Water dispenser keeps freezing GE Refrigerator
If this is a newer model GE side by side refrigerator, this is not uncommon. what you can do to check to see what is going wrong, remove the toe plate at the bottom front of the unit. Under the freezer door, you will see a white plastic water line, with an inline connector about 4-5" from where the line comes out the bottom of the door. this is normally a blue push-in type connector. On this connector, you will see two white sleeves on either side, push in on this sleeve while pulling the corresponding water line section out of the connector, if you squeeze the sleeve enough, the water line will slip right out. Place a towel on the floor, make sure both ends are on top of towel. Now, breifly actuate your water dispenser trigger, see if water comes out the exposed water line. If water comes out, your entire water dispenser system is OK, but, the water line in the freezer door is frozen, in which case the only way to melt it, is to turn the unit off, open the freezer door, and blow a fan for a few hours, to melt the ice INSIDE the door. You could also buy a new door, but that is very costly.
If no water comes out the exposed water line, then either your water filter is clogged, or you have a bad water valve solenoid
