That dreaded moment when you devotedly press the machine pedal but it fails to make a sound or move can be totally annoying. In most cases, the sewing machine produces some quality stitches before things get all tangled up and you cannot proceed with your sewing process.

Why Does My Sewing Machine Keep Jamming?
There are multiple reasons why your sewing machine gets jammed. This unwanted scenario can come into play while working on wrong and complicated projects such as sewing denim or other heavyweight fabrics with a small needle. Improper maintenance can also be the cause as well. In a situation where you are sewing with a broken presser foot, your sewing machine is expected to clamp in between a project with time.
In this article, we will be explicitly explaining the reasons why your sewing machine has been consistently getting jammed and how it can be prevented and fixed. Read along and find out.
1. Lack of Tension On The Upper Thread
While you might have been making assumptions that the jamming has been caused by something big and trivia, an insufficient tension on the upper thread might be the reason for this setback. When the tension is not adequate enough to pull the thread through your fabric perfectly, the machine gets jammed and stitches become tangled.
Rethreading your needle would solve this problem. All you have to do is to lift up the presser foot and perfectly re-thread the needle as instructed by the machine’s manufacturer.
2. When Your Machine Gets Clogged
Constant maintenance of your sewing machine is essential to prevent events like this to happen. Your sewing machine can easily get jammed due to excess dust, lint, and other forms of debris. When your machine is not frequently cleaned to prevent this dust and gunk from getting stuck in your machine they can come back and cause unwanted issues to your sewing machine.
When facing a situation like this, the machine should be turned off, and make sure it gets un-threaded and cleaned comprehensively. It is also important to perform the oiling on the necessary metal parts of the machine.

3. Deformed and Broken Needles
A bent or broken needle produces an imperfect stitch and eventually losses its piercing quality when it stops going through your fabrics. A needle in these conditions would prevent your machine from working properly and might eventually stop working totally.
When experiencing such a situation, you should pause work on your project and give your needle a thorough inspection. If it turns out the needle is deformed or has been broken, you can easily replace the damaged needle with a perfect new one.
It is important to take note and use the appropriate needle size that compliments your sewing machine and project as well as it might make your machine jam consistently.
4. Feed Dogs Malfunctioning
When your machine feed dogs are not properly functioning, your sewing machine can easily get jammed. The feed dog is the small teeth that are strategically placed under the needle and presser foot. They are tasked with pulling your fabric when sewing to ensure a smooth sewing process. When the feed dogs get filled with excessive dust, lint, and other forms of debris, the machine tends to malfunction.
To solve this problem, it is required to stop all forms of work you’re doing on the machine and give the feed dogs a proper cleaning by lifting up the presser foot. It is also important to examine the feed dogs and make sure they are properly positioned to ensure a precise grip of fabrics.
You should also inspect the presser foot ensuring it is not set too low over the feed dogs as that might also be the cause of the malfunction. Make sure both mechanisms are perfectly positioned before proceeding with your project.
5. Low-Quality Thread
While you might not have been paying close attention to your thread quality when sewing, a low-quality thread is capable of causing some unimagined problems to both your machine and project. Low-quality thread shreds easily and can effortlessly get stuck in your machine mechanics which can in turn lead to your machine getting jammed preventing you from working.
It can also reduce the performance of your machine thanks to its constant break and knot which causes improper stitch patterns, slows down your machine, and can eventually wreck your project. This can be easily prevented by purchasing good-quality thread endorsed and recommended by the machine’s manufacturer. It ensures smooth stitching and an excellent sewing result.
