If the water valve is bad, would the icemaker not get water to it but water still dispenses from the door?
Answer Hello Clinton,
The water valve is a dual valve. One side is for the ice maker and the other is for the water dispense. In light of this information it is easy to see that either can fail without affecting the other side.
Installation and location of water valve wr57x10070
Normally the water valve for a refrigerator is located on the back of the unit. You would pull the unit out and remove the lower cover to access it. With the model number of the unit we could provide more information. Please post your model number with a new question on the parts page. http://www.appliancepartspros.com/modelnumber_locator.aspx
