Do you have the 530-2? Maybe you could describe how you "unfroze" your machine. I am so disappointed that the guy I bought this from said it ran and it might need a service but never said a thing about major parts being frozen. I'm never buying a machine online again from a "non sewer". When I pointed out the issue his response was, "I was perfectly clear in my description and I don't sew". Silly me, I thought he was an honest seller...he also said he took it to a service place who said it could have the problem I found. Then why not share that info? I know why but it's Sunday and I just want to get my little Bernina working.
