Product review (5 stars): You Gotta Have Ice in the South
Our Icemaker stopped working, and the water line was frozen.  I read online trying to find what could cause the line to freeze, and none of those things seemed to be the problem.  Finally we did what should have been done in the first place, tested the icemaker with a meter.  It was dead.  We ordered this one and installed it rather easily.  Works great now, and we have ICED tea instead of hot tea!  Disclaimer..by "we tested"  and "we installed" I really mean "Hubby tested" and "Hubby installed".  Others might not be able to test and install this yourself, but you can save a bundle if you are able to do it yourself.
