Common Causes of Sewing Machine Jams
Sewing machines are an essential tool for many households and professionals alike. However, they can often jam due to various reasons, resulting in frustration and wasted time. Regular maintenance and understanding the common causes of jams can help prevent or minimize the occurrence of this issue.
Worn or Damaged Parts
Sewing machine parts are prone to wear and tear, especially with frequent use. Worn or damaged parts can cause the machine to malfunction, leading to jams. Some examples of parts that can cause jams include:
- The hook: The hook is responsible for picking up the thread and carrying it under the presser foot. Over time, the hook can become worn, causing the thread to hang up or twist, resulting in a jam.
- The needle bar: The needle bar guides the needle through the fabric. A worn or damaged needle bar can cause the needle to bind or get stuck, leading to jams.
- The bobbin case: The bobbin case holds the bobbin in place. A worn or damaged bobbin case can cause the bobbin to shift or become loose, resulting in jams.
To resolve jams caused by worn or damaged parts, replace the affected parts with new ones.
Improper Threading
Improper threading is another common cause of sewing machine jams. If the thread is not properly threaded or wound around the spool, it can cause the machine to jam. Some tips to prevent improper threading include:
- Double-check that the thread is wound in the correct direction.
- Make sure the thread is not tangled or knotted.
- Thread the machine according to the manufacturer’s instructions.
To resolve jams caused by improper threading, carefully unwind the thread and re-thread the machine correctly.
Tangled Threads
Tangled threads can also cause sewing machine jams. When the thread becomes twisted or knotted, it can get caught in the machine’s mechanisms, causing a jam. Some ways to prevent tangled threads include:
- Use a thread conditioner to prevent tangling.
- Regularly clean the machine to prevent lint and debris buildup.
- Thread the machine in a well-lit area to avoid mistakes.
To resolve jams caused by tangled threads, carefully unwind the twisted thread and re-thread the machine correctly.
Damaged or Distorted Threads, Sewing machine keeps jamming
Damaged or distorted threads can also cause sewing machine jams. When the thread becomes damaged or distorted, it can cause the machine to malfunction, leading to jams. Some ways to prevent damaged or distorted threads include:
- Only use high-quality threads that are resistant to damage.
- Avoid using old or worn-out threads.
- Follow the manufacturer’s instructions for thread usage.
To resolve jams caused by damaged or distorted threads, replace the affected thread with a new one.

- Check the needle’s shank for any damage or excessive wear. If it’s damaged, replace it with a new one.
-
- Use a new needle every time you start sewing a new project. This will help prevent the buildup of lint and debris on the needle.
Spindles
The spindle is the part of the machine that holds the bobbin in place. Over time, the spindle can become worn or damaged, leading to jams and other issues. To inspect the spindle, look for any signs of wear or damage.
- Check the spindle for any signs of wear or damage. If it’s worn or damaged, replace it with a new one.
-
- Make sure the spindle is securely tightened to the machine to prevent loose threads and jams.
- Use a new spindle every time you start sewing a new project. This will help prevent the buildup of lint and debris on the spindle.
Bobbin Cases
The bobbin case is the part of the machine that holds the bobbin in place. Over time, the bobbin case can become worn or damaged, leading to jams and other issues. To inspect the bobbin case, look for any signs of wear or damage.
- Check the bobbin case for any signs of wear or damage. If it’s worn or damaged, replace it with a new one.
-
- Make sure the bobbin case is securely tightened to the machine to prevent loose threads and jams.
- Use a new bobbin case every time you start sewing a new project. This will help prevent the buildup of lint and debris on the bobbin case.
Other Parts
In addition to the needle, spindles, and bobbin cases, other parts of your sewing machine may also wear out or become damaged over time. Some common parts to inspect and replace include the hook, tension discs, and presser foot.
Remember to always refer to your machine’s user manual for specific instructions on how to inspect and replace these parts.
