So first of all there are updates for the ice maker, auger, and drain. They also have a kit for y clips to go on the cooling loop. Furthermore the ice room needs to be sealed with a good silicon. If you have a layer of ice under the bucket the fill line needs to be adjusted. Samsung can walk you through adjusting fill times for larger cubes but if your ice maker is frosted up you need to do all the updates, I wouldn't worry about fill time unless your cubes are too small or the tray is overflowing. Good luck.
