I have a kenmore elite gas dryer model #11072086101 that every thing seem to be working but its not heating any suggestions and I am also looking for a electrical diagram. Please help

You need to check out the flame rod to see if it is clean. You clean it with fine sandpaper. It is a stainless steel rod about 1/8" in diameter and 1/4" long with white insulator about the size of a spark plug and it measures electricity through the pilot light to prove the flame. If it's dirty it will not work. Here are manuals: https://dl.dropbox.com/u/8010163/Kenmore%20Dryer%20Manuals.zip

I have a kenmore elite model #110 72932100 that heats for a bite but it still run like if it's still drying.

You need to clean it out well. Don't miss anything, and wash out the parts by removing them.
