I have a GE Profile Water Cooler. The cold dispenser doesn't dispense water. Any ideas how to fix it? After I turn off the cold switch, after a day it begins to dispense again but when I turn the cold switch on again, after a day it stops. It is almost like a tube freezes. Any suggestions?

It does sound like it is freezing. If you have a manual for it, look to see it there is a thermostat that can be adjusted.
