Parts of a Refrigerator

There aren’t many homes that don’t have a refrigerator in the kitchen. It has been a standard household appliance for several years. A residential refrigerator stores food and drinks at the right temperature, to stop spoiling and limit the growth of bacteria. The cycle of refrigeration works by moving the heat from the inside of the appliance to the outside, by relying on principles of evaporation and condensation.

The standard parts of your refrigerator are below. For questions or service call Swift Appliance Repair:


The compressor is a combination of a motor and a pump, and it’s responsible for the circulation of refrigerant dispensed in the cooling system.
A compressor is an integral piece of a refrigerator. You should call on a professional company if the compressor is broken.


A condenser is found on the back exterior wall of the refrigerator and will help to emit the warmth collected from inside the refrigerator out to the air.


The refrigerator evaporator is housed on the inside of the refrigerator where absorbs the warmth held within it, effectively lowering the temperature inside the refrigerator.

Right when an evaporator isn’t working, it’s time to find a professional. Don’t wait until it’s too late.

Expansion Device

Liquid coolant is directed through a capillary tube that acts as an expansion device to cool the gas inside, transforming the gas into a liquid.


The thermostat will regulate the current temperature in the interior of the refrigerator, beginning the cooling cycle as it is necessary.

A thermostat in a refrigerator is very prone to issues. Troubleshoot and call a technician in CITY for repair right after an issue happens.

How Does Refrigeration Work?

1. When the temperature within the refrigerator goes higher than the set point sensors signal the refrigerator compressor to engage, and the next cool down starts. The appliance collects the cold liquified refrigerant, condenses and pressurizes the liquid, and increases the temperature, in order to turn it into a gas.

2. The compressor unit pushes the warm gas in the direction of the condenser coils located on the back of the appliance, at which point it comes into contact with the lower temperature in the kitchen and transforms back to a liquid form.

3. The cooled liquified gas then continues on its journey towards the refrigerator evaporator component, pushing through the coils within the refrigerator and freezer compartment.

4. The liquid absorbs the heated air from the interior of the appliance, cooling the temperature until it has reached the desired set point.

5. The liquid then will evaporate, and turns back into a gas state, and returns to the refrigerator compressor in order to continue the cooling cycle.

Refrigeration is often found in many applications and appliances, including heat pumps, AC units, refrigerators and residential freezers. By contracting heat from one area and distributing it to somewhere else the cycle of refrigeration contributes in cooling your home, provides a safe storage space for perishable food, and helps with the manufacturing and storage of a lot of different products and goods.
