Hi, thanks for using JustAnswer.com. If the dryer will not restart, there is a thermal fuse that is likely open. If the filter is on top, the fuse is in the back. If the filter is in the front by the door, the fuse is in the front. With a model number, I will be able to provide you with accurate, model specific information.
Page 15 shows how to remove the panel. The entire service manual will aid you in the diagnosing of your dryer. I will be around tomorrow if you are available.
