Samsung RS21DCSV

Have owned this model for about 3 years, water dispenser paddle support bracket broke during warranty period and was reaired using a Modification kit according to the service engineer who did the repair. This repair has now broken off and the paddle is left flapping in the breeze. Water can still be dispensed but it’s fiddly and sometimes messy!. My question is, is their any way of replacing the housing that contains the control panel and dispenser paddles or does the whole door have to be replaced. Any advice will be greatly appreciated.
