Parts of a Refrigerator

You won’t find many houses that do not feature a refrigerator inside the kitchen. It has been a must-own household appliance for several years. A household refrigerator will store your food and drinks at the right temperature, to stop spoiling and limit harmful bacteria. The concept of refrigeration works by moving the warmth from the inside of the refrigerator to the outside, by relying on principles of evaporation and condensation.

The main components of a refrigerator are. For questions or service call Stone Appliance Repair:


The compressor is a combination of a pump and a motor, and it’s responsible for circulation of refrigerant in the cooling system.
The compressor is a very important piece of a refrigerator. Homeowners should hire a professional company if the compressor is broken.


A condenser is found on the back outside panel of the refrigerator and will help to disperse the heat absorbed inside the refrigerator then out to the surrounding air.


The refrigerator evaporator is installed in the interior of the refrigerator where absorbs warmth held inside of it, effectively lowering the temperature inside the unit.

The moment an evaporator stops working, it is time to call a professional. Do not wait until it is too late.

Expansion Device

Liquid coolant is directed through a capillary tube that acts as an expansion device to cool the gas inside, thereby turning the gas back into liquid.


A refrigerator thermostat regulates the current temperature in the interior of a refrigerator, engaging a new cooling cycle as appropriate.

A thermostat in a refrigerator is often prone to issues. Troubleshoot and hire a contractor in CITY for service right after a problem happens.

How Does Refrigeration Work?

1. Once the temperature inside a refrigerator is higher than the set point sensors signal the refrigerator compressor to start, and then the cooling cycle starts. The appliance attracts the cool liquid refrigerant, condenses and pressurizes the refrigerant, and increases the temperature, in order to turn it into a gas form.

2. The compressor unit guides the heated gas towards the refrigerator condenser coils located on the exterior of the refrigerator, at which point it comes in contact with the lower temperature in the home and transforms back to a liquid form.

3. The cooled liquid then continues its journey towards the refrigerator evaporator, pushing through the many coils within the appliance and top freezer.

4. The coolant then absorbs the warm air from within the appliance, lowering the temperature until it has reached the desired final point.

5. The refrigerant then evaporates, and will return back into a gas state, and then returns to the compressor so it can continue the cooling cycle.

Refrigeration is used in a lot of applications and household appliances, this includes heat pumps, air conditioners, refrigerators and freezers. By removing heat from a single location and distributing it to a different one the continuous cycle of refrigeration contributes in cooling your house, creates a optimal environment for food that is perishable, and helps with the manufacturing and storage of several different products and materials.
