Shelving went in without a problem. Very simple. Checked the installation video anyway in case there was a trick to not breaking something. Learned that the nylon clips needed to be transferred and found one missing on another shelf, so ordered a replacement. The water valve was one I replaced some time ago but one of the solenoids was bad, confirmed with a meter (ohm reading is between 200-500; less than 200 or more than 500 is broken). Replaced it without a problem (becoming expert at it!). Problem with the water persists, checked all the other lines but isolated a clog in the line inside the freezer door. Ice works so will postpone replacing refrigerator. Most of the tools/time was for the clogged line trouble shooting. The valve took less than an hour.
