Why does my Brother LH4-B814-4 Sewing Machine thread keep breaking?
- JJames RiveraAug 2, 2025
Your Brother Sewing Machine thread may be breaking because of several reasons. It could be due to a blunt or bent needle (replace the needle), a needle that is too thin (use a thicker needle), a damaged needle plate (replace the needle plate), or poor quality thread (use higher quality thread). Also, too much tension on the upper thread (reduce the tension) or improper threading (re-thread the machine correctly) could be the cause. Other potential causes include a damaged hook point (replace the hook), the hook being out of timing (re-time the hook), or dust or lint in the hook (clean the hook).
