Question about Bernina Activa 140

1 Answer

For the last few days my aurora ,430 will go about 20 stitches then stop saying a thread broke. I have changed everything, cleaned everything, turned off and restarted everything, reset everything... you name it. I have a monogramming business and have resorted to sitting by my machine and hitting the start button over and over, which is very time consuming and frustrating. What could be the problem and solution?

Sounds to be that the "check spring" came out if its "flag". Not sure if you want to take it to your repair shop or do it yourself.
Remove side panel/head cover/ end cap.
When threading the machine you thread the check spring when you bring the thread down and up.(sorry I just cant think of a better way to discribe it).
Find the check spring.
There should be a small black plastic part that the check spring is controling, and my guess is that it has came out. This is a comon problem with this machine.
I know this is a horable explanation but this is hard to discribe.
Hope this helps

Makes one stitch then abrupt stop with threads bunching up from bottom


Have you taken the bobbin out and made sure there is nothing caught in the bobbin race area. Maybe even unscrew the plate and take the whole bobbin race assembly apart and clean well. Once that is done put back together then re thread machine. Next I would start by hand turning the machine and doing some stitches slowly with the fly wheel make sure to to forwards only never turn the fly wheel back wards. If everything seems clear give it some power slowly and see how it goes.

Make sure you are threading the machine correctly. Make sure you are using serger thread that isn't old. Make sure you are undoing all the threads when it breaks and thread it from the beginning.

Make sure you have the right needles in their respective places. My Juki MO has two different size needles.

Machine stops and says thread is broke. Mean while the thread is not broke


Probably one of two issues. There is a sensor in the upper tension that is operated by the check spring assembly. If its broken, twisted or jammed it will sew a few stitches, maybe more and then beep and stop. A service man is the only fix, sorry.

Trouble with sensor


The upper thread sensor on most Brother's is activated by the check spring. Either your check spring has broken or is stuck. You may be able to fix this if you can get to it. A drop of oil may be all you need. I may be able to give more specific advise if you tell me what model it is.

Good luck!

Skipped stitches


You will need to take your machine to a dealer and have it adjusted. Machines should be cleaned and serviced at least once a year. Needles should be replaced when dull. Skipping stitches can also be from using the wrong kind of needle. When quilting on cotton, use sharp needles, when sewing on knits use a ball needle. You can use a universal needle but they aren't perfect and will cause skipping on some fabrics.

Hi Sally,
Don't forget to change your needle too. It may not look bent, but it probably is.
