Parts of a Refrigerator

You won’t find too many homes that do not have a refrigerator inside the kitchen. It’s been a must-have kitchen appliance for many years. A residential refrigerator stores your food and drinks at the best temperature, to eliminate spoilage and limit harmful bacteria. The concept of refrigeration starts by distributing the heat from the inside of the unit to the exterior, by using the principles of condensation and evaporation.

The standard components of a refrigerator are below. For questions or service call Pearson Appliance Repair:


A refrigerator compressor is a combo of a pump and motor, and it is responsible for circulation of refrigerant throughout the cooling system.
A compressor is an important part of a refrigerator. Homeowners should call a professional company if the compressor isn’t working.


The condenser is found on the rear exterior wall of the appliance and will help to release the heat built-up from within the refrigerator then out into the air.


A refrigerator evaporator is stored on the interior of the refrigerator where it absorbs heat trapped within it, thereby reducing the interior temperature.

Once the evaporator isn’t working, it’s time to hire a professional. Don’t wait until it’s too late.

Expansion Device

Liquid refrigerant is transferred through a capillary tube that serves as an expansion device to cool the gas inside, transforming the gas into a liquid.


A thermostat helps regulate the temperature in the interior of a refrigerator, starting the cooling period as required.

The thermostat inside of a refrigerator is often prone to malfunction. Troubleshoot and call a technician in CITY for service the moment an issue happens.

How Does Refrigeration Work?

1. When the temperature in the interior of a refrigerator goes higher than the set point sensors alert the refrigerator compressor to start, and the next cool down starts. The unit draws in the cold liquified refrigerant, condenses and pressurizes the refrigerant, and increases the temperature, turning it into a gas form.

2. The refrigerator compressor unit pushes the hot gas towards the refrigerator condenser coils located on the outside of the unit, where it comes into contact with the lower air temperature in the room and returns to a liquid state.

3. The cooled refrigerant continues its trip towards the evaporator, traveling through the many coils within the refrigerator and freezer compartment.

4. The liquid absorbs the hot air from inside the refrigerator, cooling the temperature until it has reached the best final point.

5. The refrigerant then evaporates, and turns back to a gas form, and then returns to the refrigerator compressor unit so it can then continue the cooling cycle.

Refrigeration technology is found in several applications and household appliances, including heat pumps, AC units, refrigerators and freezers. By removing heat from a single area and then distributing it to another the cycle of refrigeration contributes in cooling a house, provides a optimal space for perishable food, and also helps with manufacturing and storage of many different everyday products and materials.
