Experiencing inconsistent cooling or unusual frost build-up in your refrigerator might indicate a problem with the evaporator assembly. The Samsung evaporator assembly (DA96-00660N) is an important component for optimal performance in maintaining the internal temperature of your 3-door French door refrigerator. If your appliance is not cooling well or there's frost accumulation, this could be the part you need. Be sure to verify your device's model number for compatibility before purchasing.
