Two days ago I came home from work and opened the garage door normally, once my car was in the garage and I tried to close it, it wouldn't close. It makes two brief humming noises, but it wouldn't close. Everything seems to be fine, such as the springs and the door and track seem fine. It won't work with the remote or with the control on the wall. Does anyone know what could be the problem? Any help would be greatly appreciated. If you need to know the model number or any other information I can certainly get that. Thanks
