Automatic defrost is a feature found in many modern refrigerators and freezers that helps prevent the buildup of ice. This system periodically warms the cooling elements to melt any frost that has formed, allowing the water to drain away. This process ensures that the appliance operates efficiently and maintains optimal temperatures for food storage. The automatic defrost cycle typically runs at regular intervals, depending on the model and usage. This feature eliminates the need for manual defrosting, saving time and effort for users. Overall, it enhances the convenience and performance of refrigeration appliances.
