I received the timer the following day and within 15 mins.my dryer was working again. It was easy, I simply placed the new timer obove the old one and removed one wire at a time from the old timer on to the new, done.First making sure that the knob was on the off position before removing it.Reverse the steps on removing the old timer and there you have it...like a pro.Thanks guys. Very helpful, all my questions answered. thank you Nancy. Joe M Moreno
