  The upper thread may break on your Singer Sewing Machine for several reasons. It could be that the machine isn't threaded correctly, so rethread it. The thread tension might be too tight; reduce it. A too-thick thread for the needle, so select a larger needle. The needle might be incorrectly inserted; reinsert it with the flat side towards the back. Also, check if the thread is wound around the spool holder pin; if so, remove the reel and wind the thread onto it. Finally, the needle might be damaged, so replace it.
