Why Does The Thread Keep Breaking On My Juki Sewing Machine?
Machine needs maintenance
Make sure that you read your Juki sewing machine manual for the recommended maintenance practices. If the machine is full of debris, it can get damaged, which in turn can also break the thread. It might also slip off easily or develop knots.
Timing or tension is incorrect
If the timing is off, the needle won’t get in the correct position. Therefore, you must know how to properly time the hook and needle as per the Juki model’s instructions. Furthermore, always test your stitches to understand the adjustments you’ll need for the tension to avoid thread breakage.
Needle is damaged
Learn how to replace the sewing machine needle when necessary. If it’s the wrong one or if it is damaged, then the thread can get cut. You should also only use sharp needles, so read this tutorial on how to sharpen sewing needles.
Wrong presser foot or throat plate
Check if the hole on the presser foot is correct to keep the needle from deflecting. You also want the throat plate hole to be correct, or the machine can develop feeding issues. All of which can affect the thread and potentially damage it.
