Sanjeev for Model Number Samsung rb1855sw I start my refrigerator, its start fine. Freezer and upper part temp reach to -8 and 32 respectively. Its shutdown after that reaches that point. It’s not restart after temperature change to high. When I restart the refrigerator its start working again and Stop after reach the same point. Temperature change high on display after restart. As per you guy I replace the main board. After that I have same issue. Please let me know what the next step is.
Answer Hello Sanjeev. You will want to check the temp sensors in the unit and make sure they are reading properly. If so, then it sounds like the main control board on the unit is bad and will need to be replaced 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 Read More...
