Parts of a Refrigerator

There are not too many homes that don’t have a refrigerator inside the kitchen. It’s been a standard appliance for many years. A residential refrigerator stores food and drinks at the optimal temperature, to eliminate spoiling and limit the growth of bacteria. The concept of refrigeration works by distributing the heat from the inside of the unit to the outside, by relying on the principles of condensation and evaporation.

The standard parts of a refrigerator are. For questions or service call Same-Day Skokie Appliance Repair:


A compressor is both a motor and pump, and it is necessary for the circulation of refrigerant in the cooling system.
A compressor is an important part of a refrigerator. You should call on a professional service if the compressor is broken.


The condenser is attached on the rear outside wall of the refrigerator and helps to release the heat collected from inside the refrigerator then out to the surrounding air.


A evaporator is installed in the interior of a refrigerator where it absorbs heat trapped inside of it, effectively reducing the interior temperature.

Right when the evaporator stops working, it’s time to enlist a professional. You should not wait until it’s too late.

Expansion Device

Liquified refrigerant is transported within a capillary tube that serves as an expansion tool as it cools the gas, transforming it back into liquid.


The thermostat regulates the current temperature within a refrigerator, starting a new cooling cycle as needed.

A thermostat inside of a refrigerator is prone to issues. Troubleshoot and call a contractor in Skokie for repair right after a problem happens.

How Does Refrigeration Work?

1. The moment the temperature inside a refrigerator rises above the set point sensors signal the compressor to start, and then the next cooling period begins. The unit attracts the cold liquid refrigerant, pressurizes and condenses the refrigerant, and raises the temperature, so it can turn into a gas.

2. The refrigerator compressor unit pushes the heated gas towards the condenser coils on the rear of the refrigerator, at which point it comes into contact with warmer temperature in the home and returns to a liquid form.

3. The cooled liquified gas continues its trip towards the evaporator component, making its way through the many coils within the refrigerator and top freezer compartment.

4. The liquid absorbs the hot air from within the appliance, thereby returning the temperature until it has reached the best final point.

5. The liquid then evaporates, and will return back into a gas, and then returns to the refrigerator compressor unit in order to then continue the cycle.

Refrigeration technology is used in a number of applications and large appliances, including heat pumps, AC units, refrigerators and residential freezers. By removing heat from a single area and distributing it to a different one the continuous cycle of refrigeration contributes in cooling your house, creates a perfect environment for perishable food, and helps with manufacturing and storage of many different everyday products and materials.
