We reviewed the videos & ordered the parts figuring that it was the heating element but, since thermal fuse was only another $10 decided to replace as well since these were the 2 main causes for our issue. The whole process took about 4 hrs for us to complete. The videos were awesome as to directions on taking the dryer apart & putting back together. However it does not show how gross the inside can actually be. We had about 5 yrs of lint inside the main compartment & front door panel. So if you are going to do this make sure you have a vacuum or shop vac b\c you will be doing a lot of cleaning. Also some of the nuts were tight so if you have a power drill it would make things easier.
