Watched several on-line repair videos. Saw ice on the water tank in the fridge side. Thawed it with hair dryer, and the tank had cracked. Ordered a new water tank, and replaced it and thawed the dispenser area on the freezer door inside and out. Took 30 minutes alternating inside and out then the line melted clear and worked fine. When routing the tank water lines you'll need to guide them past the solenoid from the back underneath, and there is a slot for the water line that runs to the door in the plastic flap that runs underneath the fridge which the line must run through or it will seem too short to make the connection. Also open both door when working on the water line connections in from. It is very tight in back connecting to the valve you'll get cut easily.
