Garage door will not close one I installed Chamberlin

I just bought the Chamberlin garage door openers so that I can open and close the garage door remotely. Once I installed it and synced it to my Liftmaster garage door opener it would open the door but not close it. In fact the only way I can get it to close is to hold down the button on the wall. It was working fine before I installed it? I noticed the led is blinking 3 times if that helps. Any ideas what is causing the problem. Maybe it is not compatible with My Garage door opener? also I unplugged it and took the sensor of the door and same results.

William, 

You noted that it will not close the door. Does it always work on opening the door or does it not work at all? I've had some trouble in the past and no it is not perfect for me today but what I found seemed to fix this issue is placement of the gateway. It seemed like direct line of sight was required for mine to consistently work. Since I have to doors to control placement was tricky for me. One way to test the placement is unmount the until from the joists (if that's what you did) and try pointing directly to the door. If that opens and closes then I would bet you have a placement issue.
