5 Reasons Why Your Sewing Machine Keeps Jamming
1.Lack of tension on the upper thread
However, a common problem that can frustrate many sewers is when the machine keeps jamming. One of the most common causes of this issue is a lack of tension on the upper thread..
Tension is crucial to the sewing process. It refers to the amount of pull or resistance applied to the thread as it passes through the machine. If there is too much or too little tension, it can cause the thread to break or become tangled, resulting in jamming.
When there is not enough tension on the upper thread, it can cause it to become loose, resulting in lumps or knots on the fabric’s underside. This issue can occur for several reasons, such as incorrect threading of the machine, a worn-out needle, or an issue with the bobbin. Additionally, using the wrong type of thread for the project can also affect tension.
The Solution
To solve this problem, start by rethreading the machine, ensuring that the thread is properly positioned in the tension disks and through the needle. Check the needle to make sure it’s not bent or dull, as this can cause the thread to break. Replace the needle if necessary. Additionally, make sure that the bobbin is correctly inserted and that the thread is correctly wound onto it.
Another solution is to adjust the tension on the machine manually. Most machines have a tension dial that can be adjusted to increase or decrease tension. Adjust the tension gradually, testing the stitches as you go until you achieve the desired tension.
2.Your machine is clogged at some point or place
There are several reasons why your sewing machine may keep jamming, but one common cause is that the machine is clogged at some point or place.
Sewing machines are made up of many small moving parts that work together to create a stitch. Over time, lint, dust, and other debris can accumulate in the machine, causing it to jam up. The most common place for clogs to occur is in the bobbin area.
The bobbin is the small spool of thread that sits beneath the needle plate and feeds thread to the needle. If the bobbin area becomes clogged with lint or other debris, the thread can’t move freely, and the machine will jam.
The Solution
Fortunately, the solution to a clogged sewing machine is usually straightforward. The first step is to clean the machine thoroughly. This involves removing the needle plate, bobbin case, and any other parts that can be easily removed. Use a soft brush or compressed air to remove any lint or debris from the machine. Be sure to clean the bobbin area thoroughly, as this is where clogs are most likely to occur.
3.The needle is deformed or broken
One of the most common reasons why a sewing machine may keep jamming is due to a deformed or broken needle. Needles are an essential component of a sewing machine, and they are responsible for stitching the fabric together. Over time, needles can become worn out, bent, or even break due to various factors, such as incorrect needle size or type, incorrect threading, or excessive use.
A deformed or broken needle can cause the sewing machine to jam by preventing the fabric from moving through the machine smoothly. When the needle is not functioning correctly, it can cause the thread to break or become tangled, leading to a jammed machine. Additionally, a bent needle can cause damage to the sewing machine’s hook and other components, which can further complicate the issue.

The Solution
If you suspect that your sewing machine’s needle is deformed or broken, it is essential to stop sewing immediately and inspect the needle. First, ensure that the needle is correctly inserted and that it is the right size and type for the fabric you are working with. If the needle is damaged, replace it with a new one. It is also important to check the sewing machine’s manual to ensure that you are using the correct needle for the specific fabric type.
Regularly changing your sewing machine’s needle can help prevent it from becoming damaged or worn out. A general rule of thumb is to change your needle after every 8-10 hours of sewing or when starting a new project. Additionally, always ensure that your needle is inserted correctly and securely, as a loose needle can cause significant damage to the sewing machine.
4.The feed dogs are not functioning properly
If your sewing machine keeps jamming, it can be a frustrating and time-consuming experience. One of the most common causes of this issue is when the feed dogs are not functioning properly. The feed dogs are the little metal teeth that protrude from the sewing machine’s surface and move the fabric forward and backward as it is being sewn. When these feed dogs become misaligned or stop moving altogether, it can cause the fabric to get stuck in the machine, leading to jams.
There are a few reasons why the feed dogs may not be functioning properly. One common cause is that they have become clogged with debris such as lint, dust, or thread. When this happens, the feed dogs cannot grip the fabric properly, causing it to get stuck in the machine. To prevent this from happening, it is important to regularly clean your sewing machine, particularly around the feed dogs.
Another reason why the feed dogs may not be working is that they have become worn down over time. If this is the case, you may need to replace them. This can be done by a professional sewing machine repair person or you can purchase a replacement feed dog and install it yourself if you feel confident in doing so.
The Solution
To fix the issue of feed dogs not functioning properly, you can try cleaning them with a soft brush or cloth. If this doesn’t work, you can try adjusting the feed dog height or replacing them altogether. You may also want to check the user manual for your sewing machine to see if there is a setting or feature that needs to be adjusted to re-engage the feed dogs.
5.Low quality thread
One common reason why a sewing machine keeps jamming is due to the use of low-quality thread. Low-quality thread can be made from weak and poorly spun fibers, leading to inconsistencies in the thickness of the thread. This can cause the thread to break or get caught in the machine, resulting in a jam.
The Solution
To solve this issue, it is important to invest in high-quality thread made from strong and well-spun fibers. Look for thread made from cotton, silk, or polyester, as these materials are known for their strength and durability. It is also important to choose thread that is the right weight for your project. If the thread is too thin or too thick, it can cause tension issues and result in a jam.
Another solution is to ensure that your machine is properly threaded and that the tension is set correctly. Improper threading or tension can cause the thread to become tangled and result in a jam. Be sure to follow the instructions in your sewing machine manual and double-check that everything is in the right place.
Regular maintenance of your sewing machine can also help prevent jams. Clean the machine regularly to remove any debris or lint that can build up and cause issues. Use a high-quality lubricant to keep the machine running smoothly and to prevent friction that can lead to thread breakage.
In summary, low-quality thread is a common culprit when it comes to sewing machine jams. To prevent this issue, invest in high-quality thread made from strong and well-spun fibers, ensure that your machine is properly threaded and the tension is set correctly, and maintain your machine regularly. By taking these steps, you can avoid frustrating jams and enjoy a smooth sewing experience.
