Electric dryer will not get hot

My dryer will run and the fan blows but it will not heat up. I prefer to make the repairs myself, and have located heating element at a local store. However, they want $90 for the element when I can order the entire element kit for $56 plus shipping on your site.

I also hate to purchase the element if there is something else wrong with the dryer. Any recommendations for self repair before I call a repairman?
