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.
Unit turns off. When reboot it come up temps come on and settle 8 deg freezer, 36 in the refrigerator. Last @ 12 hr. when I wake up temps are change thawing.
Based on the information it sounds like the unit is sticking in the defrost and causing the unit to warm up. For this issue the most likely cause would be a faulty control board DA41-00128D.
My freezer works fine but refridge dosent keep cold. Food goes bad is it the temperature sensor or what?
You will want to check to make sure that the evaporator coil in the refrigerator is not impacted with ice and causing the unit to not cool properly. If it is then you will want to Test the sensors DA47-00095E and see if they are around 5.5K at room temperature. If so, the sensors are working and you will need to replace the main control board on the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
