We did not have this problem for doors/drawers to be removed. However, here is some input which may be useful:
1. If delivery/installation included with your order, they will take care of removal/assembly of doors/drawers and the kitchen access (and Main entrance) door removal/assembly as needed. However, ensure that dimensions (depth of the refrigerator) after removal of both refrigerator & kitchen access doors still allow for the refrigerator to be moved inside the kitchen.
2. If delivery/installation not included with your order, you need to find dimensions as explained above. As I recall, in one of the vidoes provided by Samsung, it explains how lower two drawers use clip on mechanism for easy removal and put it back. For the top two doors, as I recall, they are easy to remove from the top hinges. For all the electric/water connections on either side they are male/female end connectors which are easy to remove and connect as well.
Hope this helps! Thanks!!
