Customer Questions and Answers for Refrigerator Main Control Board Assembly by Samsung

Hello Kare. Yes, it could be the board. But first you need to test the bi metal and heater in the evaporator be fore replacing the board. 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

Hello Karen. You will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Marta, The main control board will be located at the back of the unit and behind the cover at the bottom of the unit. On the right side will be a plastic box that would house the control board.

Robin, You will want to check the frost pattern on the evaporator coils. If there is very little frost pattern or non at all with the compressor running then this would be a sealed system issue and would require service.

Hello Nick, If there is good air flow inside the unit, I would check the pressures in the sealed system since there should be a good frost pattern with the compressor running.

Hello ABHIJITH. Sorry this is an international model and we do not offer any parts for this unit.

Mary-Ann, Yes, that part has been discontinued by the manufacturer. The manufacturer no longer sells the part. We can no longer get it from any of our suppliers and there is no substitute for the part available to us, and we don’t know of any other source for the part. You may want to try contacting local parts dealers, one of them might still have it in stock. Enter your part number in a search engine, a smaller company might have it. Try eBay, Amazon or similar sites, search by using the manufacturers part number. Try a used appliance store, sometimes they have the same model or a useable part for your machine. Lastly, Contact refurbishing companies, especially for circuit boards: www.circuitboardmedics.com, www.corecentricsolutions.com, to see if they have a program to remanufacture your control board. Thanks,

Kenney, There is a thermistor on the evaporator coil that you will want to test resistance of. The resistance should be 5K ohms at 77 degrees and if it is not correct then would need to replace the thermistor. If this checks ok then the main control board would be the likely issue.

David, You will want to check to make sure that the fan in the freezer is working. If it is not then test to see if there is 12 vdc getting to the fan motor. If there is then the fan motor will be faulty and needs to be replaced.

Bob, With the display showing only partial lines then this would most likely be a display board causing this. You will want to check to see if the compressor is running. If it is not then it would be more likely that the issue is with the inverter board.
