Dryer will stay on as long as the on button is depressed.The motor relay is not being energized.holding button in will run as long as a cycle is chosen.Checked wiring no noticable problems.It would be great to review schematics to chase down all safteys before I replace control board or a test procedure to accomplish the same.

The technician sheet and wiring diagram should be in the control panel.

Here is a link to the parts of your dryer model 110.64972301.
