I have a Samsung RS265TDBP/XAA that the refrigerator is below freezing. I have replaced the temperature sensor. I checked the ohms in both the old and new sensors and they read correct at 32 F.
What else could cause this. Changing the temperature setting does not have any effect. Recently I replaced the temperature sensor and fan in the freezer section. It was working fine after that.
I am a little reluctant to replace the main power control board and find out that it does not correct the problem since if i install it to see if it works i cannot return it. There is also another power control board in this refrigerator. Any ideas on what the problem may be and advice on if it is worth trying the main power control board or the power control board.
I am about to never buy another Samsung product. I have had problems with stove, washer, dryer and TV and refrigerator from them all shortly after warranty ran out. It seems that appliances should last longer than 1 or 2 years.
