Parts of a Refrigerator

You won’t find many houses that don’t feature a refrigerator in the kitchen. It’s been a must-have household appliance for many years now. A refrigerator will store your food and drinks at the right temperature, in order to prevent rotting and slow down the growth of bacteria. The cycle of refrigeration starts by distributing the warmth from the inside of the appliance to the outside, by using the principles of evaporation and condensation.

The components of a refrigerator are below. For questions or service call Dawson’s Appliance Repair:


A compressor is both a pump and motor, and it’s necessary for the circulation of refrigerant in the cooling system.
A compressor is an integral part of a refrigerator. Homeowners should enlist a professional service if the compressor is broken.


The refrigerator condenser is attached on the back exterior panel of the refrigerator and helps to disperse the warmth absorbed from within the refrigerator then out into the air.


The evaporator is attached in the interior of the refrigerator where absorbs warmth trapped within it, thereby lowering the interior temperature.

Right when an evaporator stops working, it is time to enlist a professional. You should not wait too long.

Expansion Device

Liquid coolant is directed within a capillary tube which works as an expansion tool to cool the gas, turning the gas back into a liquid.


A refrigerator thermostat helps regulate the current temperature throughout a refrigerator, engaging a new cooling period when it is necessary.

The thermostat in a refrigerator is very prone to problems. Troubleshoot and hire a contractor in CITY for repair the moment a problem happens.

How Does Refrigeration Work?

1. Once the temperature in the interior of the refrigerator rises above the set point sensors notify the refrigerator compressor to begin, and the cooling cycle begins. The unit collects the cool liquified refrigerant, condenses and pressurizes it, and increases the temperature, in order to turn it into a gas form.

2. The compressor directs the warm gas in the direction of the refrigerator condenser coils on the back of the appliance, where it comes in contact with the lower air temperature in the room and returns back to a liquified form.

3. The cooled refrigerant then continues its trip to the evaporator component, making its way through the many coils in the inside of the appliance and top freezer compartment.

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

5. The refrigerant evaporates, and will return back into a gas state, and returns to the compressor in order to continue the cooling cycle.

Refrigeration is used in a lot of applications and large appliances, including heat pumps, air conditioners, refrigerators and freezers. By removing heat from one place and transferring it to another the continuous cycle of refrigeration helps cooling a home, provides a optimal environment for perishable food, and also helps with the manufacturing and storage of many different common products and materials.
