Product review (4 stars): Replaced in about half hour, detach screw to make it easier to work with, you can pull it out then and attach hoses and wires.
A lot easier to do the replacement if you unscrew the one screw that holds it to the frig and pull it out, then you are not trying to work in such a tight space.

Be sure to label all the hoses and connections so you know how they go back on.  For two hoses I had to pull out the hose rather than cut it off because there was not enough slack.  Did this by gently prying the circle at the connection up with a screwdriver after removing the black plastic clip (save these, there are not new ones with the part).

The white wire harness has two little clips you need to pry up to remove, the other 3 just pull out directly.

So far, no leaks and frig and icemaker are getting water again.

I have attached a few photos so you can see how awful mine was and in case you forgot to label your parts before you detached it, must have been a slow leak, lots of calcium carbonate build up.

While you are back there, blow out the dust off the coils with some canned air.

One star off for no instructions at all and no new plastic clips.
