I'm sorry if this response seems rude, but have you double and triple-checked it's threaded correctly? (I missed a step on mine not so very long ago and ended up with the same problem. Very frustrating.) Undo it all and start fresh, using a good quality thread?

It could be the thread. I got a (what I thought was a bargain) lot of thread It was very cheap and was alway breaking, or your top tension is too tight.

I have cleaned and oiled my Brother sewing machine after breaking about 3 needles. But now it seems that the needle thread keeps getting hung up on the bobbin shuttle and breaking. Can anyone please tell me what is causing this problem?

You might take out the bobbin and look under and around it for 'fuzz'. I have to clean out under there pretty often or my thread starts breaking or jamming up into 'birds nests', or sometimes it'll just skip stitches. Try using the cleaning brush that comes with sewing machines, or just use a cheap artist's type brush and really brush it out good, then put a drop of oil in that area also and wipe excess away. I've bought several old sewing machines at yard sales that they said wouldn't sew, and after taking apart and cleaning all under the bobbin area, they sewed just fine. :^)

Sometimes, you even have to take out the parts that hold the bobbin and clean under there, too. Be careful that you remember exactly how you take it out or you might have trouble getting it set back in. Take notes to remind yourself, because if your sewing machine is one of the models that seem to attract a lot of fuzz under there, you'll need to do it again before long, even if you're using really good quality thread. By the way, try not to use the 'bargain bin' type cheap thread, it leaves more fuzz and jams up more often. I found it was no bargain, lol.

Check your tension on the machine. If it is too tight this will also cause the thread to break. This is the spring dial on the face place of the machine. Remember "righty tighty, lefty loosey".

I have a New Home Janome machine and since the needle hit a pin and broke it, the top thread now breaks. I have changed the needle and I am using good quality thread. Could it be that the feed plate teeth could be slightly damaged? It was working fine till this happened.

It could be that or the needle plate is damaged, and the thread is tearing on that. You may need to replace either or both those parts.

Check for any burrs or rough spots in the needle plate that might have been caused by your needle breaking mishap. Burrs like this can cause fabric snares and thread breaks. Burrs can sometimes be smoothed with an emery board or fine sand paper.

Have you checked the the upper thread tension? It could be too tight. If it is then you can try lowering the tension (lower the number).

If you are still having problems try using this link to Janome support as they are always helpful and also have free manuals:

I have re-threaded and checked for obstacles. I am still having thread breakage just under the foot, but only with 1 type of thread. I used another thread, different spool, same tension but no issues or thread breakage. It seems like the thread is stuck and breaks just at the foot. Is there a possibility my spool is too large? I was using a Essentials cotton thread with 1200 yards vs a standard spool of all purpose thread with 220 yards.

Yes - your spool is too large. But only for the spool pin on your machine:) What's happening is the weight of your large spool is dragging down the machine feeding the thread smoothly through the tension discs and needle. Once thread meets fabric through the needle action the accumulated strain causes your thread to snap.

You can buy freestanding cone holders and they work a treat for feeding (and safely supporting the weight) of cones AND those super yardage sized spools on the market today. Most people don't think of cone holders as useful for regular sewing machines because these cone stands are marketed towards serger owners but a serger isn't the only place for a cone holder - I own two cone holders but I don't own a serger:)

The cone holder supports the weight, feeds the thread properly through upper thread paths down to the needle and fabric - you don't have to use cones, your short stout spool of thread will be supported and feed just as easily on the cone holder as the taller cones feed through.

Prym and Hemline make cone holders and unless you go for the ultra fancy weighted base with the table clamp, the prices are very reasonable, usually between $7-$15USD or £6-£25 here in the UK where I live now. Depending on what country you live in, this is usually a relatively inexpensive bit of sewing kit that once you have it you'll wonder why you didn't have at least one sooner:)

Check to be sure you're using the right thread and correct needle size - particularly the needle size. What you're describing is most likely being caused by using the wrong thread and or needle. Check your user guide or any good sewing reference book (Simplicity, Singer, Butterick-Vogue) or do an online search for 'correct thread and needle sizes for (insert the fabric type you want to sew)'.

Changing the thread to a better quality can help too. I had this problem with thread I bought at walmart. I bought the same kind of thread (multi purpose) from a sewing store and you could visually see that this thread was better. Pretty much solved the problem.

What do I do if the upper thread is breaking?

By Alladin from Mahayahay

Answer Was this helpful? Yes
February 2, 20150 found this helpful
Best Answer

What to do when the upper thread keeps breaking...

*Check your user guide/manual - it will have tables for choosing the correct needle, thread, tension, and information on stitch type-length-width works for what type fabric, feed dog setting, and the very helpful troubleshooting table usually found at the end of the manual.

*Check the needle and thread - right size for the project?

*Check the tension setting - right setting for the fabric you're trying to sew?

*Check that your feed dogs are in the correct position for the fabric you're trying to sew.

If you don't have the manual, the machine maker's website usually has a free download.

