Why is my Brother BE-438HS upper thread breaking?
- J
  Joshua KellyAug 20, 2025
  The upper thread may break due to several reasons: * The upper thread tension might be too strong - adjust it. * The needle may be installed incorrectly - install it correctly. * The thread might be too thick for the needle - use the correct thread. * The thread take-up spring tension and height may be incorrect - adjust them. * The shuttle hook, needle hole plate, or needle may be damaged - file smooth or replace the part. * The thread may be melting (if it is synthetic) - use the needle cooler.
