Understanding Your Refrigerator
Refrigerators are complex appliances designed to keep food and beverages cold and fresh. They operate through a series of components that work together to regulate temperature. Understanding how these parts function can help you identify problems more easily.
The Key Components of a Refrigerator
Compressor: Often referred to as the “heart” of the fridge, the compressor pumps refrigerant through the system. If it fails, the fridge may not cool properly.
Condensing Coils: These coils expel heat from the refrigerant. If they are dirty or blocked, the fridge can’t maintain the right temperature.
Evaporator Coils: These coils absorb heat from inside the fridge. Issues here can lead to frost build-up and insufficient cooling.
Thermostat: The thermostat measures the temperature inside the fridge and regulates the compressor’s operation.
Fan: The fan circulates cold air throughout the appliance. If the fan malfunctions, you can experience uneven cooling.
Defrost Timer and Heater: These components prevent frost build-up. If they fail, ice can accumulate and block airflow.
