    • B
      Brian McfarlandAug 16, 2025
      Your Brother sewing machine might not be working due to a few reasons: it might not be plugged in, so ensure it is properly connected to a power source. The main power switch might be off, so turn it on. Also, check if the bobbin winder shaft is pushed to the right; if so, move it to the left. Finally, make sure you are using the foot controller correctly.

      Skipped stitches on your Brother sewing machine can occur if the upper thread was not threaded properly, so correct the upper threading. Ensure you are using the right combination of fabric, thread, and needle. Replace the needle if it is bent or blunt. Make sure the needle is inserted properly. Also, if dust has accumulated under the needle plate or in the shuttle race, remove the needle plate cover and clean the plate and the shuttle race.

    Why does the upper thread break on Brother lx3125 Sewing Machine?
    • A
      Amanda WagnerAug 27, 2025
      The upper thread on your Brother sewing machine may be breaking because it was not threaded properly, for example, you have not fitted the spool properly, or the thread has come out of the guide above the needle. Make sure to correct the upper threading. Also, check for and remove any knots or tangles in the thread. Ensure the needle is appropriate for the thread you are using. Loosen the upper thread tension if it is too tight. If the thread is tangled, for example, in the shuttle race, remove the tangle thread and clean the shuttle race.

    Why Brother Sewing Machine thread tension is incorrect?
    • W
      Wendy BradleyAug 30, 2025
      Incorrect thread tension on your Brother sewing machine can be due to several factors: the upper thread may not be threaded properly, so correct the upper threading. The bobbin thread may not be wound properly, so wind the bobbin thread properly. You may not be using the right combination of fabric, thread, and needle, so choose a thread and needle that are appropriate for the type of fabric. The presser-foot holder may not be attached properly, so attach it correctly. The thread tension itself may be incorrect, so adjust the tension of the upper thread. Also, make sure you are using a bobbin that has been designed for this machine, and that the bobbin is set correctly.

      If the lower thread on your Brother sewing machine is tangling or breaking, it might be because the bobbin thread was not wound properly, so wind the bobbin thread properly. Replace the bobbin if it is scratched or does not turn smoothly. Remove any tangled thread and clean the shuttle race. Ensure you are using a bobbin that has been designed for this machine. Also, make sure the bobbin is set correctly.

    Why Brother Sewing Machine makes a high-pitched noise?
    • D
      Dr. Dustin CoxSep 4, 2025
      A high-pitched noise while sewing with your Brother sewing machine may be due to dust buildup in the feed dogs or shuttle race, so clean the shuttle race. Also, ensure the upper thread is threaded properly. If the bobbin case is scratched, replace it. Use only bobbins designed for this machine. Insufficient oiling can also cause this, so oil the machine weekly if used more than an hour daily, or daily if used more often.

      Joseph HughesSep 7, 2025
      If the stitch is not sewn correctly on your Brother sewing machine, it may be because the presser foot you are using is not correct for the type of stitch, so attach the presser foot that is correct for the type of stitch that you want to sew. The thread tension may be incorrect, so adjust the tension of the upper thread. Also, the thread may be tangled, for example, in the shuttle race, so remove the tangle thread and clean the shuttle race if necessary.

    How to fix fabric wrinkling with Brother lx3125?
    • H
      Heather FergusonSep 10, 2025
      If the fabric is wrinkling while using your Brother sewing machine, it could be because the upper thread was not threaded properly, or the bobbin was not fitted properly, so thread the upper thread and wind the bobbin thread properly. Ensure the spool is fitted properly. Check that you are using the right combination of fabric, thread, and needle. Replace the needle if it is bent or blunt. If you are sewing thin fabric and the stitch is too thick, sew with stabilizer material under the fabric. Adjust the tension of the upper thread if it is incorrect.
