Product review (1 stars): I CONNECTED THE 3 WIRES AND DRYER IS FINE... DIY FREE.  PRODUCT WAS POS.
Product was correct part but it LITERALLY fell apart during normal installation.  In looking at the old part and comparing, I see that this replacement part was not glued together as was the old one.  Worse than a waste of time, I waited for 3 days for delivery and piled up the household's clothes.  Then, I decided to bypass the switch by cutting the wires and securing them together with a wire nut a tape.  Dryer works but does not shut off when door is opened.  No big deal since I don't have a toddler.  PROBLEM SOLVED FOR FREE.
