It realy look like a bad grouping of the union's components.

The door's rotation should ONLY affect the door itself and any element 
that are ON the door.
You need to use nested unions.
Your union *should* look like:

union{// First, the "static" objects
	object {Cabinet rotate Some_Rotation translate Some_position}
	union {// then the door and components.
		object{Door}
		object{Door_handle}//things that must moove with the door
		onject{Door_Decorations}
		rotate Door_opening translate Door_Location
		}
	}

Note: The door and it's handle and decoration can be defines as a 
complete object:
#declare Door_Complete = 
union{object{Door}object{Handle}object{Decorations}}

It's best to declare the door with the AXIS of it's hinges along the Y 
axis. It will be much easier to place it.
