Exploring the Different Components of a Refrigerator and How They Work?

To effectively troubleshoot a refrigerator, it’s important to understand its different components and their functions. By familiarizing yourself with these parts, you can quickly identify and predict any potential issues your refrigerator may be experiencing.

The Compressor

The compressor serves as the heart of the refrigerator, responsible for pumping the coolant throughout the system. It initiates the refrigeration process, regulates pressure and temperature, and ensures optimal functionality. Typically located at the base of the refrigerator, the compressor is crucial for proper cooling.

Condenser Coils

These coils, located at the back of the refrigerator, play a vital role in the refrigeration cycle. They help condense the refrigerant from a vapor to a liquid state as it passes through them. This condensation process generates heat, which can be felt emanating from the back of the refrigerator. Regular cleaning and brushing of the condenser coils every 2 to 3 months is recommended for efficient operation.

Expansion Device

As the liquid refrigerant exits the condenser coils, it reaches the expansion device. This component is responsible for converting the liquid refrigerant back into vapor form. Its main function is to control the release of pressure within the refrigeration system, ensuring proper functioning.

Evaporator Coils

The evaporator coils are located behind the freezer and are central to the cooling process. As the liquid coolant flows through these coils, it absorbs heat from the surrounding environment, typically the food compartment. This heat absorption facilitates the cooling of the refrigerator, maintaining the desired temperature.

Problem 3: Fixing a Malfunctioning Compressor in Your Refrigerator

The compressor is a vital component responsible for cycling refrigeration within the refrigerator. Short cycling, where the compressor frequently turns on and off, may indicate dirty condenser coils or fan blades.Clean the condenser coils and fan blades to prevent frequent cycling and increased energy consumption.Consider using lightweight filter material or old pantyhose to trap debris and prevent dust buildup.A refrigerator running too frequently may be caused by setting the temperature too low.Adjust the temperature settings to an appropriate level to avoid excessive cycling.Ensure proper installation of the refrigerator in a location with suitable temperatures and ventilation. Keep the refrigerator doors closed as much as possible to maintain stable temperatures and reduce strain on the compressor.Test the door seal for any breaks or faults that may cause air leakage.Defrost the freezer and clean the condenser coils to optimize heat dissipation and cooling efficiency.Test the continuity of various components, such as the condenser fan, overload protector, compressor relay, and motor, using a multimeter.Check the outlet voltage to ensure it falls within the appropriate range for the refrigerator.

Problem 4: Frost or ice buildup in refrigerators 

Frost or ice buildup in refrigerators can occur when the freezer door doesn’t seal properly or when there are damaged gaskets or hinges. Warm air enters the freezer, causing condensation and ice formation. To fix this, check for gaps or leaks in the door and replace or adjust it as needed. Replace damaged gaskets and lubricate hinges if necessary. Avoid leaving the freezer door open for too long and ensure it closes tightly. Clean clogged defrost drains and consider adding a drain heater if needed. Older freezers may be more prone to frost buildup, so check for cracked door seals or faulty defrost sensors.

Problem 5: Refrigerator Light Issues when only light is working

When only the light in your refrigerator is working, there are a few things you can check. 

  • Check if there is a general power outage or if the circuit breaker has tripped. Also, ensure that the fridge is properly plugged in.
