LG TROMM dryer quit, dead

Dry way running with light load then quit. checked power to dryer then, all accessible switches with ohm meter. the heat element included. Im down to the main electronic panel and motor. No burn signs on the main panel, however, there is a slight overheat smell coming from the little transformer mounted in the center. I dont know how to check the motor. any support out there? i do appreciated all the help I can get. Jack
