Why does the needle thread keep breaking on my Silver 392 Sewing Machine?
The needle thread may break due to several reasons: * Improper threading of the needle thread. * Excessive needle thread tension. * A bent or blunt needle. * Incorrect needle insertion. * Failure to draw the fabric to the back after sewing. * Using thread that is too heavy or too fine for the needle.
