Why does my bobbin keep getting stuck?

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.

How do you fix a sewing machine that will not move?

Engage the hand wheel clutch if you have it disengaged for bobbin winding. If the needle won’t move with the clutch engaged, unplug the sewing machine and check the drive belt. Replace the drive belt if it’s broken. If the drive belt is okay, an internal drive gear failure is likely preventing the needle from moving.

Why is my handwheel stuck?

It takes a lot to overheat the motor on your sewing machine, but newer sewing machines have an automatic shutoff feature to prevent your motor from getting damaged when it gets too hot. If you’ve been sewing fast for a long time, your handwheel might be stuck because your machine is too hot.
