The water filter should be replaced about every six months to maintain proper water flow and ensure water quality. If a dispenser switch does not have continuity, replace it.Ī clogged water filter can restrict the flow of water to the dispenser and prevent the dispenser from working properly. To determine if a dispenser switch is defective, use a multimeter to test each switch for continuity. If one of the dispenser switches is defective, the dispenser will not work. The dispenser switches send voltage to the dispenser. If the entire dispenser system is not working, the control board is more likely to be at fault. It is more likely that a single part has failed. If only one dispenser part is not working, test each of the dispenser components before testing the control board. If the control board is faulty, it may stop supplying power to the entire dispenser system. The dispenser control board governs most of the functions of the dispenser system. Check the water flow and test the pressure to determine if it is at least 20 psi.

The water inlet valve requires a minimum of 20 psi to function properly. The water inlet valve supplies water to the water dispenser. The home may have insufficient water pressure. If the water inlet valve does not have continuity, replace it. If the water pressure is sufficient, use a multimeter to test the water inlet valve for continuity. Make sure that the water pressure to the valve is at least 20 psi. The valve requires at least 20psi to function properly. If the water inlet valve is defective, or if the water pressure is too low, the water valve will not open. The water inlet valve opens to supply water to the dispenser. If the freezer is too cold, the water line may freeze. The freezer temperature should be kept from 0-10 degrees Fahrenheit. In addition, ensure that the freezer is kept at the proper temperature. If the water supply tube is frozen, thaw it out. If air does not pass through, this indicates that the water supply tube is frozen. To determine if the water supply tube is frozen, disconnect the tube at the bottom of the door and blow air through it.

Is a line still frozen? broken? How do I identify the line? Is it visible when I remove the back panel in the back of the unit? How to thaw, if frozen line?Įdit: Line appears to not be frozen, as I can blow through it using a straw as well as feed a weed cutter line completely up into it. So, end result - no water and it appears it pours into the fridge under the drawer. I unplugged the refrigerator and used hot water repeatedly poured down the drain hole. Now, when I was doing the water filter housing install, I also cleared the drain line behind the inside-fridge back panel, which was frozen, as there always was a pool of water under the deli drawer. Now, if I look under the wide deli drawer, which I removed, I see all that water pooling on the surface. When I place a glass against the push valve to deliver water, I hear good flow noise, as though water is being sent through. I then replaced the water filter housing (that the filter screws into, has the two water lines - 1 goes into the water source from the wall, the other into the water valve). I hit ebay, purchased and installed Refrigerator Water Valve for GE WR57X10091. He came out, determined that it was a faulty Refrigerator Water Valve. Anyway, I changed the filter to a GE factory filter. Both water and ice stopped working, I believe after I changed the filter, but not certain about that.
