Why does my Brother Sewing Machine upper thread keep breaking?
- K
  Kelly HansenAug 16, 2025
  Upper thread breakage in your Brother Sewing Machine can occur due to several reasons. It may be caused by incorrect needle installation; ensure the needle groove faces forward and the needle shank touches the top edge of the needle hole of the needle bar, and consider replacing the needle. Incorrect threading of the upper or lower thread can also cause this issue, so ensure both are threaded correctly. A rough thread path, especially around the needle plate hole, can also lead to breakage; polish or replace the affected part. Finally, improper thread tension or thread take-up spring tension may be the cause; adjust the upper thread tension appropriately and loosen the thread take-up spring tension or lower its height to avoid double hooking.

  If your Brother Sewing Machine is skipping stitches, it could be due to the needle or the thread take-up spring. Check that the needle is correctly installed with the groove facing forward and the shank touching the top edge of the needle hole on the needle bar; consider replacing the needle. Also, the thread take-up spring tension might be too tight; try loosening the tension or lowering the height to prevent double hooking. Adjust it while checking bar tacking stitches.

Why Brother HE-800C seams are uneven at the sewing start?

  Rodney DodsonAug 22, 2025
  Uneven seams at the start when using your Brother Sewing Machine can stem from the upper thread trimmer or lower thread issues. Adjust the upper thread trimmer installation height and ensure appropriate opening timing, and apply grease to the inclined face of the opening cam. Also, check the lower thread tension and add tension to the bobbin holder spring to prevent bobbin slip.

Why seam lifts up at the sewing start on my Brother HE-800C Sewing Machine?
- C
  Casey MorrisonAug 28, 2025
  If the seam lifts up at the sewing start on your Brother Sewing Machine, it may be due to the upper thread trimmer or upper thread feeding. Adjust the timing so that the upper thread trimmer gradually starts opening when the feed mechanism moves about 1.5 - 2.5 mm, and apply grease to the inclined face of the opening cam. Also, loosen the screw to decrease thread take-up amount so that the upper thread does not pull out of the trimmer assembly at the sewing start.

  If the cutter and upper thread trimmer are touching on your Brother Sewing Machine, adjust the cam position. If the feed mechanism operates when the cam has not opened the stop plate, the cutter will bump against the upper thread trimmer.
