Buttonhole This is a 4 step buttonhole machine. When I get to the third step (which is when the left side of the buttonhole is about to be sewn, going up) the machine hangs up and the fabric doesn't move. I don't know if it is the feed dogs or not. It works fine for straight stiching. I've cleaned it and tried different types of fabric and neither seemed to help.

Make sure you are using a needle size compatible with the weight of the fabric you are using. Make sure you chose correct stitch dial for the side of the buttonhole you are attempting to sew. Make sure you have buttonhole foot properly attached.
Hope this helps.

I'm afraid that you are unable to correct this glitch on your own. Any sewing machine service center/shop will do...call around and look for the shop with the lowest 'minimum' charge. It is such a simple fix. However, although simple, the adjustment is so incrementally precise that without thorough understanding, your stich patterns could be rendered unuseable. I have no idea of the current value of your sewing machine, but if you deem the repair costs prohibitive, there is a workaround so you can complete your buttonhole. Complete your buttonhole setup as normal. I assume that you run tests first to adjust your stitch length/density of the buttonhole using the Step 1 setting. When you find the the length/density that you want, using an ink marker/crayon...whatever...being as precise as possible, mark a linear line from the edge of your length selector dial, continuing to the body of your machine. Now, select Buttonhole Setting #3, and increase the stitch length until you see the length/density that you want. Find a clear spot on your length dial and repeat the marking procedure. When you are ready to make a buttonhole, align the markings for Buttonhole Step 1 on your stitch length dial and proceed, complete your tack of step 2, stop, manually raise your needle out of the fabric using the balance (hand) wheel on the right, adjust your stitch length dial accordingly for Step 3, then on to your final tack #4. If it's only your buttonholer that is giving you trouble, take the extra 15 minutes or so, and use the workaround and mark your machine. It doesn't have to be ink, it can be pinstriping tape...whatever, and spend the money you saved on fabrics and notions instead.....good luck my friend.
