Garage Door Opener Won't go down

My garage door opener will open fine. It won't even start down to close. It doesn't matter if I use the remote or the wall switch, it will go up, but not down. I checked the electric eyes, and they seem fine, and moving them around slightly doesn't help.

Something in the door may be broken, since this happened after the door itself got in a bind and we had to replace it. But the opener was never removed, and the track screw seems to be running fine.

It's a Genie with a screw track.

Replace the opener

With the door in the down position I would disconnect the trolley by pulling the red cord and run the opener up. The trolley will move toward the motor as if the door is going up. Then push the button again to see if it will move down. If it moves fine when the door is disconnected the door may be tweeked or binding. This can eliminate the door as being the problem. If it will not work in this situation then it is above my head.

Thanks for the answers. The door is working fine. I keep it dsconnected from the motor trolly, and operate in manually now. It's a new door, so it's rolling fine.

And the motor seems to work, because it will go one direction but not the other. But, I guess it's possible it just needs replacing.
