My singer 14u52a seems to be locked up. The motor is trying to run but the needle won't go up and down. I've put the oil in as described in the manuel.

Do you have a bunch of material and thread stuck in the feed dog? Sounds like. This will sometimes happen. I'm afraid the only thing you can do is carefully work with a seam ripper or small scissors to get it all out. Be careful working. You will damage this part of your fabric, but you can take the seam allowance in a small bit. You will probably have to remove fabric & thread from underneath, through the bobbin area, too.

Once you have all of this cleared, the needle and wheel will turn. I suggest you try and take the needle out of the shaft and try pulling it out of the fabric before you start your work, too. That way, you won't risk breaking it and have a piece fly off at you.

It's frustrating and will probably make you curse at the machine-it's happened to everyone who sews at one time or another, and will happen again, I'm afraid.
