Re: Top thread keeps breaking. Is it suppose to be...
Check to make sure you raise the presser foot before passing the thread through the tensioner. If you have threaded it properly, the upper tension may be too tight. Try setting the top tension guide in the middle (4) and test, readjust, test, readjust. Usually, right is tighter (bigger number), left is looser (lower number). The top and bottom threads should meet in the middle of the fabric.
Be sure to read pages 16, 22, and 55 of your manual to troubleshoot your thread breakage problem.

Install a brand new needle (make sure it is compatible with the thread and fabric). Remove the top thread from the machine. ALWAYS RAISE the presser foot and rethread from the beginning. Verify the thread path is correct. Set the top tension to the midway point and retest your machine. Tweak the top tension until the top and bobbin threads meet in the middle of the fabric.
check the age of the cotton
cotton is not a single thread but a series of fine threads bonded with a glue
old cotton glue breaks down and the thread separates easilty
next check that the needle is installed correctly with the grove ( thread groove away from the bobbin hook
check the needle and hook timing because if it is off a fraction , the hook will pierce the the thread causing it to break
next check that the eye is the correct size for the thread in use
a needle eye too small for the thread thickness will jam the thread ans not let slide through the eye properly
If the top thread sews a few inches and then breaks, something is catching the top thread and holding it until it breaks. Usually, this will happen when using the old style thread cones with the slit in the edge to keep the thread from raveling off the spool. To prevent the thread from hanging up, turn the thread spool over so the slit is at the top instead of the bottom. Sometimes top thread breaks will happen if the thread becomes looped around the thread spool pin.
Remove the thread, ALWAYS RAISE the presser foot and then rethread the upper thread. Verify that the thread path is correct and that the thread has not looped around a guide.
If the thread is fraying at the needle eye, the needle/thread are not compatible. Also, the tension may be too high.
Check that the upper tension disk is clean--no gunk buildup or thread pieces stuck.
If the thread is actually breaking when it penetrates the needle plate hole, there may be a burr or nick somewhere below that is catching the upper thread. You can wrap your finger with a piece of fine fabric, like an old pair of hosier, fine knit fabric, etc. and running your finger around in the bobbin area, under the needle plate. If you get snags, then you have a burr or nick. If it is small, you can sometimes smooth it with a fine emery board. If it is a large burr, you may need to purchase a replacement part.
possibly the top thread is being restricted in movement
check that the thread is between the tension plates and not behind it or knotted up in the way it is threaded
pull on the needle thread and it should move with a steady pull not very hard
if it is not moving fairly easily the check how you have the thread installed
also old thread will break easily as the bonding used to keep the strands together breaks down and is difficult for the thread to slide though the needle
another point is the needle to hook timing and the clearance there as well .
if there is a problem there , the hook will split the thread from the needle and break it
if you still have problems , take it to a sewing machine service center ( any one ) and they will advise of the problem and show you how to fix it

1.the needle is damaged
2.the needle is not correctly inserted
3.wrong size needle for the fabric
4.the wrong foot is attached
5.the needle clamp screw is loose
6. Top tension is too tight
7. Machine could be out of time
The needle thread breaks
1. the needle thread is not threaded properly
2. The needle thread tension is to tight
3. The needle is bent or blunt
4. The needle is incorrectly inserted
5. The needle thread & the bobbin thread are not set under the presser foot when starting to sew
6. the threads were not drawn to the rear after sewing
