Kenmore Dryer No Heat

I have a Kenmore Dryer purchased in 2005. The heat just quit working on it on Sunday. The machine operates but with no heat. I have read some of the posts as far as what to look for and check but am still totally lost. I have located the heating element and I think I have located the thermal cutoff and hi limit thermostat, but not sure where the thermal fuse is. How do I check these to make sure they are working? I am an EXTREME novice and this is the first dryer repair EVER attempted.
