Breaking thread usually results from mis-threading or tension too tight. Install a brand new needle. Try a different brand of thread (AVOID old or bargain bin threads!). Set the tension at the midway point between high & low number.

Does it sew fine for a couple of inches and then pop? Watch the thread, does it get tight between the spool and needle before it breaks? If so, the thread is hanging up somewhere--is there a nick or slot on the thread spool itself that is catching the thread?

Remove the thread completely and re-thread from the beginning. When threading, ALWAYS RAISE the presser foot so the thread will seat in the tension disk. Verify that the thread path is correct and that nothing has been threaded out or order or missed. Check that the thread is not snagging on a burr or nick.

Confirm that the correct needle is being used for the thread and fabric, ie the thread is too thick for the needle's eye. Usually, the symptom is shredded or frayed thread at the needle eye.
All About Needles

There could also be a burr snagging the thread at the needle plate or around the bobbin area. Wrap a finger with fine fabric (old hosier, chiffon, silk) and run your finger around the needle plate and bobbin area. If it snags, you know where to look. If it's a small burr, it can be smoothed (gently!) with a fine emery board or sand paper. If it is a large burr, it should be taken to a technician or a replacement part installed.

Check your threading path with your manual. If, you look up your manual online at it can be made larger and you may spot your mistake easier.

SOURCE: janome s950 sewing machine top thread keeps breaking?

Well, Madalyn, when was the last time you oiled the machine. Go to for tips on that and on tension, timing, cleaning the shuttle race, etc. , but now, let's talk about this particular problem you are having: it sounds to me like you could use a new needle of the correct size for the type of fabric/weight of fabric you are sewing. Also, sometimes sewists think they have that needle all the way up in the needle bar shaft, but...oops! no, it's not, and sometimes they also forget that the flat side goes toward the back of the needle bar. Also, sometimes sewists (not necessarily YOU, Madalyn, but SOME sewists, forget to turn the handwheel toward themselves and keep that presser foot in the UP position when they thread the machine. What happens? Yep! The tension discs do not open all the way up for thread to locate the tension discs and creates a problem. Make sure you clean the shuttle, the feed dogs. No big deal. Relax, get the little brush. Much success!

My machine keeps on breaking the thread

You don't state which thread is breaking, so will assume it is the top thread.

AVOID using old or bargain bin thread!

Remove the thread.
Install a brand new needle.
ALWAYS RAISE the presser foot and rethread from the beginning.
Verify the thread path is correct.
Set the top tension to the midway point (this may need to be tweaked for your individual machine).

If it still breaks, then the thread may be catching somewhere, perhaps on the needle plate or in the bobbin area. When a needle deflects, it will sometimes strike somewhere and cause a burr or rough spot. That rough spot will then catch the thread and cause it to break or shred.

Wrap your index finger with a fine piece of scrap fabric like chiffon, nylon knit, or silk. Then run your finger around the surface (top & bottom) of the needle plate and in the bobbin area. If the fabric catches, there is a burr. Also check the hook/shuttle as this where a lot of burrs are located. If it is a small burr, it can be smoothed with a fine emery board or emery cloth. It the burr is large, the part may need to be replaced.

How do I stop my tread from popping on my Brother (17 stich) sewing machine?

Breaking thread? Presumably the top thread? AVOID old or bargain bin threads. The upper tension is too tight or the thread is not properly seated in the tension disk, the needle is defective or the needle, needle eye/scarf is not the best choice for the fabric/thread being used, there may be a snag in the bobbin area that is catching the thread. Make sure the thread is not catching on the spool's thread notch.

Why is my thread breaking

Does about 8 stiches, and the red light flashes and it stops

This indicates a thread break, but if thread is not broken I would rethread the top as there is a thread break sensor on the take up spring that could have been missed in threading. If that does not solve then I would have a look at take up spring and attached sensor

Mb4 false thread break

found the problem and unfortunately it is not something that i can fix and will have to take it to the repair shop on monday. The thread spring for that needle is broken and flopping around a little bit more than it should. From what i have been able to find on the web the up and down motion of the thread spring is used to sense if the thread is actually being pulled through the machine. this is how it detects if either the top thread or bobbin thread is broken. top thread not advancing and pulling the thread so that the thread spring goes up and down indicates one of the two is busted. Had a lot of responses to this on another forum with one person even sending pictures of what to look for and apparently this is a very common problem if the thread is not properly put through the eyelet of the thread spring and gets caught in the wire wrap of the thread spring. It just pulls it and breaks it. getting old and the eye sight is fading so just bought a lighted magnifying glass lamp to stop me from hurting my sweet little machine. So if you have one needle that is constantly giving you a false thread break indication this is where to look

thanks everybody for the rest of your suggestions. they were greatly appreciated

Bobbon thread is too losse /thread breaks no

Clean out the bobbin area.

Thread the machine with the presser foot up. This opens the tension so the thread can enter. Threading with the foot down closes the tension and the thread cannot enter as it should. When you sew, the top thread is loose and cannot properly connect with the bobbin thread to form a tight stitch. The stitching does not hold and pulls right out.

Thread breakage - top thread? Check the thread spool to be sure there aren't any nicks to catch the thread.

When the thread breaks, check the spool pin to see if the thread is unwinding too fast and wrapping around the pin. Thread nets can help stop this. You can find them at sewing machine dealers.
