Sewing Machine: Needle won't move
A disengaged clutch, broken drive belt or internal drive gear failure can prevent the needle from moving.
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. You'll typically need to have a service technician examine the sewing machine and fix a drive gear failure.
Replace the sewing machine drive belt
The drive belt transfers motor rotation to the hand wheel and upper shaft. If the belt breaks, the hand wheel won't move and the bobbin-winding spindle won't spin. Examine the drive belt and replace it if it's worn or broken.
