Dryer would not operate

I removed the two screws underneath the lent trap the removed the two screws that held the dryer switch assembly. I then lifted up the top and disconnected the door switch assembly. Removing the door switch assembly was the toughest part, and it was not difficult. Simply grab a pair of pliers and pull. I the attatched the new door switch assembly and the four screws and my dryerwas as good as new. I paid around $20.00 including shipping and saved myself a couple of hundred dollars
