Depending on the brand.
The photo eye components consist of two pieces that align face to face across each side of the garage door roughly four feet above the ground.

If there s something blocking the door from closing all the way a full close will be impossible.
One or more of these reasons is likely responsible for your garage door closing partially but not all the way.
Try the wall.
The sensors may not be aligned properly.
These obstructions can include anything like a garden tool a lawn chair or anything else in the way.
It could be that they are just barely aligned but the vibration from closing causes them to intermittently break the beam.
The first step to take when your garage door won t close is to look around and do a visual check.
Then try closing the door manually.
If something is blocking the safety beam then the garage door will not close.
Could also try disconnecting the door from the chain should be a pull cord that allows this.
First check the sensor lights.
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.
