Product review (5 stars): My Frigidaire refrigerator was leaking water on the floor. ...
My Frigidaire refrigerator was leaking water on the floor.  This was miserable!  At first I thought it was a faulty icemaker, until I saw water pouring in and overfilling the ice maker. So I replaced the water valve.  This didn't fix the problem either...still had water pouring over the top of the icemaker and freezing inside the freezer compartment.  Finally I saw a review about this diode kit fixing a similar problem.  I decided to try it and BINGO!  No more water leaks.  I wish I would have started with this diode, but at least I finally got the problem fixed.
