Product review (5 stars): if you need to replace an old triple circuit Kenmore/Whirlpool and it's not sold anymore, this might do it for you...
I'm guessing I can't be the only person with an older Kenmore/Whirlpool refrigerator.  After 16 years, the icemaker stopped making ice.  And after narrowing it down to the water valve inlet I found that the part (part #2206123, model# 106.59212990) isn't sold anywhere.  I was about to give up when I found another review here for someone who had the same problem and fixed it with this generic replacement.  I'm only writing this here because it finally fixed my issue after a lot of time spent trying to fix it.  The Kenmore we have uses a triple circuit and this one is only two, but if it's one of the two in back that has the problem this will work.
You can test the existing solonoids with a multi meter to see which one is bad - go to youtube and search for how to test refrigerator solonoid with a multimeter.  Then basically I took out the entire assembly and replaced both solonoids that are together with the new ones.  You have to do a little bit of screwing/unscrewing to get the old ones off, but it's pretty straight-forwad.  The main piece of advice, which I didn't heed myself, is to use your cell phone to take pictures as you take out, and take apart the old water valve - if you're like me and have never done this before, the pictures are a big help when you're trying to remember where certain things go.
Also, check the part numbers - although mine is a Kenmore, it's made by Whirlpool, and it's in several other brands which may have different part numbers even though they're all identical.  So, if you have one of these older triple circuit refrigerators and really want ice made again, this may do the trick.  Oh yeah the other thing is that even if I found the original part, it sold for about $75....this was about $13...big difference.
