Juki 5550n-7 Powers on fine, lifts foot peddle when pressed but will not sew.
Hey there, I don't know if this will work, or if it's even the issue, but I've had all the same issues at one time or another, and every time it was the same easy fix. Got to the back of your machine and put your hand on the motor and see if it moves with a wee bit of pressure. If it moves about, then that is likely the problem. Find the bolts or screws that allow you to adjust the swing position of the motor. You'll want to pull it toward you until there is just enough pressure on the belt to allow all the mechanics to work. Too much pressure will add premature wear and tear on your belt, as well as other moving parts. Hope this helps. Let us know if it doesn't, someone else may have some ideas:)
