  If the upper thread breaks on your Singer Sewing Machine, several factors could be the cause. First, ensure the machine is correctly threaded by rethreading it. Also, check the thread tension; if it's too tight, reduce it. The needle might be too small for the thread, so try a larger needle. Make sure the needle is correctly inserted with the flat side towards the back. Check if the thread is wound around the spool holder pin and rewind it onto the reel if necessary. Finally, a damaged needle can also cause thread breakage, so replace it.
