How can I get to the water dispenser without taking apart the door?

How can I get to the water dispenser controls without taking apart the door on a GE Side by Side? The controls are on the left side(freezer) as you look at it. It is a 25 cubic foot. I replaced the water supply valve that takes water to the ice maker and water dispenser. The water dispenser was slow at first but worked, now it does not. The ice maker works great!
