I have a samsung side by side fridge.freezer and the freezer is not cooling. I have taken off the back of the freezer to see the coils and it is all iced over all the way up to the fan. Could this be the temperature sensor? If so, where do i find it? I also see your site saying evaporator assembly.
The issue that you are having could be caused by a faulty defrost sensor. You will want to test the defrost sensor which is located on the top of the evaporator coil and to check you would do a resistance check. The other thing you would want to do is check the heater assembly. Make sure that it has continuity.
Can not reset my temperture for some odd reason the freezer and refrig temp went up negative numbers. I unplug the unit then it went back to normal the minutes later both started to rise.what can I do?
The most common cause for the temperatures to not reset would be caused by a faulty display board. If when pressing the controls up the temperature decreases then the display board is faulty and would need to be replaced. You will also want to test the sensors in the unit to make sure that they are good.
