   not 100 percent sure of that exact rack but all the models I have seen with   
   that design is driven by the motor itself and if the motor is jammed or frozen   
   that is usually the reason why things wont move. have you tried turning the   
   shaft of the motor    
   itself.  I had a problem once with the gripper motor of my jukebox and when I   
   turned the shaft hard by hand it broke loose and started working
