DA47-00318E - Samsung Refrigerator Defrost Heater

This Samsung Refrigerator Defrost Heater (DA47-00318E) is a genuine Samsung product, suitable for Samsung refrigerators. This defrost heater, also known as a "heater metal sheath," plays a critical role by warming the refrigerator's evaporator coil to prevent frost build-up. Over time, a malfunctioning defrost heater could lead to an excessive build-up of frost in your refrigerator's freezer, which can reduce cooling efficiency and increase energy consumption. Symptoms that may indicate it's time to replace this part include a freezer that is overfrosting or not defrosting properly, and a decrease in the overall cooling efficiency of your appliance. Before purchasing, kindly verify your refrigerator's model number to ensure compatibility with the DA47-00318E defrost heater.
