First, I removed the old parts, there are 3 parts to the dial that was broken, one of the pieces stripped and I only had to replace that part. After taking them apart, I used the new piece, the Timer Dial Skirt, and put the 3 pieces back together. Easy as pie. The only trouble that I had was when I received the new part the first time, it was broken also and I had to order another one, which they got to me right away. Although, they did make me pay for shipping the 2nd time around.
They need to package them better, this was just placed loosely in a plastic baggie and the shipping company did not treat it well. Other than that, everything was very easy and quick.
