Parts of a Refrigerator

There are not too many homes that do not feature a refrigerator in the kitchen. It has been a standard kitchen appliance for several years now. A refrigerator will store your food at the best temperature, to stop spoiling and slow down the growth of harmful bacteria. The cycle of refrigeration works by distributing the heat from the inside of the appliance to the outside, by using the principles of condensation and evaporation.

The standard parts of your refrigerator are. For questions or service call Gold Appliance Repair:


A compressor is both a motor and pump, and it is responsible for circulation of refrigerant in the system.
A compressor is an important part of a refrigerator. You should hire a professional service if the compressor is broken.


A refrigerator condenser is located on the back outside wall of the appliance and is there to disperse the warmth collected from inside the refrigerator out to the air.


A evaporator is located in the inside of the refrigerator where it absorbs the heat held within it, effectively lowering the interior temperature.

The moment the evaporator isn’t working, it is time to find a professional. Don’t wait too long.

Expansion Device

Liquid refrigerant is directed through a capillary tube which acts as an expansion tool as it cools the gas inside, turning it into liquid.


A thermostat regulates the temperature inside the refrigerator, beginning a new cooling cycle as required.

The thermostat inside of a refrigerator is very prone to problems. Troubleshoot and hire a repairman in New Orleans for repair the moment an issue occurs.

How Does Refrigeration Work?

1. Once the temperature inside the refrigerator rises above the set point sensors notify the refrigerator compressor to engage, and then the next cool down begins. The unit collects the cool liquified refrigerant, pressurizes and condenses it, and increases the temperature, turning it into a gas form.

2. The compressor guides the hot gas in the direction of the refrigerator condenser coils on the back of the refrigerator, where it comes into contact with the lower temperature in the kitchen and transforms back to a liquified form.

3. The cooled liquified gas continues on its trip to the evaporator, pushing through the coils within the appliance and top freezer compartment.

4. The refrigerant then absorbs the heated air from inside the refrigerator, lowering the temperature until it has reached the best set point.

5. The liquid will evaporate, and will return back to a gas form, and then returns to the refrigerator compressor in order to continue the cooling cycle.

Refrigeration is used in a number of applications and large appliances, including heat pumps, AC units, refrigerators and residential freezers. By removing warmth from one location and moving it to a different one the cycle of refrigeration helps cooling your house, provides a optimal space for food that is perishable, and helps with the manufacturing and storage of several different common products and goods.
