I am getting ready to order my third inlvet valve from Appliancepartspro. Could there be something else wrong with the icemaker? Each time it "breaks" it starts dripping from the water spout on the door, then quits making ice or half fills the tray. The inlet valve cures the problem every time. This last valve lasted less than 6 months! What's going on? I do not have a water softener on my home but the water is within normal to hard range. Half of the neighbors have a softener, half do not.
