I have a LS-2125 brother machine, and when I sew the thread from the bottom catches and breaks. I have taken the bobbin casing apart and cleaned and oiled it, changed bobbins, tried to adjust the tension,and varied the speeds at which i sew and nothing has helped. Any solutions?

How to Thread bobbin on the Brother LS 2125 sewing machine

There may be a broken thread in the bobbin case effecting the lower thread tension. clean all parts and determine if the upper thread or lower thread is breaking if cleaning does not help. double check your machine threading and bobbin installation direction.
http://www.mastersewusa.com : this site has many operator manuals if the above suggestion does not help.

Here are some things that may fix the problem:
1. First, replace the needle
2. Next, remove the thread and completely rethread the machine
3. Remove the bobbin, clean any lint or thread from around the bobbin, and replace it.
Try sewing again on scrap fabric.
I hope this helps.

You need to either adjust the tension or ensure that you have routed the bobbin thread properly.

there is a screw on the side of the bobbin case, which needs to be turned to the left or counter clockwise to loosen the tension and also change the needle because a burr on the end will cause problems with bobbin thread

Hello,
Here are some things to try.

* Re-thread your machine

* Change your bobbin
There could be a nick along the edge of your bobbin spool that’s catching your thread as you
sew.

Also, before you start to sew a seam, grasp the upper and bobbin thread tails. Hold them back
and out of the way as you sew your first couple of stitches. This will keep them from getting
caught in your machine.
I hope one of these solutions help.

Make sure you are threading the machine correctly and it has the proper tension. Also check the bobbin the thread has to go thru the little lash

Try re-threading, make sure the presser lifer is up so the tension discs are open and the thread will go into them. It sounds like you may have missed either the upper tension discs or the take up lever.

A drop of oil on the hook wouldn't hurt if you haven't oiled in awhile.

good luck!

You may be sewing too fast, using cheap thread or your tension is off. All of which can cause your bobbin thread to break.

go back and check to see if the needle is inserted properly. I have had this problem on other machines and have found that this is a cure for some. i just got in a hurry and put it in wrong(most times the flat side of the needle goes towards the back).
