I have a Kenmore sewing machine model 385.16231that is only a few years old and it has has stopped working. I was using it a lot this morning and all of the sudden it just stopped. I figured that it just over heated so I let it sit for around for around five hours but it is still not working. When I flip the switch to on the light comes on but it will not sew and this issue is not stated in the troubleshooting section of the owners manual. Can anybody help please?
