Are you wondering why does my sewing machine keep jamming? Sewing machines are an essential tool for any sewing enthusiast. They make assembling fabric, thread, and needles into a finished garment faster and easier than hand stitching. Your sewing machine keeps jamming, and you’re frustrated. You’ve been using the same needle, thread, bobbin, and fabric for a while now, but it just won’t sew right. The stitches are uneven, come out too short or too long, or the threads get tangled up in knots. It’s also hard to push down on the foot pedal because something catches underneath it. Sewing machine jamming can be caused by various factors, including poor quality needles, tangled thread, loose spool holder, or insufficient bobbin tension.
Why Does The Sewing Machine Keep Jamming – Causes And Solutions
What could be going wrong with your machine? Let’s take a look at some of the common causes of why sewing machines keep jamming.
Your sewing machine keeps jamming: the needle is dull
The needle is the most essential part of your sewing machine that keeps running smoothly. If you use a dull needle, then it will damage your fabric and cause stitches or thread to get stuck underneath it when pressed down on the fabric. If you are experiencing jamming in your sewing machine and the needle is dull, you should replace it immediately.
The sewing machine is dirty
If you notice any leftover thread in your sewing machine, it may also be jamming. Remove all remnants of thread from inside your machine and make sure there aren’t any loose bits of thread lurking around. You may also want to take a closer look at your sewing machine. It might be jamming because a foreign object is underneath the foot pedal. Make sure that nothing is caught under the pedal and if possible, try working from another angle so that you can see from behind what’s causing the jamming.
The needle is bent or damaged
It’s important to check the condition of your needles frequently because if they’re bent or broken, then they can damage thread and fabric while sewing. If you notice that the tip of your regular sewing machine needle has become bent, then you should replace it immediately.
The bobbin case is dirty or full of lint
If your sewing machine has a jamming problem, then you should check the bobbin case to see if it needs cleaning After using fabric for a while, particles will accumulate in your bobbin case. This could lead to uneven stitches and thread jams. Make sure that your bobbin case is clean and free of lint. You can use a brush to remove any dirt, debris, or dust that has collected inside the bobbin case.
The spool holder is loose or damaged
Your spool holder affects the tension and movement of the fabric as you sew. If it’s not working properly, then these issues could lead to thread jams and uneven stitches. If your sewing machine keeps jamming, then check if the spool holder is loose. You can tighten it with your fingers or use pliers if necessary. Your sewing machine keeps jamming, but it’s definitely not the needle, thread, spool holder, bobbin case, or any foreign objects underneath the foot pedal.
The bobbin tension is too high
If your bobbin tension is too high, then it will cause the thread to unravel and knot up. The higher the tension, the tighter the stitches and vice versa. Lowering or loosening your bobbin tension can help you sew with consistent results. Loosen your bobbin enough so that there’s a small loop beneath your finger when you pull the thread up. Your bobbin tension is too low if it’s hard to pull the thread upward. Increase your bobbin tension until there’s a small loop beneath your finger and watch as the stitches tighten.
The Bobbin tension is not correct
If you’re not sure about whether or not your bobbin tension is correct, then you can try putting in a different bobbin. If your machine sews without jamming with the replacement bobbin, then your old one was most likely causing the issue in the first place. If you can’t find another bobbin to test with, then it might be time to buy some replacement bobbins and use them one by one until you find the difference-maker.
The Sewing machine foot is misaligned
If your sewing machine foot is misaligned, then it will affect your ability to sew straight lines and curves. It could also lead to thread jams and skipped stitches. You can test this out by moving your needle to the left and right of the foot pedal. If your machine continues to jam, then you should take it in for repair.
The feed dogs’ speed is inconsistent
If your feed dogs are not working at a constant speed, then the feeding process will be uneven. This lack of consistency could lead to thread jams and wonky stitches. The best way to check if your feed dogs are causing the sewing machine jam is by lowering your presser foot while you’re still sewing. If the feed dogs’ travel speed is too fast, then the thread will keep on piling up until it’s impossible to push. However, if your presser foot falls down once you lower it, then you’ll know that your feed dogs are working just fine.
The feed dogs’ take-up lever doesn’t work
When threading your sewing machine, you might have noticed that only one side of the thread spool has a tiny take-up lever attached to it. The other side is smooth and doesn’t have a lever. The Take-up Lever’s job is to keep the thread from unwinding too quickly or too slowly. It also keeps tension on the thread so that it feeds through your sewing machine at a uniform speed. A broken take-up lever can cause thread jams, skipped stitches, and all sorts of sewing malfunctions. If the Take-up Lever is broken or damaged, then you’ll need to replace it. Otherwise, your thread will keep hanging and causing issues with your sewing projects.
