Why does the upper thread keep breaking on my Brother Sewing Machine?
- AAmy HurstAug 15, 2025
If the upper thread breaks on your Brother Sewing Machine, several factors could be the cause. First, ensure the machine is threaded correctly, paying attention to the spool installation, spool cap, and needle bar thread guide. Remove any knots or tangles in the thread. The thread might be too thick for the needle, so check the fabric, thread, and needle combination table. Also, the upper thread tension might be too strong and require adjustment. A bent or blunt needle should be replaced, and an incorrectly installed needle should be reinstalled properly. Finally, scratches on the needle plate, presser foot, or race (bobbin case) may require replacement or consultation with an authorized dealer.
