What to do if my Brother Sewing Machine is skipping stitches?
- B
  Brett RobersonJul 31, 2025
  If your Brother Sewing Machine is skipping stitches, make sure the needle is correctly installed. If the needle is properly installed, but the issue persists, consider that the looper points may be dull and need replacement. If the loopers are ok, the needle and looper timing, or the clearance between them, might be incorrect and need adjustment. Also, verify and adjust the lower thread take-up timing if necessary.

How to fix a Brother DA-9280 Sewing Machine that does not feed work?
- A
  Alison SmithAug 5, 2025
  If your Brother Sewing Machine isn't feeding the work, the feed dog might be too low, or the presser foot pressure might be too small. Try adjusting the feed dog height and the presser foot pressure. If the problem persists, a serviceman should check if the feed dog is worn out, or if the presser foot floats and does not fully press the work, or if the feed dog and presser foot work on one side only.

Why is the upper thread not tight on my Brother Sewing Machine?
- J
  Jonathan HoffmanAug 12, 2025
  If the upper thread on your Brother Sewing Machine isn't tight enough, it could be due to several reasons. Check if the upper thread tension is too weak or the lower thread tension is too strong, and adjust accordingly. Also, make sure that the upper thread take-up thread guide and the thread release lever are positioned correctly. If not, adjust them. Finally, verify the tension plate clearance of the upper thread nipper and adjust it if it's incorrect.
