My problem is that when the timer is in the position of the elements are in heating on the dial, ex. Minutes of drying, even with the door open. The elements continue to be hot and active. Only time I see that there is no heating is when the timer is in the off position on the dial. Could this be the timer? Came home with the elements on and the top of the dryer was very hot. We were able before this in the middle of the drying process open the door take clothes out close the door and have no problem with heating with no drum spinning. Please tell what part I need to get.
