Why is my Viking Prisma 940 only sewing straight stitch - none of the patterns are working

SOURCE: Sewing machine straight stitch is not straight

Hey. It's full out possible that you have it on the right setting...but concider this - the switcher inside the sewing machine could be broken (ie. It's moving to different stitches - but not the one you have the outside set for)

It happened to me (pc o crap singer model)

It must be a design flaw- things don't always last like they are supposed to. I would personally check the physical reason it is not responding... knowing what it would take to make it stop moving- or whatis causing it to. *perhaps the switch isn't working to stop it- or the mechanism that controls it is worn down. If it was new- I'd return it- but there are only a few options at this point.

SOURCE: Husqvarna Prisma 980 decorative stitch cassettes don't work

Hi,
On that machine, the cassettes aren't actually computer chips. Each cassette has a little spot of white on a certain little area you must find (top right I'm pretty sure). Look in the machine at that point. There is a sensor that looks for that white spot, and as it identifies it, it changes stitches according to that cassette. Either the sensor is blocked, gone bad, or you can put a fresh coat of white paint on with white out. I hope this helps.

I would start at $750.00 That would cover the basic replacement cost of the machine.

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.
