Why is my fabric not moving on my sewing machine?
The Thread Tension Is Too Tight When your thread tension is too tight, it can’t move easily through the sewing machine, and the fabric won’t feed properly. Loosening the upper thread tension should enable it to move freely.
What causes a sewing machine to lock up?
Dirt and dust, as well as lint inside the machine, leads to freezing. Sometimes issues with bobbin and hook assembly can also cause freezing of the sewing machine. Once the machine is frozen, you will not be able to move the handwheel and continue with the sewing.
Why is my thread bunching underneath?
A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.
How do you fix the top tension on a sewing machine?
To make a temporary tension adjustment, select the threads for the needle and bobbin, then fill the bobbin and thread the machine. Make a test seam on the fabric that you plan to sew, examine the stitches, then see if you can find a balance using the upper-tension assembly alone.
How do you fix bobbin tension?
To tighten your bobbin tension, turn the tiny screw on the bobbin case a smidgen clockwise. To loosen bobbin tension, turn the screw counterclockwise. A quarter turn or less is a good place to start.

What should the tension be on a Brother sewing machine?
4.0The normal tension setting is 4.0. The upper thread and the bobbin thread should cross near the center of the fabric. Only the upper thread should be visible from the right side of the fabric, and the bobbin thread should be visible from the wrong side of the fabric.
How do you unjam a sewing machine?
Raise the needle to the highest position using the hand wheel. If the needle will not move, gently work the hand wheel back and forth a little bit to see if the needle loosens. If it just won’t move, don’t worry; move on to Step 4.
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.
What tension should my sewing machine be on?
4.5So 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. This should be suitable for most fabrics.
