Product review (5 stars): Universal Fit and Solenoid / Coil! Replace the coil by itself on other models!
I have an Amana refrigerator and discovered my ice-cube-mold-tray was deteriorating. So I replaced the tray and then the water is not filling the ice cube mold with water. I looked up the replacement valve and discovered it was anywhere from $40 used to $90 new and thought how unacceptable it is that I can't just replace the coil by itself!

So I found this unit on Amazon for a good price, at $20, and thought to myself that I would just "steal" the coil from it and put it on my valve. Turns out, my theory was correct and it worked out great!

Pictures:
1. My green coil was bad and had no continuity whatsoever. The green coil on the "Robertshaw" item here on Amazon was not the correct replacement one, instead, the red coil was the proper match. I swapped the red one from "Robertshaw" into my valve and it worked great. This required bending the metal and breaking the "Robertshaw" one, essentially.

2. The red one is pictured (looks very orange, however, in the picture). This is the "Robertshaw fitting just fine in my Amana fridge model "TR21VW". Other models that it should work fine with, simply on the basis of assumption, may be the models that have this ice cube tray: (Part Number WPW10190929 (AP6016623) replaces 14211407, 2255835, 627815, 627997, 628189, 628228, 628315, W10122527, W10190929)

3. Picture #3, my defective green coil / solenoid is the one in my hand, on the right side of the picture. The green one left in place of the "Robertshaw" product has the wrong size prongs for my valve.

I hope this helps any other DIY-ers out there. The coil themselves should have been sold individually but oh well.
