Thread Break Troubleshooting
Lower thread path and bobbin
Improper Hook Timing.
If thread breaks are occurring frequently on all sewing head’s needles.
Lower Thread Path Problems. Make sure the bobbin is installed properly. Remove any lint or
dirt build-up. Make sure the thread trimmer knife is fully retracted.
Upper thread path and needle
Improper Needle Depth.
This is more likely the cause if thread breaks occur on just some
of the needles.
Defective Needle.
Easy culprit to rule out first. Make sure it’s inserted properly.
Upper Thread Path Problems.
Check the thread path to make sure it is following the correct
path from thread cone to needle.
Incorrect Thread Tensions. If the tension is too tight it could lead to missed stitches and
thread breaks.
Defective Thread. Another simple thing to rule out. First, pull off a few yards to pass a bad
section of thread and if that doesn’t work, try replacing the thread with a new cone.
The garment or fabric
Stiff, Thick Fabric. Needles tend to bend slightly as it passes through causing the thread to
graze against the needle plate resulting in the thread shredding. To fix this problem try a
larger needle.
Hidden Obstructions in the Garment. Check to see if there is any hidden obstructions in the
garment such as bulky seams, inside pockets, hidden buttons.
Fabric and/or Hoop Bouncing During Sewing. Make sure the item is hooped properly.
Loosely hooped fabric will bounce up and down during sewing, known as “flagging”.
The embroidery design
Design Density.
Too high density of thread in the design can cause needle deflection, which
lead to thread shredding and breaks.
Short Stitch Lengths.
Extremely short stitch lengths may cause thread to pile up in one area
known as “nesting”, resulting in thread shredding and breaks.
