How to Fix Sewing Machine Tension Knob

How to fix sewing machine tension knob? One of the most important parts of the sewing machine is the tension knob. Do you know why it is important? Let us tell you why. The tension knob helps you to achieve proper tension. Why should you be concerned with proper tension?

Proper tension on a sewing machine allows for your stitching to be uniform. Proper tension is also essential if you want your thread to move freely on the material that you are working on. If you want to make the back and front stitches on your cloth the same, you would need to maintain proper tension. Hope you have seen why proper tension is important.

To successfully adjust the tension on your machine, there are some basic things about the sewing machine that you need to understand.

You would need to check these on the machine before going ahead to adjust the tension knob.

  • Threading of the machine

The thread guides on the machine as the name implies help to guide the proper way in which the thread is expected to flow from the top of the machine to the needle. The thread guide allows the thread to run smoothly and avoid entanglement. Always check to see that the threading is done right.

  • Check if machine is damaged

Damaged parts of the machine can cause tension on the machine to be off. Be especially careful of not damaging the bobbin. A little drop to the floor from a bobbin can completely damage it, even though the bobbin might still look in perfect conditions.

Also take note of other parts of the machine like the throat plate, thread guides and take-up lever to ensure that they are in good conditions.

What to do when the tension is still off?

It is expected that the upper and lower thread are the same when you are sewing. If you notice that one side is getting tighter or loose than the other, then there is a tension problem.

Here is a simple trick on how you can check the tension of the machine. Get a white piece of clothing and sew on it with two different colors of thread. This would help you to clearly see if there is a problem with the tension or not.

Find the tension knob or dial

Depending on the machine, the tension knob would be located on different sides of the machine. You should check the machine manually to be sure where the tension knob is. The knob usually has numbers around it.

In the case where the tension is loose, you should turn the knob in such a way that the numbers are increasing. Slowly increase the number and test the new tension as you go on. Continue adjusting and testing until the thread is no longer loose.

In the case where the tension is too tight, you should turn the knob in such a way that the numbers are decreasing. Slowly decrease the number and test the new tension as you go on. Continue adjusting and testing until the thread is no longer tight.

Keep testing the tension until you get it right. Remember to test the tension on materials that you do not intend to wear.
