Why does my sewing machine keeps jamming? Possible reasons?

Reason no 1: Presser’s foot

The first primary reason why the sewing machine keeps jamming is the presser foot. You must ensure the presser foot has been placed at a smaller gap. Adjusting your machine too much will cause unwanted gaps between the thread on both sides of the fabric.

This will be a double issue for you. It would help if you were careful when it comes to adjustment because too loose and tight conditions can be harmful.

You will not face any issues when using thicker fabrics or multiple layers that require a unique needle. But with thin materials, including satin or silk, ensure the sewing machine is not jamming.

Reason no 2: Bobbin thread

Due to excessive tension on the bobbin thread, most of my sewing machine keeps jamming underneath. Before you touch any of the machine settings, you need to loosen the screw, which loosens or tightens the bobbin casing. It is visible on the machine where you put the bobbin.

Once you feel it has been loosening, you must remove the bobbin and carefully wrap the thread around it. Do it a few times until you are unsure if there is any other slack.

Later on, put it back and once again tied up this screw. This will reduce the tension and jamming for you.

Reason no 3: Lack of tension on the upper thread

Any spool of too tight thread won’t create enough tension on the upper thread. This will obviously cause the sewing machine to keep jamming up easily. You can quickly solve this problem by using a heavier-weight thread.

Make sure you also keep a check on the screws, which are on both sides of the needle plate. Also, check that they are accurately tightened. If not, this can affect the tension on the upper thread.

Reason no 4: Needle is broken

If the needle is not going through the fabric at any cost, this means the needle is broken. Its simple solution is to go for the replacement. But be careful when replacing.

If you get too rough with the needle while inserting it into the new case, it can also damage or break off the bobbin casing. This will create another problem for you.

Reason no 5: Low-quality thread

Using low-quality thread is another primary reason why the sewing machine keeps jamming. A low-quality thread will never help you sew properly and will cause certain obstructions in your sewing process.

Reason no 6: Feed dogs are not functioning properly

The primary purpose of feeding dogs is to help you pull the fabric evenly through the machine. And if they are not performing their duty correctly, the sewing machine will jam.

The problem of feeding dogs can quickly be resolved with the help of a finger or a small brush. Once you have cleaned it properly, test out your sewing machine.
