Metal Sheath for Refrigerator Heater
The Defrost Heater serves as an OEM replacement part vital for maintaining the efficiency of Samsung refrigerators. It is designed to clear ice from the evaporator fins during the automatic defrost cycle, thereby preventing the cooling element from freezing over. A metal sheath surrounds the heater, offering protection to the heating element and ensuring even heat distribution throughout the unit.
Collaborating with the defrost timer, the heater activates intermittently to fulfill its purpose. To assess its performance, one can measure its resistance, which should read 120 Ohms. Signs such as ice accumulation on the cooling element or inadequate cooling may suggest a malfunctioning or deteriorated defrost heater.
