Water dispenser valve

If your water dispenser will not shut off then it is either the dispenser microswitch or the water inlet valve in the back of the refrigerator. Here is link that might help http://apcoappliancerepair.wordpress.com/?s=water+dispenser . Would need a model and serial number to assist you more. Good Luck From Apco Appliance and Air .

Your water line could be frozen in the door. You can disconnect the line under the unit before it goes into the door at the bottom hinge. Push the dispenser button and see if it comes out there. If it does leave the door open till it thaws. Covering the opening with a blanket will prevent the loss of cold in the freezer. . GE makes a heater that will prevent this from happening again. The part number for this heater is WR49X10173.

disconnect the line to the water dispenser at the water inlet valve on the back where the water supply comes in and try the dispenser. if you hear the valve work but water doesn't come out, the valve is bad. If you don't hear the valve, the dispenser switch is bad

The water inlet valve(where the water supply connects to the back) may have been staying open and now has burned so it don't work at all. . You can swap the wires on the dual water inlet valve and disconnect the water line at the valve which goes to the ice maker. When you try the water dispenser the water will come out there. When you stop the water dispenser, if the water at the valve doesn't stop, the valve isn't closing so you'll need to replace it.

Hi copy;
You may like to try the Water Valve (Solenoid) sounds like it may had stuck once now has become free and stayed open allowing too continually flow. It is behind fridge where the mains water is connected into fridge... Cheers

When you try the water dispenser the water will come out there. When you stop the water dispenser, if the water at the valve doesn't stop, the valve isn't closing so you'll need to replace it. If it does stop after trying it several times then the problem is with the ice maker

possible frozen water supply tube behind fountain assembly, or broken tube at valve, bad valve, filter,filter mount assembly

You push the water dispenser lever in and it applies power to an electric valve (solenoid) which opens and allows the water to flow.
So, there are two components to look at: 1. the electrical switch attached to the lever; 2. the solenoid valve.
Secondary things to check: Is the water connected? Is the shutoff valve on the wall open? Is the tubing clogged with mineral deposits? Are any wires for the water dispenser switch or solenoid disconnected, chewed through by that dead (electrocuted) mouse under the refrigerator?

Hope this helps...
Good Luck!

Something from the filter went into the dispensor valve and is holding it open. You can try to backflush it with a can of air by disconnecting the filter pushing open the valve while holding the can straw tightly while discharging it. You could also backflush it with water.
