Product review (5 stars): Works Great - 2 Snags During the Install.
2 snags.
First - The dial.  The timer dial did not fit on the new stem.  On the old part, at the bottom of the dial stem was a black collar or sleeve.  Slide this off and place on to the new stem. Now the dial will fit.
Second - On mine, there was a large plastic piece that housed the 3 wires that connected to the part (see pic).  Getting this piece to come off was difficult.  I eventually used a flat head screw driver to pry from the bottom, then once it popped off slightly, I did the same to the other side.
