Parts of a Refrigerator

You won’t find many houses that do not have a refrigerator inside the kitchen. It’s been a must-own appliance for many years. A residential refrigerator will store food at the optimal temperature, in order to prevent rotting and limit the growth of harmful bacteria. The cycle of refrigeration starts by distributing the heat from inside of the unit to the outside, using the principles of evaporation and condensation.

The components of a refrigerator are below. For questions or service call Carter’s Appliance Repair:


A refrigerator compressor is a combination of a pump and motor, and it is necessary for the circulation of refrigerant dispensed in the system.
The compressor is an important part of a refrigerator. Homeowners should call a professional service if the compressor is broken.


A condenser is attached on the back exterior wall of the refrigerator and helps to disperse the warmth collected from within the refrigerator then out to the surrounding air.


A evaporator is attached on the inside of the refrigerator where it absorbs the warmth contained inside of it, thereby lowering the temperature inside the refrigerator.

Once an evaporator is not working, it’s time to find a professional. You should not wait until it’s too late.

Expansion Device

Liquified coolant is directed within a capillary tube that acts as an expansion device as it cools the gas, transforming the gas into liquid.


The thermostat exists to regulate the temperature within the refrigerator, starting the cooling cycle when needed.

The thermostat in a refrigerator is prone to malfunction. Troubleshoot and call a technician in Pennsylvania for service the moment a problem happens.

How Does Refrigeration Work?

1. When the temperature in the interior of a refrigerator is above the set point sensors notify the compressor to begin, and then the next cool down begins. The unit draws in the cool liquid refrigerant, condenses and pressurizes the liquid, and increases the temperature, turning it into a gas form.

2. The compressor guides the hot gas towards the condenser coils located on the rear of the unit, where it comes into contact with the lower temperature in the room and returns to a liquified state.

3. The cool liquified gas continues its journey towards the refrigerator evaporator component, pushing through the many coils within the appliance and freezer.

4. The coolant then absorbs the warm air from inside the appliance, cooling the temperature down to the optimal final point.

5. The liquid then will evaporate, and will return back to a gas, and then returns to the refrigerator compressor so it can then continue the cooling cycle.

Refrigeration technology is often found in a lot of applications and household appliances, including heat pumps, air conditioners, refrigerators and freezers. By contracting heat from one place and then distributing it to a different one the cycle of refrigeration contributes in cooling your home, provides a safe environment for food that is perishable, and also helps with manufacturing and storage of a lot of different products and materials.
