The needles on my Janome 9102D keep breaking

I had a problem with the overlocker just not doing anything right. I took it for service and then the thread in the bottom looper keep breaking free. That seemed to pretty well cure itself and in it's place the right hand needle kept breaking. It seems to be coming down in front of the upper looper rather than behind which then drives it into the presser foot. Then last night the left hand needle started to break or bend. I am careful to ensure they are seated properly but having replaced a dozen needles yesterday I am at my wits end.

    The same thing happens to me sometimes. I take a deep breath and keep rethreading and replacing the needle until it works. I usually only have to replace a needle once and rethread it a million times, happens to me if the fabric is really thick, like denim. I've never taken it in, so I don't know what the real solution is, sorry.

I had a similar problem with my machine. What I've started doing with mine is setting the stitch length at 3 and the differential feed ratio at 1.0 then I set all 4 thread tensions at 3. I thread the machine from right to left, and then when everything seems to be working okay I take scrap material to test the tension and then set them to suit the material I'm using. Right now I'm working with a twill so my settings are 4-4-5-5. This seems to have stopped the thread slipping off the bottom looper and I haven't had any more needles break. I hope this is helpful.

Can I just change the needle plate on my janome overlocker been told I need to have loopers reset


Sergers are funny things. You can certainly try just replacing the needle.... make sure you thread correctly. upper looper, lower looper, right needle left needle... etc.

Before you take off sewing... run the machine by hand a few revolutions if it seems to be moving with no more clunking etc. try to sew. If it breaks the needle again. Stop immediately and take it in.

Thread keeps breaking after a while on my overlocker


I would suggest checking the tension, it may be to tight

I would change the needles

I also would rethread the machine to make sure it's threaded right

..the right needle thread keeps coming out and I


Sounds like you have a tension problem. Have you re-threaded? Check tension discs for bits of broken thread which may cause jamming. The thread must be catching somewhere. Pull it through by hand to see if it is too tight.

Light is on but won't sew


Sounds like either the foot control or the motor has failed. The foot control is the easiest to replace, you should be buy a replacement control for about 30.00.

My janome harmony 9102D serger I think is out of


i suggest you get a tech to re-time your machine. timing is complex on an overlocker and if not done correctly you will probably break a looper.
