Sales - Whirlpool W11650662 Refrigerator Defrost Heater Assembly

The Whirlpool W11650662 Refrigerator Defrost Heater Assembly helps prevent frost buildup by melting ice from the evaporator coils during the defrost cycle. This component works by activating at scheduled intervals to gently heat the coils, allowing accumulated frost to melt and drain away, which keeps airflow unobstructed and cooling performance consistent. A properly functioning defrost heater supports energy efficiency and helps maintain a stable internal temperature, reducing strain on the compressor. Replacing a defective heater assembly can resolve issues such as excessive frost, poor cooling, or increased energy consumption. Installing this part ensures the refrigerator operates as intended, supporting overall system reliability and reducing the risk of long-term damage caused by ice accumulation.
