Why is the upper thread breaking on my Brother BAS-326H-484 Sewing Machine?

If your Brother Sewing Machine's upper thread is breaking, several factors could be at play. Make sure you're using a thread appropriate for the needle. Ensure the needle is correctly installed and the thread is properly threaded. Check for damage on parts like the rotary hook or needle hole plate, repairing or replacing them as needed. Also, verify that the needle and rotary hook timing are correct, and that the upper thread and thread take-up spring tensions aren't too strong. If heat is causing the breaks, consider using a needle cooler or reducing the sewing speed.