If none of the above solves your issue, the tension discs may be clogged with lint. If your machine has the tension dial/knob on the outside of the machine, you'll be able to see the metal discs if you look down at/into the knob from a standing position over the machine - try some unwaxed dental floss just the way you would floss your teeth. Run clean floss through the discs (be gentle!) several times and try to sew again...

If that doesn't help, it's time to take the machine to a qualified repair tech - you either have a big ball of lint behind the tension discs inside the machine (where you should not go without training!) or more likely, the bobbin gear has worn and needs replacing.

Good luck, I hope you'll update when you find out what caused the trouble.

See my reply to your other question on this machine - this new problem is not likely related to your feed dog issue but is probably your bobbin gear, but all else in the other answer remains the same - your machine has plastic and silicone parts that have failed with age. And this second question now has me, a sewing teacher and vintage Singer repair tech here in the UK, now strongly urging you to splash out on a modern, under-warranty sewing machine. Sorry but there it is - I think your lovely 533 is past her sewing days, sadly!

I also posted a link to a SingerCo free download of your manual there but will post it again here for you:

Hi there. I have discovered if your top thread keeps breaking, your machine may not be threaded right or it could also do that if you are using cheap thread. If you feel your machine is threaded right, I would try a better quality thread and see if that helps. Hope this helps.

Frogheaven is on the right track.

But if those tips don't help it may be that you have a broken or worn out bobbin gear and that's a job for a professional repairman. He or she will be able to remove the cover of your machine and tell just by looking what is wrong, and will have the part(s) needed to fix it quickly.

It shouldn't be very expensive even if you ask him/her to do a general maintenance and check-over of the machine.

You need to consult the chart in the user manual that came with your machine. If you don't have that manual the manufacturer's website usually offers a free download even for vintage machines (older than 10 years).

Most sewing sites also post a table showing which needle, thread, stitch width/length/type and tension settings work best with each type of fabric. The following links may be of help to you (but the user manual is the best source of info for your specific machine):

Great tips on choosing needles:

So the thread breaking at the needle's eye or above it is do to the thread. Is that correct? I am using the correct size needle for the material and a general purpose thread.

My thread is still bunching at the needle's eye. I've adjusted upper thread tension and the bobbin tension. What is going wrong? Is it still the thread causing this issue?

Best Answer

Loopy, breaking bottom (bobbin) thread is usually a tension problem - have you adjusted the top tension correctly? That actually affects the bottom (bobbin) as well.

If that doesn't help it's time for a visit to the Sears Kenmore repair tech - it sounds as though the factory setting for the bobbin casing has gone off and it's a rather fiddly adjustment best left to the factory trained tech. He/she will also check over the rest of the machine, it's possible a gear in the bobbin casing has worn.

Be sure to use a poly cotton thread, looser stitch length and a needle for knits. Loopy thread on the bottom can be caused by all these things.

I own a 360 Pfaff sewing machine and am attempting to get the tension correct. I experienced sudden thread breaking and now the machine is frozen and won't move. How can I get it unfrozen?

By Joanne from Vale, OR

Answer Was this helpful? Yes
November 11, 20130 found this helpful
Best Answer

Actually this doesn't sound simple at all.

I do some repairs for my sewing students, mostly on Singers but have done limited work on Pfaffs and this sounds as though there is a broken part internally and/or thread(s) bits caught up in several places through the inside of the machine. The combination is what has frozen your machine.

This is NOT a job for a novice - Pfaff machines are rather complicated machines internally and very difficult to put back together once you've pulled the head and removed a couple of those tiny screws - each screw has its own special designated place even though they do look similar, it's too easy to put the wrong screw in the wrong place and that is a sure machine killer.

Take the machine to a qualified repair tech, preferably one whose advert includes the term 'Pfaff machine repairs' so that you know this is a tech with experience. The work is not going to be 'cheap' but it is going to be reliable.

Bobbin thread breaks

1. There is a right way & wrong way to insert the bobbin in the case --when you insert the bobbin in if it doesnt stitch correctly turn the bobbin over see if that helps or bobbin case is not inserted correctly

2. Lint has collected in the bobbin holder

3. The bobbin is damaged & doesnt turn smoothly

4. Lower thread tension is two tight

Why does my sewing machine keep snapping the needle thread? It is good quality thread, the machine is threaded correctly, and the tension is correct. (I think, though I find this difficult to believe.) Also, for no apparent reason, the needle function will suddenly seize up and foot pedal won't move it. I have to turn it manually. Any ideas please?

My 30+year old Singer was doing that-turned out to be a broken gear inside the machine.

I tried everything else first: changed needles, to a brand new spool of thread and bobbin thread, adjusted tension (including the bobbin tension), a few other things I can't recall now. Nothing worked so I Googled, LOL, and found out the reason thread breaks and the machine won't progress might be a broken bobbin gear.

Had my machine out to the elderly man who used to work in the Singer factory where my lovely old machine was built (I live in Scotland). I had the machine back in a week and it's run beautifully since.
