Why is my needle not moving up and down?
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 does my sewing machine motor run but nothing moves?
You may need to tighten the inner portion of the wheel on the right side of your machine (hand clutch.) It could also be a broken drive belt. Sounds like you may have a thread jam or lint jam. Check the bobbin winder to be sure it is off.
How do you fix a needle that doesn’t move?
Follow the steps below if the needle bar does not move up or down.

- – Check the position switch to raise the feed dogs.
- Your stitch length may be set on 0.
- – Lengthen the stitch length on your machine.
- Make sure you have the correct pressure foot on the machine.
- Your thread may be tangled.
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.
