The top tread always breaks or slips out of the needle why I'm sewing. It's like the tension is too high, but nothing changes when I adjust the tension.

Did you thread it when the pressure foot was up? It must always be threaded with the pressure foot up as this disengages all the tensions. Also try re-threading as sometimes the thread misses a tension disc. If the bobbin is threaded wrongly it can also cause thread pulling. If the thread is poor quality it may have knots that cause this problem.

I would suggest removing all threads and cleaning between any visible tension discs incase there is a piece of broken thread stuck in there, then re-thread the whole machine with pressure foot up.

Thread keeps breaking don' know how to adjusT tension


Since we don't know what machine you have, we're really limited on suggestions. The owner's manual should have instructions for tension setting. If you don't have a manual, search for:
Make Model manual

Assuming it is the top thread that is breaking. Breaking thread usually indicates either the machine is misthreaded or the tension is set too high. However, there are other symptoms that indicate other issues, ie if the thread is shredding or fraying, possibly the incorrect needle is being used or there is a snag/burr somewhere in the thread path. If the machine sews for approximately 2 inches and then breaks, something is catching the thread causing it to stretch until it breaks. Frequently, my thread slips off the thread spool and wraps around the spool pin and breaks.

AVOID old or bargain bin thread.

Remove the top thread from the machine.
Install a brand new needle.
ALWAYS RAISE the presser foot and rethread from the beginning.
Verify the thread path is correct.
Set the top tension to the midway point and retest the machine.

My serger won't make the chain stitch. I have carefully re-threaded it about 5 times, but no change. I haven't changed the needle recently either.


What exactly is happening? Is it breaking thread? Is there any thread that is not feeding? Need more specifics.

Here are general instructions for when issues arise:

Change the needles if they are not new. Make sure they are inserted properly and all the way up in the needle clamp.

RAISE the presser foot, clip all the threads below the thread tree, and remove all threads from the machine by pulling on the thread tails. (Always remove thread by pulling down, never up.)

Rethread from the beginning insuring that each thread is treaded in the correct order (consult the manual). ALWAYS rethread with the presser foot up! (NOTE: on most machines, it is the upper looper first, lower looper second with the thread tail draped OVER the top of the upper looper, then the two needles.) Grasp each thread above and below the tension disk and give it an extra little tug to make sure it is fully seated in the tension disk.

Adjust the tension dials to the midway point.

Then test.

How do I determine what tension to use?


Tension setting is trial and error. To learn choose two color threads same weight and manufacture. placing one in bobbin other top tread.

Set the lower tension to light. The lower tension has always been lower than the top.

Depending on needle size and material the upper needs to be set.

Use the images as a guide.

I have an husqvarna Viking mega quilter18x8 with the imperial frame. I am having problems with the tension and the tread keeps breakingms with. The tension and the tread keeps breaking. HELP!!


If the thread breaks at the needle and is feeding smoothly from the spool, you may have the tension too high. It is impossible to say what the setting should be because the knob rotates all the way around several times. Loosen it off until you see needle thread pull to the back of the quilt, then tighten until it just balances the interlocking of the stitch in the fabric. Test with little swirls, that's most likely to pull needle thread to back.Also, check that the needle is properly installed and that the hook to needle timing and clearance are good.Nesting of thread underneath usually happens if the foot lifter is left up or the tread is not fully in the disks of the tension unit.

I have a serenade, and problems from the start. It skips stitches, upper thread breaks with all tensions, or just too tight and it doesnt stitch just makes loops and tangles up. A friend of mine has had...


try a new ball poine needle. Sounds like intermittantly not picking up the bottom thread....It doesn't take much to shorten the needle just a hair to cause this, especially with sharps. Try a ball point needle...The last longer and are more durable. I sew everything with a ball point. Top Thread will also break if the top tension is too tight. Remember, when adjusting tensions, baby steps all the way...just a lil' smidgen might be just what you need. Also, always make certain the machine is level so that the settings don't vibrate out of adjustment. Dusty Tread will also brea easy. Keep threads clean and dust free. Good Luck
