Whirlpool WPW10486820 Defrost Heater

The Whirlpool WPW10486820 Defrost Heater is an essential component of your refrigerator's defrost system. It's basically a heating element that runs on electricity to periodically melt frost accumulation inside the freezer section. During the defrost cycle, a timer activates the heater, which produces heat to melt the collected ice. This melted ice then drains away via a tiny channel, avoiding frost from obstructing airflow and limiting the refrigerator's capacity to maintain correct temperatures. Excessive frost buildup, decreased cooling effectiveness, and even food damage might result from a malfunctioning defrost heater. Replacing a faulty defrost heater with the Whirlpool WPW10486820 ensures that your refrigerator's defrost system runs smoothly, ensuring ideal temperature control and reducing food deterioration.
