Thank you all very much for this super helpful info. Samsung refuse to give out this info
I am happy to say this also works for model SRS610HDSS, you need to hold freezer temp button and power cool to enter. I have found very little info on this model.
Is anybody able to say what mode 2,3 and 4 adjust. I assume probably defrost sensors offset and or rear fan offset. 0 is freezer and 1 is fridge, what is 2,3 and 4 adjust?
