ok i bought this fridge used and all the water lines were disconnected and i had to figure out how it worked and where they went too anyways there are two water valves on the back ok the main line comes in and two lines go out to the filter in the fridge and then out of the filter to the other water valve hit the water in the door nothing so it got me stumped why there is no water so i tested the water valves using 120v wires and boom the water valves open so not the valves so i researched further into this problem took the door appart and found the control board tryed to test the resistors and they all seem fine but there is a relay on there now will that control board send power to the water valve i also checked the mico switch and it works so now i am stumped and help would be great thanks
