The RS20CCMS does have a design flaw, the Samsung Engineers say not but it does as does the RS21, this is a common fault and we have experienced it noe on several occasions. The only thing I can suggest is to write to Watchdog as I have done so, the more people that write in about the RS20CCMS the better and then perhaps something can be done for the poor customers that just keep on paying those Samsung Engineers. For the RS21 customers Samsung will extend the warranty for an extra 5 years, we want this for the RS20CCMS as the problem is exactly the same. Last November 2007 the temp went up in fridge then freezer with the temperature unit flashing, told by an Engineer to defrost for 48 hours to see if problem rectifies did this and it was fine for about 3 weeks then the problem arose again, I lost two lots of food and it was only a few weeks until Christmas when it happened for the second time and everyone was coming to me for Christmas. Got the part replaced and the Engineer explained it was bad luck and not a design flaw, so if it is not a design flaw how come so many people have experienced the same disaster with their RS20 Fridge Freezer, another ten months later and I now have the same problem again, I could scream, Samsung won't get back to me so I guess I have to shell out another fee for the Engineer and the part and wait until it happens again, I am inclined to buy a simple frosty freezer with a reliable make which I will be investigating. Hope this helps, all I can say is call Watchdog or Email them.
