I'm preparing to install a new garage door opener on a 2-car garage with roll-up metal door. I'm concerned that the door may not be properly balanced, and that may have led my old opener to wear out (it was a 14-year-old Stanley, so it may have just been old age too).
The new opener instructions states that if I open the door 3 to 4 feet, it should stay open. My door will stay open if I open it about
3 1/2 feet, so it meets that criteria. But when the door is fully closed, I have to pull pretty hard to get it to start to open, and it only starts to get easier when I've raised it a couple of feet. I put my bathroom scale under the door, and I weigh 35 pounds on one end, 42 pounds in the middle, and 44 pounds on the other end.does this seem normal? thanks, paul
