Parts of a Refrigerator

You won’t find many houses that do not have a refrigerator inside the kitchen. It has been a must-have household appliance for several years now. A residential refrigerator stores your food at the right temperature, in order to stop spoiling and limit harmful bacteria. The cycle of refrigeration starts by transferring the warmth from inside of the appliance to the outside, by relying on the principles of condensation and evaporation.

The primary parts of a refrigerator are. For questions or service call Lane Appliance Repair:


The refrigerator compressor is both a motor and pump, and it’s need for the circulation of refrigerant in the cooling system.
The compressor is a very important part of a refrigerator. You should call on a professional company if the compressor is no longer working.


A refrigerator condenser is attached on the rear exterior wall of the appliance and will help to disperse the heat absorbed within the refrigerator then out in the air.


The refrigerator evaporator is located on the interior of a refrigerator where absorbs warmth contained inside of it, thereby reducing the temperature inside the appliance.

Once the evaporator stops working, it is time to enlist a professional. Do not wait until it is too late.

Expansion Device

Liquified refrigerant is directed through a capillary tube which works as an expansion device to cool the gas inside, transforming it into a liquid.


The refrigerator thermostat exists to regulate the current temperature inside a refrigerator, starting the cooling period when needed.

The thermostat inside of a refrigerator is often prone to breaking. Troubleshoot and hire a technician in CITY for repair the moment a problem happens.

How Does Refrigeration Work?

1. Once the temperature inside a refrigerator goes higher than the set point sensors notify the refrigerator compressor to engage, and the next cooling period starts. The appliance collects the cold liquified refrigerant, condenses and pressurizes the liquid, and raises the temperature, so it can turn into a gas.

2. The compressor directs the heated gas towards the refrigerator condenser coils located on the outside of the unit, at which point it comes into contact with the lower air temperature in the kitchen and transforms back to a liquified state.

3. The cool refrigerant then continues on its journey towards the refrigerator evaporator component, pushing through the many coils on the interior of the refrigerator and top freezer section.

4. The liquid absorbs the heated air from within the appliance, thereby cooling the temperature until it has reached the desired final point.

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

Refrigeration is often used in a number of applications and appliances, including heat pumps, AC units, refrigerators and freezers. By contracting heat from one location and then moving it to somewhere else the cycle of refrigeration helps cooling your house, provides a safe storage space for food that is perishable, and helps with the manufacturing and storage of a number of different products and materials.
