Parts of a Refrigerator

You will not find too many houses that do not feature a refrigerator inside the kitchen. It has been a must-have kitchen appliance for several years. A residential refrigerator is able to store your food at the best temperature, in order to prevent spoiling and stop harmful bacteria. The process of refrigeration starts by transferring the warmth from the inside of the refrigerator to the exterior, using principles of evaporation and condensation.

The standard parts of your refrigerator are. For questions or service in Chula Vista call Premiere Appliance Repair:


The refrigerator compressor is both a pump and motor, and it is necessary for the circulation of refrigerant throughout the system. The compressor is an important part of a refrigerator. Homeowners should call on an appliance repair company if the compressor is no longer working. You find a replace refrigerator compressor from The Appliance Depot.


A refrigerator condenser is found on the rear exterior wall of the refrigerator and is there to release the warmth collected from within the refrigerator out to the surrounding air.


The refrigerator evaporator is housed in the interior of a refrigerator where it absorbs warmth trapped inside of it, effectively lowering the interior temperature.

The moment the evaporator is not working, it is time to call a professional appliance repair service. Don’t wait until it’s too late.

Expansion Device

Liquid coolant is directed within a capillary tube which serves as an expansion tool as it cools the gas, transforming it into a liquid.


The thermostat helps regulate the current temperature throughout the refrigerator, engaging the cooling period as necessary.

A thermostat in a refrigerator is prone to breaking. Troubleshoot and hire a professional appliance repairman in for repair the moment a problem occurs.

How Does Refrigeration Work?

1. Once the temperature in the interior of the refrigerator goes higher than the set point sensors alert the compressor to engage, and then the cooling cycle starts. The unit collects the cold liquified refrigerant, condenses and pressurizes the refrigerant, and raises the temperature, so it can turn into a gas form.
2. The compressor unit pushes the hot gas towards the refrigerator condenser coils located on the outside of the refrigerator, where it comes in contact with warmer temperature in the room and returns to a liquified form.
3. The cool liquid continues its trip to the evaporator component, pushing through the many coils within the appliance and freezer.
4. The liquid then absorbs the hot air from within the refrigerator, thereby reducing the temperature back to the desired final point.
5. The refrigerant then will evaporate, and turns back to a gas state, and returns to the compressor in order to then continue the cycle.

Refrigeration technology is used in a lot of applications and large appliances, including heat pumps, AC units, refrigerators and residential freezers. By contracting heat from one area and then transferring it to somewhere else the cycle of refrigeration contributes in cooling your home, provides a optimal environment for food that is perishable, and helps with manufacturing and storage of many different everyday products and materials.
