sees” the beam from the sending eye, a green indicator light will glow on the eye.

WOW I NEED TO RAISE MY RATES!!
I DON'T KNOW THE RAYNOR PRODUCT. HOWEVER, WITH MOST OTHER BRANDS THE PROBLEM YOU DESCRIBE CAN BE SOLVED BY SWAPING THE POSITION OF THE SENDING RECIEVING EYES THUS GETTING THE ONE THAT IS BEING AFFECTED IN THE SHADE
HOPE THIS HELPS

You need to do is shade the eyes some how for th door to work. What I did was remove them and put them up by the opener so the sun does not get to them.

The safety eyes are either installed wrong, or you have the wrong type. Craftsman (liftmaster) has what they they call old style and new style safety eyes. You can not interchange the types.

You have a photo eye (sensor) issue as you suspected. Be sure both green lights are on.  If one is flashing or is off, the photo eyes need to be realigned or there may be a wire shorting out (check for staples in the wire) to the photo eyes.  Sunlight can also be an issue.  The photo eyes might have to be moved away from the opening to be out of the sunlight.

The sensor eye - or more likely, the other end, the sensor light - probably got knocked out of alignment. The eye should have an LED on it - possibly one that glows green when it's ready to close or red when it's obstructed or out of alignment. Try adjusting the light until the LED on the receiver glows green.
