My sewing machine will not change patterns. stays on a pattern i do not want. need it on straight stitch. is there a part i can order for this problem?
Though I am not familiar with your modern Euro-Pro machine, some of the general advice I would give for the same problem on vintage "mechanical" machines may very well also apply to the newer "plastic" machines if the problem is mechanical and not electronic. If it is a mechanical problem, like the Stitch-Selector Knob being loose, out of adjustment or broken, or some thing in the mechanical linkage gone wrong, then you may be able to fix it yourself.
(1) Open the machine to access the inside of the top portion of the machine. This may be difficut on a newer machine.
(2) Find the CAM stack (those round disk-shaped Cams with the bumps around the outside edge). These control the stitch pattern, by controlling the needle swing-arm movement.
(3) Observe how the Stitch selection knob selects the built-in disk Cams.
Plan A: Jiggle the knob and follow the activation chain to the problem. If you can locate the exact point of the problem and re-adjust it, you are home free; if not, go to the next Plan.
Plan B: Manually change the Cam selection to Straight-Stitch (if that is what you want at this time). To do this, mimic what the knob mechanism does, or is trying to do. If that is not evident, then turn and/or lift-or-lower the selector or follow-finger, so it rides on a Cam that makes the kind of stitch you want. Sometimes a Spring that holds the follow-finger along the Cam edge comes loose, and you may have to devise a way to reset it so it holds the finger along the Cam edge. Also jiggle the Cam and linkages, to see just what each one does. It is most likely an adjustment and not a part that is needed (of course, unless a gear is striped or broken). Be sure that turning the Stitch-Selection Knob fully activates the chain of moving parts to make a change at the Cam stack. Find the brake in that chain of movements and you have found where the problem is.
Plan C: If possible, find a similar machine (or clear diagram/photo), and compare the knob movements and the linkage path to the Cam stack. Make yours like the model that works, and you have usually solved the problem.
Plan D: If you cannot solve this with these general instructions, maybe someone you know (hopefully sooner than later) with a high mechanical aptitude can resolve your Stitch-Selector Knob "Disconnect" malfunction.
Good Luck, and May God Bless Your Sewing. -- Amender.
