DA47-00244W Samsung Refrigerator Metal Heater Sheath

Refrigerator Metal Heater Sheath. The Defrost Heater is an OEM replacement part essential for the optimal performance of your Samsung refrigerator. It is engineered to defrost the evaporator fins during the refrigerator's automatic defrost cycle, helping to prevent the cooling element from icing over. The heater is encased in a metal sheath which protects the heating element and promotes uniform heat distribution across the appliance.

The defrost heater works together with the defrost timer, activating the heating element periodically. To verify its functionality, the heater can be checked for a resistance of 120 Ohms. If you notice that the cooling element in your refrigerator is icing up or the appliance is not cooling efficiently, it may indicate that the defrost heater is worn or damaged.
