  Jamie SheaAug 15, 2025
  If your Brother Sewing Machine is skipping stitches, there are several potential causes. First, check if the needle tip is bent or broken and replace the needle if necessary. Ensure the needle is properly installed and the machine is correctly threaded. Adjust the presser foot pressure, as it might be too weak. If the needle is too thin, replace it with a slightly thicker one. Also, verify that the presser foot height is correct and the needle and rotary hook timing are properly set by adjusting the height of the needle bar. Finally, adjust the tension of the thread tension spring if it's too weak.

  Upper and lower threads may break on your Brother Sewing Machine due to several reasons. The needle might be bent or broken, in which case you should replace it. Also, make sure the needle is correctly installed and threaded. The thread tension could be too weak or too strong, so adjust the upper and lower thread tension accordingly. If the thread tension spring operating range is too small, adjust its position. Finally, inspect the rotary hook, feed dog, and other parts for damage; smooth them or replace if needed.

What causes the lower thread to tangle at the start on a Brother Sewing Machine?

  Kelly HuertaAug 30, 2025
  If the lower thread is tangling at the sewing start on your Brother Sewing Machine, ensure the bobbin spins in the opposite direction to the rotary hook when the lower thread is being pulled. The bobbin winding amount should not be more than 80%. Make sure the bobbin tension spring is attached. If the bobbin is not turning smoothly, replace it. Use only bobbins specified by Brother.

Adjust the thread guide if the trailing length of the upper thread is too short after thread trimming. Sharpen or replace the knives if the threads are not being trimmed cleanly.
