My frigidaire refrigerator water dispenser, disperses water on its on when not in use. What can cause this?

I'll start with a question to you. Is it dispensing water on its own, out of the water disperser, only when you hear the Ice maker valve function or is it constant? Mine would seep water out of the dispenser after I poured a glass of water and or the ice maker would use water. Not much, a few drops at first but it kept getting worse. I found out that there was a lime build-up in the dual solenoid water valve. To get to this valve, gain access to the back bottom of your fridge. Shut the water supply and pull the power cord. Remove the cardboard cover, disconnect all tubes connected to the valve unit and pull the electric plugs. Remove the 2 metal screws holding the valve assembly and pull it straight out (the other end of the valve assy is held by a key hole type slot). Now that you have the valves out, blow in the supply inlet and you should see if one of these valve is not making a perfect seal. Once you have this figured out, it is time to fix it. The valve are a sealed unit and opening them would wreck them but you don't need to take them apart. A replacement valve assy will set you back a $100 but there should be no need for a new valve. Not much in there can break. Just pour a little CLR or Lime out in the inlet and use a small tooth pick to push and release the valve plunger in and out. Put as much liquid as you can fit in and let it stand for a few hours until the calcium has dissolved. Work the plunger again to free the big stuff, rinse it all and blow to confirm that the seal is now perfect. Put it back together (easy, all the lines are colour coded. Make sure you don't have a leak and push your fridge back in its spot. Voilà! P.S While you are in there, you may want to vacuum the condenser and all the dust you will see. You should have no shortage of dust... :)
