Garage Door Tension

I installed a new garage door. I found online that you want to turn the torsion springs about 31 quarter turns. But just at 20 my door begins to lift. So I have it set at 19 on both sides. The problem is, it's easy to lift at first, but then halfway up it's very difficult. I placed it at 21 quarter turns, but the door does not lay flat on the floor, but it is easier to get it to almost the top, then gets hard to lift. What am I doing wrong?

Your door isn't balanced properly... the spring is too strong for the weight of the door. If your door is 7 foot high it has to have 7 1/2 turns or 30 quarter turns. It's possible you have the wrong drums or wrong cable length. can you post a picture of the torsion set up?

Your reading generic directions on line instead of reading the directions that can with the door!

Maybe it's a used door without directions? I think i would read directions if I had them.

Doorman has it right. Are there any stickers or labels telling you the brand? Did you get the whole door including the tracks and hardware or are you trying to match old to new?

It sounds like you may have installed a new steel door, with the old springs from a wood door. Doorman 2722 has it right, it's the wrong springs.
