Parts of a Refrigerator

You won’t find too many homes that don’t have a refrigerator in the kitchen. It’s been a standard household appliance for many years. A refrigerator will store food and drinks at the optimal temperature, in order to reduce spoilage and slow down harmful bacteria. The process of refrigeration works by transferring the heat from inside of the refrigerator to the outside, by using principles of condensation and evaporation.

The components of your refrigerator are below. For questions or service call Nifty Naperville Appliance Repair:


A compressor is both a pump and a motor, and it’s necessary for circulation of refrigerant dispersed in the cooling system.
A compressor is an integral part of a refrigerator. You should enlist a professional company if the compressor isn’t working.


A condenser is located on the rear exterior wall of the refrigerator and is there to release the warmth absorbed from inside the refrigerator out into the surrounding air.


A evaporator is stored on the inside of the refrigerator where absorbs the warmth held inside of it, thereby lowering the interior temperature.

Right when the evaporator is not working, it’s time to call a professional. You should not wait too long.

Expansion Device

Liquified refrigerant is transported through a capillary tube which works as an expansion device as it cools the gas inside, turning the gas back into liquid.


The refrigerator thermostat exists to regulate the current temperature in the interior of the refrigerator, engaging a new cooling cycle as necessary.

The thermostat in a refrigerator is prone to issues. Troubleshoot and call a technician in Naperville for repair right when a problem happens.

How Does Refrigeration Work?

1. The moment the temperature inside a refrigerator goes higher than the set point sensors signal the compressor to start, and then the cool down starts. The appliance draws in the cold liquid refrigerant, then condenses and pressurizes it, and increases the temperature, so it can turn into a gas.

2. The compressor unit pushes the hot gas in the direction of the refrigerator condenser coils located on the back of the unit, where it comes into contact with the lower temperature in the kitchen and reverts back to a liquid form.

3. The cool liquid then continues on its trip to the evaporator component, pushing through the coils on the interior of the refrigerator and freezer section.

4. The coolant absorbs the warm air from within the refrigerator, lowering the temperature back to the correct set point.

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

Refrigeration is often found in a lot of applications and household appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By contracting heat from a single area and then transferring it to another the continuous cycle of refrigeration aids in cooling your home, provides a optimal space for perishable food, and helps with manufacturing and storage of a number of different everyday products and materials.
