I have this problem, the dryer will not start, when u puch the start button, all it does is click. I have checked for cotenuity at door switch and start button. I repalced the thermo fuse, same situation. Any suggestions??

Have you used a meter to find which safety is bad? It has several and unless you want to replace every part on the dryer you will need to use a meter. Here are instructions: https://dl.dropbox.com/u/8010163/Whirlpool%204322537A%20How%20to%20use%20Test%20Equ ipment%20Service%20Manual.pdf
