Manual door help!

[ericstan]

Hi guys, new to this site. I just installed an 18x9' garage door at my house that I picked up used from a guy. The door is a steel non insulated with low overhead clearance track and torsion springs. The door sits nicely in the tracks and operates sweet with loaded springs. However, I noticed now that I have turned the springs even though it goes up nice, it doesn't close down enough to make the top panel sit flush like the rest. It is important to know that I reduced the height of this door by removing one of the 21" panels to fit my opening. If I take some of the torsion pressure off by reducing the amount of turns it seems to lay down again but then I can't lift the door. Any help would be great!

May I suggest you update your location as in future you may find that helps you when you have specific questions that affect you. Specially given the forum has a very global membership. Often you will find subjects may get different answers depending on locations and regulations.

Welcome to the GJ.

I suggest you ask that again in General Discussion for a better answer.

The spring has to be matched to the weight of the door. If you had a 5 section door before, you've removed 20% of the weight, so you need a spring that's 20% weaker. If you take your existing spring to a garage door expert (s)he'll be able to get you the spring you need. If you just remove some tension on your existing spring, the tension will balance the door at only one point.
