The evaporator fan is a crucial component of a Kenmore freezer, responsible for maintaining a consistent temperature inside the unit. Understanding its role and regular testing are essential for ensuring optimal performance and preventing potential issues.
Understanding the Role of the Evaporator Fan in a Kenmore Freezer
The evaporator fan works in conjunction with the evaporator coils to circulate cold air throughout the freezer. Its primary function is to draw air over the evaporator coils, which absorb heat from inside the freezer, and distribute the cooled air back into the freezer compartment.
But let’s dive deeper into how the evaporator fan actually accomplishes this task. As the fan spins, it creates a suction effect that pulls air from the freezer compartment towards the evaporator coils. This air, which may contain moisture and heat, is then forced over the coils, where the refrigerant inside them absorbs the heat and cools the air. Once the air is cooled, the fan propels it back into the freezer, ensuring a consistent and even temperature throughout.
The Function of the Evaporator Fan
By constantly circulating the cold air, the evaporator fan helps maintain a steady temperature, preventing hot spots and ensuring even cooling throughout the freezer. This is crucial for preserving the quality and freshness of the stored food items.
