Lower right thread keeps breaking

The lower right thread keeps breaking when I begin to sew. I think I'm not threading the machine properly - but I appear to be following the same instructions as the DVD! Thanks Karenxxx

Re: Lower right thread keeps breaking

I've had this too, but thanks to info on a different board, I've solved it!! Take a deep need to rethread the entire machine in order. So cut all the threads and go back to the top, begin at the right hand side, with the lower looper thread, following the dvd instructions. Then the upper looper and finally the two needles. As you're rethreading, make sure you pull the threads out to the back of the machine so they don't get tangled. That should see you back and sewing in no time!

Hope it works for you.

Overlocker is not sewing. How can I thread the lower looper without it breaking?

Thread breakage is usually an indication that the machine is not threaded correctly or the tension is set too tight.

As a reminder, if a thread breaks, save yourself some (lots!) frustration and rethread every thread From The Beginning. Rethreading only the broken thread will usually just lead to it breaking again. Sergers are finicky and must be threaded in the correct order. Also, Always raise the presser foot while threading. Your thread breakage is occurring with the lower looper. Be sure that you are threading every guide and give it a little tug going through the tension disk. Usually, the last step is to drape the lower looper thread over the top of the upper looper before it is pulled back and under the presser foot. Be sure to initially set the tension at the midway point between the high & low numbers.

Just bought Juki MO1000. Have threaded and re-threaded several times (easy enough) because the lower looper thread (position 1) thread breaks after sewing 4-5 inches. Any ideas?

Yep, 9 times out of 10 when thread breaks, something is not threaded correctly. Also, whenever thread breaks or becomes unthreaded, best policy is to unthread everything and start over from the beginning. Simply re-threading the broken thread will usually not work.

Remove all the thread from the machine. RAISE the presser foot (important to ALWAYS do this so the threads will seat properly in the tension disks).

Rethread totally from the beginning making sure to follow the threading instructions for each thread and that the threads are threaded in the ORDER (ie upper looper, then lower looper, then needles) per the manual. If the threads are not threaded in proper order, the machine will most likely never work.

When threading the lower looper, as the last step, be sure to pull the thread tail over the top of the upper looper mechanism before pulling the thread tails under the presser foot.

If the thread continues to break, make sure the tension for that disk is not set too tight. Loosen it up and see if that makes a difference. Most factory standard thread tensions are around the midway point between the high and low numbers. Then slight adjustments can be made from that setting to tweak the tension result.

Why does lower looper thread keep breaking?

Usually, thread breakage is due to incorrect threading. When a thread breaks or becomes unthreaded, the best policy is to remove all the thread and rethread from the beginning. Be sure to RAISE the presser foot before threading to allow the thread to seat properly in the tension disk. Also, be sure to thread each in the order specified in the manual or it is unlikely your machine will ever function properly.

Kenmore 385 #3 thread breaks

Try removing thread #3 from the tension altogether. If this doesn't work, then try using a different spool of thread. Some break easier than others. If this doesn't work, try rethreading your serger from the the beginning. Upper looper first, then lower looper, then needle. Test on scraps.

Thread keeps breaking and underneath not sewing right

There may be a broken thread in the bobbin case effecting the lower thread tension. clean all parts and determine if the upper thread or lower thread is breaking if cleaning does not help. double check your machine threading and bobbin installation direction. : this site has many operator manuals if the above suggestion does not help.

The lower looper keeps breaking thread

Hi,...if the lower looper thread is breaking before you sew six inches or more then I suspect a threading problem.When the lower looper thread breaks, You MUST unthread the needles before you thread the lower looper. Thread the looper and then rethread the needles.

Hope that helps,

Lower looper

It is impossible for a looper to come unthreaded if you are holding one end and the other is still feeding off the spool. Somewhere a thread broke - must be either the upper looper or the needle. Try completely re-threading your machine. Many machines have an "order" they prefer to be threaded. Try starting from the right tension guide and work to the left.
