My water dispenser is not working. The line is frozen. We unpluged the water line from the back of the fridge, let it sit at room temperature and had a warm hair dryer on the freezer door. The problem fixed itself. Water was working! Until the next day... Why would it keep freezing up?

It may very well be frozen. Some of those fridges have problems with the line freezing because of the way the line runs. The one way to tell would be to empty fridge, unplug, and let sit to thaw. Opening freezer/fridge doors will shorten the process. You can Google your exact model number also, and find out how your lines run and use a hair dryer on that location.
The paddle that you push the glass against to dispense water activates a microswitch. Sometimes this switch can break off it's mount and drop away from it's intended position. The microswitch operates a solenoid valve near where the water line enters the back of the fridge. Then there's the wiring in between them. The water line doesn't go through the freezer. It runs through the refrigerator in a coil of tubing then into the door of the dispenser. Check the paddle switch, the water solenoid and the wiring and you'll find the reason it doesn't work
Your freezer is what actually cools the refrigerator. The cool air enters from that spot on the top left of the freezer. Make sure that isn't blocked. It's sounds like the thermostat that controls the air flow from the freezer to the refrigerator isn't working or the air flow control device is stuck.
Either way if you can, unload and unplug the unit. This will do to things. First it will reset the circuits that control everything and secondly if the air flow control is frozen thawing out the refrigerator and freezer may free it up.
Pull the fridge out and look behind it. You're looking for the water line that could possibly have valve shutoff. If not, follow the line back to the source. Could be tapped under the sink, could go anywhere. You are attempting to shut off water to the fridge without shutting water off to entire home. Worst case scenario is if you can't locate the fridge shutoff and you can't get it fixed today and you don't want to leave the freezer door open, locate the main water shutoff for the house and shut it off over night. Hope this helps.
When you push in the water dispenser do you hear two clicks? The first click is the switch in the front. The second click is the solenoid in the back. The solenoid has to open to let water through. If you don't hear that second click then it is most likely the solenoid.
If you remove the grill below the fridge doors you will find a plastic line and a coupling. disconnect the coupling. Push the dispenser arm in and see if water comes out. If it does then you have a frozen water line in the freezer door. Most likely it is frozen right below the ice cube dispenser door as it sometimes leaks out cold air if it does not shut properly. You can use a heat gun or hair dryer to thaw the line. Be careful not to melt any of the components.
If you do not get water out of the line at the coupling then it may be frozen in the fridge cooling coil. This is rare and usually only happens if you run your fridge on a very cold setting.
I have a gsl25jfpe bs ge regrigerator and the baffle motor that controls air flow from the freezer to the refrigerator is out. This had been causing everthing in the fridge to freeze and cause the water to stop working due to water freezing in the storage tank. The baffle is in the back top of the fridge covered with a plastic cover. Remove plastic cover to check baffle function.
When the filter freezes up, the outside casing may have cracked and will leak water when you dispense water through the door. You will need to have the filter replaced and that should take care of the problem. But the filter should never have frozen in the 1st place. You will need to call a qualified LG technician to see what's going on inside the refrigerator.
