I promised a friend I'd do some mending for her. I have to go see her today, but the last time I tried to use my "fancy-dancy" very expensive sewing machine, the bobbin winder didn't stop when I wound the bobbin and then I couldn't get the machine to engage in the sewing mode. Figured it was because I was tired, trying to sew at night, etc. So, I thought "this should take about 5 minutes to do" (a sun-canopy had two corners that needed sewing). Wrong. Still couldn't get it to engage in sewing mode. Rethreaded it, re-inserted the bobbin, changed the needle, stitch length. Nada. Went on line and found a few posts where the problem was described exactly as I would have described it. Although the machine is "no oiling required" the bobbin winding post DOES need oil. Fortunately, mine isn't seized, but it was stuck in the "bobbin wind" mode. Once I got that fixed, the sewing mode engaged. The sun canopy is fixed, bathing suit is in my bag (she has a pool) and I'm on my way. Gotta love the things you can figure out how to fix/diagnose thanks to the Internet. My thought was a belt might be slipping, so trying the easier fix (and definitely the no-cost fix) was step one. I didn't have to go to step 2 and run out and get a belt, open the machine, etc. This makes two simple fixes (the A/C fan switch and now the bobbin spindle not disengaging).
