Garage Door Opener
I have a sears 1/2hp garage door opener. It has been working perfect for the past 3 months and now when it closes it goes all the way to the ground and then opens back up. I have messed with the up and down adjustment knobs and it has made no difference. When It gets to the ground it does look like it is still trying to go down a litte further cause the overhead track kind of binds a little and bows up. Suggestions please!!!!
