Samsung Refrigerator Control Board Replacement

crwdns2915892:0crwdne2915892:0

This guide shows how to remove and replace the control board in your Samsung refrigerator.

The control board controls the refrigerator's functions. It also has a DC power board built into it. If your refrigerator turns on but doesn't function properly, check the components related to the function first. Replace the control board only after you've verified the other components.

This guide will work for most Samsung Refrigerators . This guide is based on a model RF28R7201SG Refrigerator. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same.
