The water line leading to the door is cracked and leaking all over the floor. How do we replace that line?
If the water line that is broken is the line that is actually in the door then the door would need to be replaced. If the water line is just the one that goes from the back of the unit to the door then you will need to replace the water tank in the unit. To replace you will pull the unit out and shut off the water supply. Remove the lower cover and disconnect the tube that leads up into the refrigerator compartment. Then remove the kickplate on the front of the unit and disconnect the water line at the door. Open the refrigerator door and remove the lower crisper drawers and remove the water tank and insert the new one. Pay close attention to how the water tube is routed for the door.
