From what you are describing, it sounds like you need a valve. Another common thing I run into is the cooling tank inside the fridge freezing. This will usually affect water through the door only. Remove the crispers and you should see a large coil of plastic water line attached to the back wall of fridge. You can check to see if it is frozen by blowing through it from the end of the line you removed from valve. BEWARE, if you blow through it, water will come out dispenser if line is not frozen. Have a towel at front of fridge.

There's an ice- or water-dispensing problem The ice and water-dispensing system of your refrigerator is quite complex. Many components work together to provide the ice and water. Aside from a simple problem of a leaky water tube or a jammed ice chute, most other components are not user serviceable. We suggest that you contact a qualified appliance repair technician for such repairs.

It's quite possible it is plugged by hard water deposits forming in the supply line as these lines are quite small. You can check if it is plugged by shutting off the supply line and removing it. After removal turn it back on but have the end in a bucket in case the blockage is in your fridge unit. If water comes out it is in the fridge. Usually there is a screen to prevent large particles from entering. Make sure that is clean. Try these and see if that helps. If it doesn't get back to me as the trouble shooting will get more intense. I'm hoping this helps.
