How to Adjust a Side-Mounted Garage Door Spring?

Side-Mounted Springs

1. Open your garage door fully. Before you can begin working, you must release the tension on the springs. Lift the door until the stop bolt then you cannot proceed any further. For an automatic door:  

·         The door should be opened, disconnect the opener and then unplug the door by pulling an emergency release cord downwards and up again to lock the door into an open position. It will then be able to open the door fully and release the tension on the springs.

2. Secure the door in place. Place a C-clamp beneath the roller’s bottom, or you can use 2 locking pliers (one for each track below the rollers at the bottom). This will ensure that the door does not fall down while you’re working.

3. Remove the spring hook. The spring will be connected to the track hanger with an enormous hook, which is held in place by a nut. When there’s no pressure on the spring, take it completely from its track hanger. Utilize the wrench to loosen the nut that is on the back of the bracket.

·         You’ll now be able to move the hook to a lower or higher hole to decrease or increase the tension.

4. Adjust the tension. To make sure that you get the correct tension, adjust the spring one hole at a time. In case your door is balanced. Moved the hook to the new position and replaced the nut at the back of the hook and made use of the wrench to secure it.  

·         To lessen tension and repair the door that isn’t closing properly or that opens too fast then hook the spring into an opening lower on the hanging track. This will reduce how long the spring is as well as the tension it exerts on it.

·         To improve tension and repair garage doors Raleigh NC that are difficult to close or open too fast, hang the spring to a higher hole in the hanging track. The spring is stretched and also increases the tension it has.

·         To alter the pressure on one of the sides, and to make sure that the door is closing equally and evenly, you can adjust the spring only on the side that has the gap. Reduce the tension in that aspect by connecting the spring to the track hanger through a hole lower than the hanger for the track.

5. Test your door for functionality and balance. After adjusting your spring(s) by one hole, loosen the door, and then test the springs by lowering the door to check what it is like. Adjust the hole again in case your door is closing too fast, slow, or in an irregular manner (with a gap).

·         Repeat steps 1-5 until the door is closing properly and in a consistent manner or until the gap is eliminated.

6. Adjust the cable to make minor tension adjustments. Adjust the cable for minor tension adjustments. The cable in the spring will also be connected either to the hook, or track. You are able to alter this by tightening and loosening knots or the clamp to which it is attached and altering how long the cable.

·         Shorten the cable slightly to increase the tension or lengthen it to lower the tension.

·         Your cable might be connected to the track via an S-hook. If this is the case, move the hook up to an upper hole in order to raise tension slightly, or move it to a lower one to decrease tension.

7. Test the door. Determine if your door is closing and opening exactly as you want it to and make sure it’s properly evenly balanced (closes equally and with no gaps). Keep making small adjustments to the cable and checking the door until it is right.

·         Once you’re done with your adjustments, make certain to get rid of everything that holds the door then pull the emergency cord to unwind the spring. Reattach your door with the opener and then plug it into the automatic door opener.
