Hello,
I could use some advice on how to fix my garage door problem that started a couple of days ago. It doesn't happen everytime, but the garage door will almost completely open and suddenly stop. I usually have to press the button to close it and try again. Sometimes it takes 2 or 3 tries until it completely opens. I have noticed it stops at the exact point everytime, and when it does completely open, when it passes that point of getting stuck, a loud "bang" sound comes from the door. The house is only 4 years old, so I figured it is not wear. I have not greased the track, wheels or hinges since it was installed..could that be it? I would really appreciate some advice. Thanks!
