I have a 4022 Singer that does straight stitch but don't know how to make it do fancy stitch. Can you help?

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

SOURCE: Singer 8280 is not giving me a useable stitch due to tension is not properly feeding resulting , no interlocking

Make sure that the thread is not getting caught on the handle. I was having the same problem and tried everything only to find that my thread was caught.

I had a similar problem a couple of years ago. I finally figured out that I had the straight stitch needle plate (the one with the single hole), rather than the zig zag needle plate (the one with the curved hole). When I changed plates, it worked fine.

I hate to say it, but the 6690 was plagued with circuit board problems. That machine cost Viking a lot of heartache. I'm a bit surprised to see one still working. You didn't specify exactly what you did when cleaning or whether you took the covers off and disturbed the wiring. Check all the connections and plugs, but it might be dead. You can take it to a Viking dealer with experience with the 6690 for an evaluation.

SOURCE: i have a singer 5040c and it won't do a zigzag

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.
