Zigzag stitch not working on top side but working on bottom side on singer 1120

My singer 1120 will not sew a zigzag stitch properly. The top of the stitch has a zigzag but with an extra line of thread underneath it. The bottom of the stitch is working PERFECT. I have checked everything that I know to check, have cleaned and oiled the machine. I have tried numerous different length and width combos and set the tension on different numbers from 0-3. IF anyone has any ideas on what I need to I would appreciate it. Thanks!!

SOURCE: singer machine needle won't do width in zigzag

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

SOURCE: I have a Singer Sewing Machine 5817C, the thread

Make sure that there is tension on the thread when you have passed it through the tension unit, by making sure the presser foot is down, and then gently pulling the thread to feel tension. If there is no tension, as seems to be the case, check the tension discs inside the unit to make sure that there is no debris stopping them from closing.

SOURCE: Singer stylist 7258, will only pick up bobbin on one side when doing zigzag stitch

try using a washable stablizer or interfacing.
if that doesn't help then it's possible that a gear or cam may be worn enough to cause the machine zig zag not to work properly

Bottom thread is still loose even if i try to balance the tension, how do i balance the thread tension?


You bobbin tension CAN be adjusted. First, thread your machine with different colors in the top and bobbin, set your top tension at its default, and run a line of straight, and then a line of zigzag stitches, and compare the results at the top and bottom. You will be adjusting your bobbin to your top tension. If the top tension looks like a straight line instead of stitching and the zigzag looks like "chicken tracks" instead of a zigzag, but the bottom looks like a zigzag, your bobbin tension is too loose.

Remove the bobbin case, and locate the straight-slot screw. There are generally two; one is a Phillips and one is straight--you want the straight one. Leave the other alone.

The rule is "lefty-loosy, righty-tighty." If your stitching displays the above symptoms, it needs to be tightened, so turn 1/4 turn to the right--no more--then test again. You will need patience, but don't turn more than that. It is easy to do, but if you don't do it systematically, you can make things worse, and very slight adjustments can alter the stitching significantly.

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 :)

I cannot get tight tension on zigzag underneath stitch on my singer 3221


There are a couple of things to check. First, did you thread with the presser foot UP, so that proper tension is applied to the upper thread? Is your bobbin correctly inserted, and is your bobbin case inserted evenly and correctly? Review your user's manual--if you don't have it, you can download it free at the Singer website.

If you have done these things, you may need to adjust your bobbin tension. First, run a line of straight and then zigzag stitches on a scrap of fabric and take a look. It helps to have two different colors of thread, with the fabric a third color. If one side of the zigzag looks fine and the other side looks like "chicken tracks," the chicken tracks side is too tight. In other words, you need to determine whether your bobbin tension needs to be tighter or looser.

You'll need a very tiny straight-slot screwdriver. Remove the needle plate--there are two screws in it--and remove the bobbin and then the bobbin case. On the side, there are two tiny screws. One is a Phillips--leave that one alone. The other is a straight-screw, and that one regulates the bobbin tension. The rule is "righty-tighty, lefty-loosey." Only turn it 1/4 turn, then reinsert and test. If you're on the right track, you should see at least a LITTLE improvement. DON'T do any more than that--if you don't do this carefully and systematically, you'll make things worse instead of better!

Not stitch zigzag


Have you tried a needle change? It could be blunt or the wrong size. Have you cleaned under the needle plate as the ridges get full of lint there. A toothpick will clean them out.

Singer 5050c top thread coming out of tension control during sewing


What if you get a thread stand? does it happen when stitching vigorously or normal stitching? Thread stands helps keep tension and avoid thread jumps etc...

When I use my Singer model 1120 for sewing straight lines, the thread bunches up underneath. What is the problem?


Be sure that the machine has been cleaned and oiled. Check to be sure the machine is threaded correctly. Check to make sure the bobbin was wound properly.

My old Singer sewing machine won't pick up the bobbin thread. It is threaded properly and goes down to pick up the bobbin thread, but comes up with no bobbin thread. What to do please?


Hi, try re-timing the machine. Select "straight stitch," then take the bottom off the machine to see underneath the bobbin case area. Open the faceplate and look for two marks on the needle bar around where it enters the machine. Take out the bobbin case to see the hook. Turn the balance wheel toward you so the needle is going down. Stop turning when the needle is just about to start on its way up. The bottom mark on the needle bar should be just about to enter the machine, and the point of the hook should be just above the eye of the needle. If it isn't, tilt the machine backward and loosen the two screws on the vertical gear so you can move the hook to where it should be. Tighten the screws and put everything back so you can test your setup. If it sews a straight stitch correctly, try it on zigzag wide stitch. If it misses one side, repeat the timing process.

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.
