There is nothing boring and disgusting for a sewer when the machine gets jammed often. If you have ever experienced this, you will know how awful that is. It is even more disgusting since you do not know the problem and the solution at the same time.

Do you want to know why does my sewing machine keep jamming? Well, to know that, you have to stick to the article and read carefully until the end. We will discuss some common and main problems that cause the sewing machine jamming.

Why Does My Sewing Machine Keep Jamming?

You cannot expect a single reason causing the jamming of your machine actually. There can be many causes for that. If you know the reasons, it will be easier for you to solve it and work with the highest convenience.


Low-quality thread:

So, why does my sewing machine keep jamming? Well, the first reason can be the low-quality thread. A lot of people underestimate the quality of the thread and they install the low-quality thread on the sewing machine. However, due to this problem, you may suffer from the other problems along with the jamming issue as well.

When you use low-quality thread, it causes the shedding of lint that may stick into the machine mechanism and make your machine jam. At the same time, it may break easily and make your machine slow as well. So if you have any low-quality thread, change it and ensure a good quality thread.

Motor issue:

There will be issues with the motor as well. If you are using the sewing machine servo motor, you may have a good speed sewing which is fun for sure. However, this may cause problems with the motor easily. You know, a damaged motor will not run perfectly and that can easily cause your machine jamming.

So before checking any other parts of the machine, make sure you check the motor at first and ensure it is good. If there is a problem regarding the motor, solve the motor issue at first to solve the jamming problem.

Presence of clogging:

Another good reason for jamming your sewing machine is the presence of clogging. When working with a lot of loads, dust and debris may grow in the machine that you do not notice due to the workload. However, if you do not clean the machine after every sewing work, the dust and debris will grow up continuously, which can cause machine jamming as well.

The needle might be broken:

Sometimes, the needle gets broken suddenly and causes a jam in your machine. In that case, you have to carefully check whether the needle is broken or not. When the needle gets broken, it stops the threads from going as well that causes jamming of the machine.

The feed dog is not installed properly:

Another common reason why your sewing machine keeps jamming is the improperly installed feed dog. Other than the wrong installation of the feeding dog, there might be dust and debris as well that reduces the activity of the feeding dog. So check that as well to remove the jamming from your machine.

How to Troubleshoot a Jamming Sewing Machine?

It is really a frustrating time when your machine stops working during a project. That is why you need to know how to troubleshoot the jamming sewing machine. Here is the process for you.


  • Check your thread at first since the problem might be with the low-quality thread of your machine.
  • You can check the dust and debris inside the machine as well since this can be another reason for jamming.
  • If the issue is with the broken or faulty needle, make sure you change it and install it properly.
  • If you have a problem with the feeding dog, change it, or replace it to remove the jam.
  • Check your motor and solve the problem if the problem is with the motor.

Final Thought

So now you know why does my sewing machine keep jamming? There is nothing more frustrating actually than getting your machine jammed during a project. This is a hassle and time consuming to find out the problem and solve it.

So make sure you have checked all the steps we have mentioned above and find out the problem at first. Then solve the problem to remove the jam from your sewing machine. Once you solve the problem, you will have a smoothly running sewing machine that will provide you the fun of sewing.
