Why does my upper thread keep jamming?
The tension could be too tight or too loose. Set the tension to the basic thread tension setting or adjust the tension manually. The combination of the needle size, thread size and fabric is incorrect. Be sure to use the correct size needle and thread for the type of fabric that you are sewing.
Why does my top thread keep coming unthreaded?
1. The upper thread was not threaded correctly. The spool is not installed correctly, the spool cap is too big for the spool being used, or the thread has come out of the needle bar thread guide.

Why does my thread bunch up?

Why does my sewing machine keep jamming underneath?
However certain you are that the problem with the machine is most likely due to a huge tangled mess of thread in the bobbin underneath the fabric, the most common reason for the jamming is usually the lack of sufficient tension in the upper thread.
What tension should my sewing machine be on?
As the bobbin thread tension is factory-set and wouldn’t usually be adjusted for normal sewing. So we’ll be talking only about the top thread tension since that’s where you’d usually make the adjustments. The dial settings run from 0 to 9, so 4.5 is generally the ‘default’ position for normal straight-stitch sewing.

How do you adjust the tension on a bobbin?

What causes a thread to get stuck in the bobbin?
This can be caused if the top thread tension is too tight, or if the bobbin thread is not in the bobbin case tension. Check that the upper thread is feeding freely without obstruction (like getting stuck behind the spool cap or getting caught on any rough spots o the thread spool itself).

Why is my thread bunching on my sewing machine?

How can I get my thread to turn back?
You want the thread to turn back, then go into the slit. Usually, with oscillating or rotary hook systems, when you put your bobbin in the bobbin case and pull the thread, it should rotate clock-wise. Drop-in bobbins will usually rotate counter-clock-wise.
