Hello, I have a garage door with a Genie 0.5 hp motor that is having a problem closing and opening. Within the past two weeks it has closed at a slant, i.e. when the door is closed there is 1" to 2" opening on the right side. Also, when I pull the "J" part out and pulled it up to one foot, the door would slide down. When I pulled it to five feet and let go, it stopped but there was a slight slant. Also, it has been making loud noises when opening and closing. In addition, it seems to be jerky when opening and closing. I was wondering what the problem is?
Thanks for any ideas.
