Upper thread keep breaking

Have you tried loosening the upper tension? Remove the upper thread, RAISE the presser foot and rethread from the beginning (make sure it follows the correct thread pathway). Sometimes the upper thread jumps out of a thread guide or wraps around something. Or try a different brand of thread? Avoid old or bargain bin threads--use good quality thread. Could also be the incorrect needle for the thread/fabric, ie thread too large for the needle eye.

Why Does My Thread Keep Breaking While Sew

...

Is your thread new? sometimes if it's older thread it will break often, finally changed my thread and it worked fine.

Check your tension, especially the tension disks for loose thread. Then rethread the whole thing.

Check the spindle the thread is mounted on and see if it\'s wrapped around it. Sometimes thread will catch and wrap around the spool spindle and break.

Check thread guides to be sure there are no nicks that might be catching the thread or damaging it.



Replace the needle.. a burr in the eye can cause upper thread to break. Needles should be replaced often, modern fibres can be hard on them, they get dull and that\'s no help for anything either.



Make sure the thread spool is mounted on the spindle with the thread coming off as directed in the manual. Some machines only work when the thread feeds in the right direction from the spool.



It can also be a tension issue.. tight upper tension or tight bobbin tension. Bobbin tension may be adjustable manually, but it\'s pretty rare for it be a problem. Upper tension, I don\'t know. I\'ve yet to get into computer machines so am not familiar with how they set upper tension.



But the mechanism that produces the tension can wear out or break and need replacement.

No oiling by the user.

Computerized machines are lubricated and sealed in the factory.

If you are the original owner, you could invalidate your warranty if you go beyond the maintenance routine described in the manual.

To keep the warranty, your machine is to be serviced by an authorized Brother tech on a regular basis - once a year if it gets heavy use.

General maintenance, per the manual, will keep the machine in good working condition.

you need to change your needle first. then if that does not work you may have a small area on your bobbin case that has been damaged

Two reels of thread on the top,make sure the threads go seperate sides in between the tension discs, thread both needles but remember not to put the stitch width more than 2.

OK. I was just being kind of an idiot. I replaced the bobbin spool with one that came with it and it's working fine now. Apparently this machine is very picky about the type of bobbin you use.

I had the same problem with the blue thread- it would sew and inch then pop- mine worked wihtout breaking after I re threaded in this order: green, blue, red then yellow
