The Estate Dryer was working fine.. then just shut of.. I replaced the 20 dollar therister.. however it still won't start... no lint... exhaust vent clean and clear... Timer?? Next replacement?

How did you test the thermistor? If you are just replacing parts without testing first you will never get it fixed. You may have only needed to clean it, or clean it and replace the safety that is open. You will have to remove the air ducts to clean them, like the filter holder, etc. Any one you miss will cause a restriction and another safety will blow. Here are some manuals: https://dl.dropbox.com/u/8010163/Whirlpool%20Dryers.zip

Make sure to get a good digital meter and test the parts and compare values with chart.
