Question about Sewing Machines

1 Answer

I have an older kenmore sewing machine, the upper thread tensioner doesn't seem to work. I've rethreaded multiple times to no avail. Big loops on the bottom of the fabric. If I open the top is there something to lubricate- that would help?

Read your owners manual, if you do not have one try tias.com and buy one for $10-15. It will be worth it, because you do not have it threaded right.

My pfaff 1475 CD thread is loopy on bottom and breaks on top.


Look very closely at your sample stitching and determine which thread (top or bobbin) is looping and which is breaking. That will narrow down where the problem exists.

A top thread that loops and makes thread "barfs" under the fabric is generally an upper thread tension problem.
Try: Remove the top thread. ALWAYS RAISE the presser foot and rethread from the beginning. Set the upper tension to the midway point (probably will need to tweak this tension depending on your machine).

Stiches at the bottom come out like a rats nest not sewing right?


Generally, thread issues that appear under the fabric are the result of an upper thread problem. What you describe sounds like bird nesting or thread nesting and are usually a result of: mis-threading, thread not being fully seated in the tension disk, and/or upper tension too loose.

Remove the upper thread. ALWAYS raise the presser foot. Rethread from the beginning. Verify the thread path is correct. Set the upper tension to the midway point between high & low numbers (although this will probably need to be tweaked for your particular machine). Retest your machine. Adjust the upper tension until both threads meet in the middle of your fabric.

FWIW, mis-threading may not be your mistake. I have an older machine that the take-up lever is open at the top. Sometimes, usually when sewing fast, the thread will literally "jump" out of that take-up lever and...instant thread mess... So, if this sort of thing occurs frequently with your machine, try to narrow where the problem originates. With my machine, I "manufactured" a method of closing the opening in the take-up lever. Voila! No more jumping thread!

My kenmore model385.16221300 the thread keeps braking and the underside has big loops of thread


What you have is bird nesting or thread nesting and could be a result of several things. Usually, it is because the machine is mis-threaded, the thread is not seated in the tension disk, and/or the upper tension is too loose.

Remove the upper thread. ALWAYS raise the presser foot and rethread from the beginning. Verify the thread path is correct. Set the upper tension at the midway point between high & low number. Retest your machine.

You may need to tweak the upper tension to get it where it should be as all machines differ. The tension is correct when the upper and bobbin threads meet in the middle of the fabric.

I have a janome 8200, when sewing the top stitch is perfect but top thread bunch under neath and no bobbin thread appears to be used, I have changed threads, bobbins and needle,


Be sure to use a brand new needle.

Remove the thread from the machine. ALWAYS RAISE the presser foot and rethread the upper thread. This allows the tension disk to release so the thread will seat properly. Verify that the thread path is correct.

Check that the bobbin is installed correctly (turning the proper direction in the bobbin case) and the bobbin case tension is threaded correctly.

Set the upper tension to the midway point. (This is the beginning point and may need tweaking later.)

Pull the bobbin thread to the top of the sewing project.
How and Why to Bring up the Bobbin Thread P.S.--this works with regular sewing, not just for quilting.

Lower the presser foot and test your machine. Begin sewing slowly.

If there are still issues--upper thread looping, try tightening but if it doesn't improve, the tension mechanism may not be working properly. Check and remove any thread pieces or gunk stuck in the tension mechanism. If still not working, it probably needs service.

If the bobbin thread is still not connecting with the upper thread, the sewing machine's timing is most likely off. (Search the internet for "sewing machine timing." There are multiple web sites and videos available that discuss this OR take it for service.)

My singer sewing machine 7102 is looping the top thread underneath


Upper thread looping under the fabric is usually a sign that the thread is not seated in the tension disk or it is threaded incorrectly. FIRST, make sure you have a brand new needle in it. Remove the upper thread completely. RAISE the presser foot and rethread from the beginning. Verify that the thread pathway is correct. Also check that the upper tension is not set too loose.

Lower thread too loose


Big loops on the bottom of the fabric is NOT the lower thread. First make sure that your upper thread is correctly threaded with the presser foot in the UP position. Do a test seem. If you still have loops tighten the UPPER tension knob. Do a test seem.

If after several upper tension changes do nothing. Remove the upper thread and take some rather rough sturdy fabric like light weight denim and "floss" where the tension discs are then rethread... and try again.

New Home ss2015 machine. I am having trouble with the thread tension. I have loops on the bottom. I have cleaned the bobbin case, changed the needle, re-threaded and moved the upper tension all the way up....


try adjusting the top tension to 3 & if it doesn't stop the looping, try 4 but I wouldn't go any higher than 5,, if changing the top tension doesn't help then I suggest taking the machine in to have it serviced. the bottom tension is more difficult to do,, it's also very possible that the top tension dial is messed up & needs replacing. only a sewing machine shop can tell for sure.

Kenmore Sewing Machine Drop-in Bobbin Tension Adjusting Problems


looped stitches are usually caused by improper tension. when the loop is on the upper side, it may be corrected by loosening the top tension or by tightening the lower tension (turn the tension screws on the bobbin a hair at a time)

since using the machine only a few times it is best to clean the machine from dust (can use a can of air) blow air into the bobbin area and between the tension disks and under the throat plate.

make sure the machine is threaded correctly and bobbin is evenly threaded

Upper thread tension wire broke off!!!


The part that is broken is called a check spring. It keeps the thread away from the point of the needle until the needle pierces the fabric. You should probably take the machine into a reputable repair shop.

Thread on bottom, bobbin thread loose


Sounds as though you've misthreaded the upper tension. The best way to verify this would be to thread your machine, lower the presser foot on to the material. Now try pulling the thread through the needle. (Assuming your upper tension dial is set to a number greater than one). You should feel resistance. Should you not feel resistance, rethread your upper tension.
