Sewing machines should always run smoothly. A jammed sewing machine is of no use. There are a lot of factors, which can cause jamming of a sewing machine that we will discuss briefly. It is easy to fix them. You can even do it yourself with all the solutions below on a sewing machine jammed wheel. 

The sewing machine jammed wheel can be caused by:

    • A bunch of tangled thread, underneath the fabric you are sewing.
    • Improper tension on the thread.
    • Threading the sewing machine carelessly.
    • Lint or dust particles inside the machine.
    • Fabric getting stuck on the dog feed.
    • Use of low-quality thread.
    • Not oiling the machine for a month or more.
    • Fault in the needle of the sewing machine.
    • Jammed dog feed and presser foot placement.
    • Overfilled bobbin or extra tight bobbin case.

Tangled thread

One of the reasons for the jammed sewing machine is that a bunch of thread is in a tangled mess underneath the fabric. It is because there is not enough tension on the upper thread. 

There is always a misconception when seeing tangled thread under the fabric that it has something to do with the bobbin, as the tangled mess is on the bobbin side. But it is because the machine is not threaded properly, and the sewing machine does not have enough tension to pull the thread up through the fabric.

The solution to this problem is, lift the presser foot and re-thread the machine and needle properly by following the instructions on the manual of your sewing machine, and make sure that you are threading the machine in the right way.

Tension on the thread

Another reason is that the tension on your thread is either too high or too low. To check this, raise the presser foot and try to pull the thread, with the machine threaded all the way through the needle. The thread should flow smoothly, even with a gentle pull. If the thread is too hard to pull, the tension on the thread is too tight or if it is too easy to pull, the tension is too loose. Try to fix the tension disc according to the manual instructions and your machine will work fine.

Threading the sewing machine

Jamming of sewing machine can happen, as sometimes while threading the machine quickly you may skip a step. Maybe due to the neglection of making sure that the thread has passed through the tension discs properly. Always follow the manual, while threading the sewing machine so none of these mistakes will happen.

One of the most common and simplest mistakes most people make is threading the sewing machine with the presser foot down. This will cause tension in the discs, preventing the thread from seating properly between the discs, which will disturb the tension on the thread and make the thread tangled underneath the fabric. So, always thread the sewing machine, with the presser foot lifted.

Lint or dust particles

Sometimes, lint or dust gets stuck somewhere inside the machine, jamming some parts of the sewing machine, thus keeping the machine from working properly. Lint or dust can pile up and accumulate in your machine parts if you do not clean your machine regularly.

For this, turn off your machine first, unthread it, and clean it properly. You can use a brush or a vacuum to clear all the dust or lint that was blocking your machine to function properly. Usual area is around or behind the bobbin, or maybe on the dog feed.

Fabric

Different fabrics leave some floss while sewing the project, which can pile up and cause blockage in your machine. Sometimes the fabric of your project, that you are sewing, can get stuck into the dog feed of your machine that causes jamming. With my personal experience, this is one of the most common factors of machine jamming. To clear this, you should not force it out.

Firstly, lift the presser foot of your machine that is holding the fabric of your project. Then remove the needle so that you will not get hurt in the process. Then slowly pull the fabric out. This will require lifting the fabric enough to snip at the threads and then pull the fabric free of the machine. 

If some pieces of the fabric are left on the dog feed, clean them. Also, check your sewing machine needle, if it is bent then replace it with a new one and, if it is not then you are good to go. Even a slightly bent needle can cause a thread jam and can even break. Your machine would work smoothly.

Poor quality thread

Sometimes the machine does not work properly, because you have not oiled your machine for so long. All machines need to be oiled on a regular basis so that they can run smoothly. Sewing machine should be oiled once a month, and more if you work more often on it. Give your machine one drop of oil daily. 

It should not be too much drenched in oil and not be too dry, and much better to be on the dry side than to be too wet. A drop a day should be perfect for a sewing machine to run smoothly.

Also, if the machine has not been used for a while, you should oil it properly for a whole day or maybe 2 days depending on the time duration, it was not being used. Then place it somewhere in the sunlight. Sunlight helps a lot to smoothen up your machine parts and your machine will work perfectly without getting jammed.

Oiling the machine

Now we have demonstrated all of our choices, it is now evident that we are not only trying to show off the device, but are also highlighting the perks of every machine to help you choose among them.

It is very difficult to choose among the sewing machines in such a large market, but we assure you that these choices are made with full attention to detail and keeping your comfort and value for money first.

We hope you have found this article valuable and we hope that it has helped you on your way to buying the best heavy duty sewing machine for home use. Good luck!

Needle of sewing machine

Sometimes jamming could be caused by the choice of the wrong needle. Make sure you have selected the right type and size of needle for your machine and project that you want to sew. The needle should be sharp for hard fabrics and ballpoints for synthetic fabrics. Fine needles are used for lightweight and heavy needles are used for hard fabrics. 

Also, it happens when you do not attach the needle properly. Check the needle, if it is not loose, or too high or too low. Also, it can twist in your fingers and the side with the groove for a thread to ride through the fabric could be in the wrong position. Re-attach it properly. Your machine would run smoothly like nothing had happened before.

The third problem related to needle is if the needle is bend or broken. Make sure you are letting the dog feed do the work, as forcing the fabric through the machine can bend the needle. Check the needle, if it is slightly bent, replace it with the new one because it could break and a portion of the broken needle is trapped, while you were sewing, between the moving parts that are limiting the motion of those parts.

Dog feed and presser foot

Jamming of a sewing machine could happen because of the dog feed. Dog feed is the chain, with those tiny little teeth, beside the bed-plate of a sewing machine, underneath the food presser, that moves the fabric as needle is making stitches, while you stitch your project.

 Make sure that the dog feed is in the raised position and is gripping the fabric properly. Also, lint or debris int the dog feed area can jam the function of dog feed, preventing them to move. Clean the lint or debris properly, then continue your work.

Bobbin and bobbin case

The overfilled thread on bobbin does not allow it to move freely inside the bobbin case. This causes jamming of the sewing machine. Never let the bobbin to be filled past 1/32’’ margin from its edge.

Sometimes the bobbin case is too tight for the bobbin itself that the bobbin would get stuck inside the case and won’t move that is when the machine will jam and will not work. Do not use force for this. You can simply loosen the nut of the bobbin case and it will work perfectly. in order to see if the bobbin case is not too tight or loose, drop your bobbin into the case and pull the thread out. 

Now suspend your bobbin case into the air, just held by the thread. it should slide down the thread very slowly. If it does not, tug it gently, it should slide slowly. if it does not even after that little tugging, loosen the screw until it does. If it slides down too easily, tighten the screw until it gets fixed. Now you are good to go.
