The water to our refrigerator was not turned on when it was installed and I am now trying to get the ice maker working. There is what appears to be a water hookup behind the refrigerator but turning the handle seems to have no effect. How do I operate this valve?
Sometimes called a cock; it is a 90 degree turn ,open/closed. The handle shows the position of the plug opening ( if it is not failed). When the handle is in line with the copper line ,it is open. When the handle is pointing to the side , it is closed. The picture looks like it is midway between open and closed.
