In some cases basic exposure to the elements along with temperature fluctuations may result in bowing.
Garage door bows when opening.
I believe there will always be a slight bowing as the pushing and pulling of the door exerts pressure on the rail.
Sometimes a garage door won t open or close for one reason only the operator has no power connection.
One of the best features of garage bow is that you are able to open and close your garage door by simply cutting the magnet along the breaks in your garage should only be 3 4 cuts.
My only suggestion is the ensure that the door operates properly and easily without the gdo and then re connect the door.
In other cases the weight of the garage door in conjunction with an automatic garage door that is attached to the center of the door may be the cause of bowing.
Door openers that attach to doors pull on the upper middle of the top section causing the center of the section to bow over time.
My gdo rail bows slightly when opening and closing as well.
In the funniest of scenarios the problem will simply be due to an unplugged power cord.
Doors without openers have no brace preventing warping and swelling at the top of the section.
