This works for my situation, may not work for everyone. My problem was that after Homelink was installed last week it would not automatically close the garage door. Or course I had it set. It worked perfectly to open the door when I came home. I have a Genie brand that is older and has the rotating code type of remote. I also have the sensors at the bottom sides of my garage which sense dogs, etc, walking across the beam when closing the garage door. My situation is I open the garage door with the button on the garage wall and then enter the car and leave. It did not automatically close the door. What I found is that when you get home and the door automatically opens as I enter the garage and the car is blocking the beam sensors so the garage will not close I press the Homelink button on the screen to close the garage. It physically does not close due to the beam sensors being blocked by the car, but I guess the car thinks something, not really sure. After I get out of the car, I close the garage door with the button on the garage wall. I repeat this scenario and now when I leave the garage with the car it shows closing the door in 20 feet and it works. Not sure why, but it is repeatable for me.
