Not sure about what you are saying is the problem, Do not know thw particular model. but is similar to the samsung model I have. Do not know why you changed all those parts. I did not know it was possible to turn off completely the freezer, why get a fridge/freezer. turn off the ice making yes. Which defrost did you replace, probably the one in fridge, as that is the one that tends to go. probably one in freezer section as well, same reason as in fridge. As you are getting ice, and hot(I assume outside) compressor etc working, SO besides the ice in freezer, what is the problem, and why change all those parts?
