How to Change the Water Line Inside the Refrigerator Door

New refrigerators often have a water dispenser installed in the door. The dispenser requires a water line that runs from under the kitchen sink to the door. The water lines are usually made of thin copper tubing and connect to the back of the fridge with a compression nut. A plastic water line runs inside of the refrigerator door that may need replacing if it starts to leak. This requires separating the door.
