I just bought my PQBrothers 1500s in Nov. and haven't sewn on it that much. I made the quilt blocks for one quilt and started some blocks on another one but hadn't sewn since around Christmas on it. Yesterday I went to show a friend my machine and turned it on and was changing over to the free motion foot and noticed my light went off and lost the power and it won't come back on. I cleaned it and oiled the places it said to oil and still nothing. Just can't figure out what happened. I wasn't even sewing on it. It said in the book to check all these things on the trouble shooting page so I done that and then the last thing says, the automatic safety device has operated. I don't understand why for I wasn't doing anything but changing the foot. I loved the machine and was so happy with it. Was just wondering if anyone else has had any problem like this. Please Help! Trying not to get discouraged. Would be thankful for any help.
