How do I dismantle my american fridge door to re-attach the water pipe?

I recently moved house and the doors where taken off my american fridge freezer to get it into my new house. Unfortunatly this pulled the water pipe from its connection point inside the fridge door. I have tried to dismantle the door from the front where the water and ice comes from but can only get so far. Can anybody tell me which way is best or point me to a web site that would have instructions on how to reattach the pipe.

Cheers