The machine’s Bobbin case is worn out
When you’re replacing a bobbin case on a sewing machine, then there are several things to watch out for. It’s possible that your bobbin case is too worn out and needs replacement as soon as possible. First, take a look at the bobbin case to see how much thread it holds. If there’s still a lot of room left, then you should replace it with a new one. Otherwise, it can cause tension issues and thread jams. Finally, try out a few different brands of bobbin cases if yours is worn out. Depending on the machine’s manufacturer, some bobbins cases work better than others.
The thread tension is incorrect, or you are using the wrong type
You may have set your thread tension incorrectly because there are two different dials for this on most sewing machines. One controls the top thread tension and the other controls the bobbin thread tension. Adjusting the tension will control the amount of thread being pulled through, which can affect how tight your stitches are and if they’re even. If you have a bobbin case instead of a drop-in bobbin, then you should adjust the bobbin tension to fix this problem as well.
Using the wrong thread for the project
Many sewing machine jams happen because the wrong type of thread is being used. If you are using a heavy-weight or specialty type of thread, then this could be causing the machine to jam because it’s too thick for the sewing machine needle.
Check for missing needles
If you are using a machine that uses two needles, then ensure that both are installed and correctly placed. It can also help remove the needles and clean underneath it and around the bobbin case and spool holder. This prevents problems like jams or thread getting caught where no needle is present.
Check for thread tangles
When you remove your project from the machine, it’s a good idea to check for loose thread. This can happen when the bobbin is inserted improperly or if there is any kind of tension problem with it or the top thread. It’s essential to go over every inch of your work and cut away anything that isn’t attached to your project. There could also be thread tangles if you aren’t using a sewing machine with a built-in cutter like an overlocker. Using one of these machines is always better and never cut your thread by hand because they can cause problems.
Check for Sewing machine damage
Another reason that the needle may be jamming is that there is a problem with your sewing machine. This can usually happen when you have been using it for a long time, so check the whole body of your machine and remove any obstructions that could be in the way or damage caused by mishandling. You should also look at the needle’s position in your machine and ensure it’s not bent or out of place.If your sewing machine has a problem, you may need to do some maintenance on it. Check if the tension disks need to be cleaned and check clear any debris around the bobbin case or spool holder, as well as remove thread tangles from inside them.
The thread is old or damaged
If your thread has frayed ends, then it may not be able to feed through the machine correctly. The needle can get caught in these loose threads and cause a jam which will stop it from sewing. It’s always best to have a new thread on hand so that you don’t have this problem while sewing something important.
If the thread has been damaged, then you should replace it immediately because it could damage your machine even if the needle doesn’t get caught in it.
The most common cause of sewing machine skipped stitches is using the incorrect needle. The needle’s guideline is that you should use a ballpoint needle for knit fabric and a sharp one for woven cloth. However, if you swap needles frequently or force the material into the device rather than feeding it in, this might result in bending needles. When performing straightforward mend, it’s not difficult to understand which needle to use and when. Make sure you know how to utilize each one correctly.
You’re using the wrong thread for the job
Using the wrong type of thread can cause problems that you may not be able to fix easily. It’s important to always use high-quality thread which is well made because it will be stronger and won’t break easily while sewing. Cheap thread is usually much weaker than this so stick to buying good quality items to avoid problems with your work.
The motor failure
The motor fails to function. The sewing machine’s motor is a part that provides the power for the needle to move and sew. It can fail due to a variety of reasons, but this generally means that the machine is broken and it will need to be repaired or replaced. In some cases, you may be able to get it working again by opening up the machine and cleaning out all of the thread inside it.
The fabric you’re sewing is too thick or heavy
Thread can easily break if you are using it on heavy fabric. It’s essential to only use the right needle for your project, and if this doesn’t work, you may need to change it to a thicker type. This will hold the thread well without any problems occurring while sewing. If your fabric is too thick for a standard needle, you should use a leather or denim one designed for heavyweight projects.
What Tension Should My Sewing Machine Be On?
Different types of fabric will need different tensions. Generally, a sturdy fabric will require a lower sewing machine tension, while softer fabrics have a higher one. This is because too much pressure can cause the needle to break and be unable to create the thread path that is needed for sewing. You should start by experimenting with various tensions until you find a level that works well with your project type.
On many machines, this will usually be an adjusting wheel located on the front or side of your machine – usually near where you load it with thread and bobbin. Depending on what type of material you are working with, there may be markings for high-medium-low-extra low tension areas on the device itself, which would make setting this more standardized. If the tension seems to be off on your machine, try winding the tension wheel in one direction or another until you get it into place.
