More than likely, your water line is freezing up in the door. You can remove all of the ice cubes and lower the freezer temp to about 3. Leave the freezer door open for about 5 minutes or so and if this does not work, leave the door open a little longer. Also, disconnect the water line at the base of the freezer door, near the floor, and press the dispenser lever. If you have water there, you most likely have a frozen line in the door. Changing the water filter often will help but it is not the answer and is can get quite expensive. By the way, Make sure to hold the dispenser lever forward for at least a couple of minutes each time you test for water flow. If you do not get water at the connector at the base of the door after you have disconnected the line, you have a problem with the valve in the back of the refrigerator.

The water line freezes inside the freezer door. There is now an add-on water line heater you can install to thaw the line.

If the ice maker is working, and no water is coming out, the water line may be frozen.  This happened to me yesterday, and I followed the advice on ehow.com.  It worked like a charm! Take a hair dryer, and blow hot air up into the dispenser tube, holding the hair dryer about 8-10 inches away.  After about 5 minutes or so, a tiny chip of ice and a couple of drops may pop out.  Fill up a couple of glasses of water to flush it out, and you should be good!

ive seen this before on this model, what is happening is the water line in the door is freezing and clogging up
the best thing you can doo here is disconnect that tube and try to get it defrosted
i usually suggest to turn the unit off
and open the freezer door let the inside come up to room temp
and drain from the coupler

There should be a water filter inside the water lines to the water spout. This filter could be clogged, or the water lines themselves may still be somewhat frozen and not allowing flow to the dispenser itself.
You can also test the power to the dispensor to make sure it is drawing water. Can you hear the pump trying to pump water to dispenser? The water valve should also be opening. You can test power to the valve that draws in water from the external water lines.
