Decide the solution 

Basic solution for any problem can be increasing or decreasing the spring tension on the door. You will need to:

  • Decrease the tension when the problems are the door isn’t fully close, hard to close, or opens too quickly.
  • Increase the tension when the problems are the door is hard to open or closes too quickly.
  • Adjust the tension on one side (or where the gap occurred) when your door is closing un

Set up your tools 

You need to assemble some basic yet essentials tools and safety equipment for this job. Gloves, safety glasses, and a hard hat will be highly need as the safety equipment. Meanwhile, as to the tools, you need to prepare a sturdy ladder, a C-clamp, an adjustable wrench, and a marker or masking tape.

Adjusting Side-Mounted Springs

Fully open the garage door 

Before starting the work, you have to release the tension on the springs by opening the door until it hits the stop bolt. After that you are allowed to go any farther.

For an automatic door, you need to open the door, disconnect the opener, and unplug the door from the opener by pulling the emergency release cord down and back until the spring secured in the open position. You will then can open the door fully and free the tension on the springs.

Keep the door secured in its place

You can position a C-clamp beneath the bottom roller, or else employ two locking pliers (one on each track below the bottom rollers). This will definitely make sure that the door won’t fall while you are working.

Remove the spring hook

As stated above, the spring is attached to the track hanger by a large hook which has a nut to keep it in its place. Once you find no more tension on the spring, take it away from the track hanger. For doing so you can use the adjustable wrench to remove the nut on the back side of the bracket.

After then you are able to move the hook to a lower or higher hole hence you can lessen or rise the tension.

Adjust the tension

Adjusting the spring by one hole at a time can give a certain measurement that you reach the correct tension. In this case, adjust both springs evenly, one at a time, if your door was balanced. After the hook has been moved to its new location, you can take off the nut on the back and tighten the hook into its place with the help of a wrench.

  • To lessen the tension and repair a door which cannot fully close, is challenging to close, or opens too quickly, you need to hook the spring onto a lower hole on the track hanger. This will trim down the length of the spring and the tension on it.
  • To rise the tension and mend a door which hard to open or closes too quickly, you have to hook the spring onto a higher hole on the track hanger. This will stretch the spring and raises the tension on it.
  • To adjust tension on one side and fix a door that cannot close evenly, you simply can correct the spring only on the side where it leaves a gap. And, you can reduce the tension on that side by hooking the spring onto a lower hole on the track hanger.

Check door’s functionality and balance

After carrying out spring(s) adjustment by one hole, you may unclamp the door and test the springs by letting down the door to see how it feels. If your door is still closing too swiftly, slowly or unequally (leaves gaps), you can perform another single-hole adjustment.

If necessary, repeat the steps until your door can close correctly and evenly, or until there’s no more gap.

Adjusting the cable for minor tension adjustments 

The spring has a cable which is attached to a hook or the track. Adjusting it can be done by tightening or loosening the knot or the clamp adjoining it and by squeezing the cable’s length.

Shortening the cable can somewhat raise the tension, while lengthening it means slightly reducing tension.

Also, you may find this cable is attached to the track by an S-hook. If it’s the case, put the hook to a higher hole to turn up the tension slightly or to a lower hole to lessen tension slightly.

Test the door

Check to see whether your door is opening and closing the way you would like it or not. Make sure that it’s balanced (closes evenly and leaves no gaps). You may proceed by carrying out minor adjustments with the cable and testing the door until it’s properly working.

After finishing your adjustments, make sure to take away anything which has kept the door secured in place. To release the spring, you can pull on the emergency cord. You need also to reattach the door to the opener, and plug in the automatic door opener.
