Singer 5050 will not sew a zigzag stitch. Can move the lever all the way over to the full zigzag width and it still only sews straight. Please help if you can.

    Model : Singer 5040

    Problem, Will Sew Only Straight Stitch at approx. 1 1/2 inches. If I change the width to zigzag ( any width) no effect, if I change stitch legth ot any other length - No Effect.

    I opened it up top to ensure no broken / loose parts & I oiled it down. I open it up from underneath to ensure no broken / loose parts or stuck fabric / thread. I also oiled it below as well.I replaced the bobbin case - obvious wear marks on the old one, I changed the needle two times and the thread & bobbin ( rewound another bobbin ).

    None of this had any effect but I did notice in programmed stitches I can get a zigzag so it can't be that it isn't able to stitch the zigzag, just it isn't doing it for some reason.

    I am trying to make a button hole but instead of zigzagging it sews a straight line. How do I fix this? I have lever pulled down with button image on it as it beeps if I don't.

You must adjust the program control, to the zig-zag position also.

I was hoping you would have got another answer, I have a mechanical sewing machine ( Singer 5040) with the exact same problem. However, if i use the programed stitches I can sew a zigzag. If i do it manually and set the zigzag width to any width ( even the widest) I get only the same straight stitch, and no mater what length I select it is the same too, very close to gether about 1 1/2 inch stitch.
I took my entire maching apart to expose inside both top side and underneath, nothing apeared loose or broke and i oiled it up. I bought a new bobbin holder and still the same effect. So it has to be something serious is my conclusion...sounds like a trip to Sears to me...LOL

Singer quantum will not turn on

Have you looked at your manual? I think that you would have to pick a stitch pattern, ie. straight, zigzag. Then width and length for the machine stitch. Now, press on the foot pedal.

Will not zigzag or decorative stitches. New to these newer plastic style machines Always used older steel machines. This was given to me my by my sister who used it very little. Could cam be broken?

Hmm, I'm wondering if it has been cleaned and oiled recently. Older mechanicals require frequent TLC. Consult your owner's manual for cleaning and maintenance instructions:

Is your sewing machine mechanical (ie, not computerized)??? CAUTION--if your machine is computerized, do NOT proceed with the following suggestions.

If it is mechanical, have you cleaned and oiled your machine recently? Most mechanical sewing machine failures are because they have not been adequately and routinely oiled, the old oil has solidified and frozen the mechanics. I recommend Bernina oil or liquid Tri-Flow Synthetic Lube (or similar good quality sewing machine oil) for mechanical machines--do NOT use 3-in-1, cooking oil, WD-40, or the sewing machine oil from your grandmother's sewing basket. (I am not associated with any Bernina dealer.)

If it is in fact frozen, pick up a bottle of liquid Tri-Flow Synthetic Oil at the hardware store. Oil one or two drops in every oil hole (see your manual) and also every place where metal rubs on metal. But DO NOT oil any plastic gears, rubber, or belts. If it is still stiff or frozen, direct a hot handheld hair dryer into the top and bottom mechanism of your machine. See if that loosens it up. You may have to repeat.

Once your machine is working again, place a drop or two of good sewing machine oil as directed above. Be sure to use a small brush to clean the lint and dirt out of your machine, especially around the feed dogs and bobbin area. (Caution: Compressed air will sometimes force the dirt and lint into areas that cannot be cleaned.) And continue to use good quality sewing machine oil to keep it running. Recommendation: every time you change a bobbin, after 8 hours of sewing, or every six months if it is not in regular use.

Singer 4411 sews fine forward and reverse in straight stitch, in zigzag top thread looks fine on top, but all loopy underneath and will only reverse stitch 1 or 2 zigs or zags

check that the bobbin underneath has the same thread as the upper bobbin and that you push all the way on the lever when sewing back and also, go full speed as this happened to me and that was my mistake. Hope this will help you :)

Can this machine do zigzags?

The Sew Dlite 11401 shown on Amazon here, , does not do zigzags. It only does straight stitches. There are similar models that have a stitch width lever. Those do zigzag stitches and straight stitch when in the zero width mode.

I hope this helps.

I have a singer 5040c and it won't do a zigzag stitch - it just goes in a straight line.

My wife just had this a similar problem with her Singer Omega 36 where she could sew straight and select patterns but could not zig zag. If you open the top of the machine you can see where a little lever connects to the white plastic pattern module that gets inserted in the top. The reason for the problem was that the lever was not touching the bottom of the module properly. The notches on the module cause the needle to move from side to side creating a zig zag. The module needs to be inserted correctly, by this I mean fully and the correct way around or it does not reach the lever when it is in the A position. At first inspection it looks the module could be inserted any way around but there is a thin and a fat clip. You need to try both ways to see which on sits lower in the machine. You may now need to adjust the tension on the machine as the lever will nowe move differently inside the machine. This fixed my wifes problem.

Singer machine needle won't do width in zigzag

It sounds like it needs lubrication on the needle bar frame and linkage.

When making a straight stitch or Zigzag stitch, makes loops underneath the fabric This is for a Singer sewing machine model 5817c

Your top tensioner is too loose.make sure the thread runs through all the relevant eyes and then tighten the top tension little by little as you do a sample few stitches.
