Question about Kenmore Sewing Machines

1 Answer

My Kenmore usually works great but lately the top and bottom threads aren't interlocking so they loop on the underside of the fabric and just pull out. What might be going wrong? I've made sure the thread and needle size are correct for the fabric; I've thoroughly cleaned and oiled the machine. I just can't figure it out.

Usually, it is in the threading of your machine, read your manual and totally rethread your machine with fresh thread, new needle

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.

Why won't my Elna SU model 62c feed fabric through?


Firstly check that you have the top thread going through the tension device and threaded correctly, including the thread take up lever, loops on the underside is a sure sign that the top thread is not under tension. With the broken needles thrown in, it does sound like your machine needs some love from a trained Elna technician. Great machine so worth the cost of a service IMHO.

I have a Kenmore sewing machine - 12 stitch model which I bought in the 70's. I am having a tension problem and can't seem to fix it. What is the normal setting for the top, and bottom?


Hello

Load your Kenmore sewing machine with the right thread and bobbin thread for your project. If you use the wrong weight thread for your fabric or severely uneven weights of thread, this can cause the appearance of a tension problem when it is, in fact, a thread weight problem or a problem with your sewing speed. If you go too fast, you will break the thread. If you go too slow, you can cause loops. Uneven pressure can cause stitches to vary greatly.

Test your Kenmore sewing machine's tension by sewing on a piece of scrap fabric. If your tension is way off, then test on some basic cotton or a firm blend simply to get your tension right. Do not try to start adjusting your tension on silk or leather. Get a base adjustment on a more standard fabric first.

Look at the top threads and bottoms threads. If the tension is off on one side, it will usually affect the other side slightly. So select the side that looks more maladjusted to start adjusting the tension.

If the top thread is too loose or too tight, you will need to adjust the tension dial. This dial is usually located a few inches above the needle on the Kenmore machine body. Usually, your machine will have markings to indicate which direction tightens the tension. If these have worn off over the years, watch the dial as you turn it. If it appears to move toward the machine body, then it is tightening.

If the bottom thread is too loose or too tight, then you will need to open the door to the bobbin case. On some Kenmore models, there is a little screw near the bobbin case that can be adjusted slightly to adjust the tension. On other Kenmore models, there is a screw on the bobbin case itself--not on the bobbin, but on the bobbin's casing. This will also adjust the bottom thread tension. Adjust the bobbin thread tension to make slight changes.

If the thread is looping severely on one side, the thread weights might be off. For instance, look to see if you have a lightweight thread on the bobbin and a heavyweight one on the top. If the thread keeps breaking, the top tension or bottom tension could be too tight or the thread is too lightweight for the material you have selected. Check your combination of threads and material. Also make sure you are using the right weight needle and the right foot for the sewing step or project you are working on.

If your Kenmore sewing machine's tension is off severely or if you have not used your Kenmore in a long time, then you might need to take your machine in to be serviced. Sometimes, the inner parts need to be oiled or the entire machine might need to be cleaned and calibrated by a professional. If you sew a great deal or if your machine sits idle a lot, both situations will usually require some servicing to keep your Kenmore sewing machine and its tension in perfect working condition.

The top stitch is perfect but underneath the material there are many loops. I am assuming this is from the bobbin. How do I correct this?


no, more likely your top tension is too loose causing the loops on the underside of your fabric, loops on top would be bobbin too loose. raise presser foot and rethread top thdead pulling thread into tension fully. set top tension dial to 5 and test sew. if still looping underneath try tightening top tension by turning dial up to 6. but usually top tension should only need minor adjustment tweeks. you can test top tension by lowering pressure foot to engage tension and holding thread just above needle thread guide, pulling thread downwards . there should be resistence on it to your pull. if you cant feel any then tension device may be faulty, and require service.

Thread is botching up on the bottom. kenmore 17828490


Check the top tension dial is set to the middle setting of 5 or so and also check if the thread is actually between the tension discs and under tension. Lower the pressure foot, then pull the top thread just before it gets to the needle, it should be very firm. If not, then raise the pressure foot, pull the thread out and rethread the top thread, pulling it firmly between the tension discs.

Loops on the underside is usually top tension issues and visa versa if you get loops on top, check the bobbin thread tension.

Hi, What steps do I need to take to correct loops on the underside of the fabric. I have changed the needle, re-threaded the machine, switched the bobbin


Looping on the underside is usually your top thread coming through as its not under tension correctly. So rethread the top of the machine carefully, checking your threading diagram in the manual and checking the thread is going between the tension discs carefully.

You also should clean between the tension discs regularly as thread sheds dye particles and fine fibres and this will build up with time. Turn tension dial to zero, then carefully slide in the selvage edge of a piece of waste cotton and slide it back and forwards between the discs carefully to remove any buildup.

Now turn tension dial back to the medium number, usually 4 or 5 is the recommended setting, and rethread top and bottom as per your manual threading diagram, and try again.

There is good general machine maintenance and threading information at www.sewing.about.com, however if the above fails to improve the situation, then perhaps the top tension device has failed and needs replacing.

I think the bobbin tension is off - I have large thread loops on the underside of the fabric when I sew


It sounds crazy but if you have loops on the underside of your fabric it means your upper thread is not properly threaded (and vice versa for loops on the top of your fabric). So re-thread your top thread, change to a new needle if you've been sewing with it for a months and you should be good to go. Let me know if you need any more help.

Singer 301a...sews on top of fabric nicely...bottom is just loose loops of thread...it's like the bobbin is not sewing...I put 2 different colors in to see...top is perfect...on bottom of fabric I see the...


This is a tension adjustment problem. It's good to use two different colors of thread, like you did. From your description, the top thread (needle thread) tension needs to be tighter. As you tighten the tension of the top thread, you'll see that the top thread pulls the bobbin thread up into the fabric so it's no longer laying loose on the bottom of the fabric.

You'll need to have the pressure foot down when you tighten the tension. Tighten it a little, sew a practice seam, check to see what the stitch looks like. Tighten it a little more, sew, check, etc etc--until both top and bottom look the same--you shouldn't see much (if any) of the bobbin thread color on top of the fabric or the top thread color on the underside.

Let me know how this works for you, ok?

No bobbin tension


If the thread is loose on the bottom of the fabric, it's actually the top thread is too loose. Think of 2 little elves playing tug of war in your machine, one on toip and one underneath. If you have loops on bottom, the top needs to pull harder (tighten top tension)
