Adjusting an Out-of-Balance Door

Start with the door about 3 feet above the ground. Move it up and down until you find a place where the door stays when you let go. If that point is more than 4 feet or less than 3 feet above the ground, you'll need to balance the door.

Make sure you adjust the door while it's open. This takes the pressure off the door springs. Put a ladder under the door to make sure it won't close accidentally while you're working on it.

Make sure the spring is completely free of tension, then remove it from the track hanger. If the door was closing too quickly, move the spring to the next higher hole on the bracket. If it was opening too quickly, move it to the next lower hole. Move both springs, and retest the balance.

Close the door, and check with a level to make sure the door comes down evenly on both sides. If it doesn't, adjust the spring tension on each side of the door until it does.
