Whirlpool clothes dryer stopped heating. What's wrong?

The unit is about six years old. It stopped heating. I have changed the wall fuses. That’s not the problem. I suspect the heating element has a short in it. Question: is there a site I can visit that will give me firsthand instructions on how to replace the heating element, for free? I have changed elements before in clothes dryers. I do not want to start this project, until I have some visual do-it-yourelf instructions in front of me. Help!
