I have had my Brother 1500 in the shop twice now for the same problem. The guy said well it worked fine when I tested it. He sewed about six inches on a piece of sample fabric and called it working. He kept the machine for four weeks. I took it to another shop, not a Brother dealer, and the guy fixed it in one hour. Said the first repair guy didn't repair it, he rigged it to work hoping it would hold up for awhile. It's frustrating trying to find a decent repair shop.
