It operates by heating the evaporator regularly to melt any ice which has formed. This causes it to evaporate into the air. Automatic Defrost The automatic defrost function that is found on freezers that are frost-free is designed to prevent the formation of ice within the freezing compartment. It works by periodically turning the freezer on and melting the frozen ice that would otherwise built up over time. The melted ice is then emitted into the air. This is a much easier method to defrost your freezer than manually. Frost Free fridges and freezers typically have a defrost heater located in the evaporator coils, behind the fan, a pan to capture and evaporate the water that is evaporated from the melting ice, which is later transformed back into liquid using the heater for defrost and an alarm clock that will shut off the compressor and turn on the heating element normally between once and 4 times a day for a period of 15 and 30 minutes. The timer also features an defrost thermostat to stop the freezer temperature from increasing too significantly during the process of defrost. While this is more convenient and reduces maintenance costs, it requires electrical power to run the defrost system. It can take a long time for a defrost process to be completed. If the defrost device malfunctions or the temperature gets excessively during a defrost process taking place, it could disrupt the cooling process and cause damage to the refrigeration components. Manual defrosting refrigerators remain used in some companies. This is especially the case in places where frost-free refrigerators with automatic technology aren't available. They are generally less expensive and more easy to maintain, but they may have a shorter lifespan tha
