Well, I changed the mother board after two weeks both freezer and fridge had to be manually defrosted again. What now?
Answer Hello Rod. Test and see if the heaters are bad in both evaporators. If so, you will need to have them replaced. However, it takes an HVAC tech to do a sealed system repair. 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
I had a technician look at my refrigerator, I know one item was the main PCB board or panel, they want to charge a arm and a leg so they don't really tell you the part, but I know for sure one part was the PCB main board, I was able to get the part names, so I called Samsung, they gave me the main board part number which I replaced, and the other part Samsung sent me was the part number DA41-00264A, its the display in the door, would that with the main board not keep the refrigerator cold, because I replaced the main board and the display panel and the refrigerator still isn't cooling, staying at 57 to 59, I could of swore one part you had to get to from the inside of the refrigerator, so I think the display panel wasn't the part I needed to replace, the main board for sure but what part inside the refrigerator could it be
You would be correct in regards to the display board not allowing the refrigerator side to work. In most cases when the refrigerator side is not working, the unit is not defrosting properly and it would be a defrost sensor that has failed or the main control board. You will want to check the defrost sensor.
