In order to get the most use possible out of this kitchen appliance it can be useful to understand exactly how a refrigerator keeps food cold—and Vaughn’s Appliance Repair is here to explain.

Read below to learn what you might need to know concerning how refrigerators run, how it cools your food and if it is time to call refrigerator repair CITY.

Parts of a Refrigerator

There are not many houses that do not have a refrigerator in the kitchen. It’s been a must-own kitchen appliance for several years now. A refrigerator stores your food and drinks at the best temperature, to prevent spoilage and slow down the growth of harmful bacteria. The concept of refrigeration starts by distributing the warmth from the inside of the appliance to the exterior, relying on the principles of evaporation and condensation.

The main components of your refrigerator are. For questions or service call Vaughn’s Appliance Repair:


A refrigerator compressor is a combination of a pump and a motor, and it is necessary for the circulation of refrigerant in the system.
The compressor is an integral piece of a refrigerator. You should enlist a professional company if the compressor is broken.


A condenser is found on the rear outside panel of the refrigerator and is there to emit the heat collected from within the refrigerator out in the surrounding air.


A evaporator is attached in the interior of the refrigerator where it absorbs heat trapped inside of it, effectively lowering the temperature inside.

The moment the evaporator stops working, it’s time to find a professional. Do not wait too long.

Expansion Device

Liquid coolant is carried through a capillary tube which works as an expansion device to cool the gas inside, thereby transforming it into a liquid.


The refrigerator thermostat regulates the temperature in the interior of the refrigerator, starting a new cooling period as it is necessary.

A thermostat in a refrigerator is very prone to problems. Troubleshoot and hire a repairman in CITY for service right when a problem occurs.

How Does Refrigeration Work?

1. When the temperature within a refrigerator goes higher than the set point sensors signal the refrigerator compressor to start, and the cooling cycle begins. The refrigerator collects the cold liquid refrigerant, condenses and pressurizes it, and raises the temperature, turning it into a gas form.

2. The compressor unit pushes the hot gas in the direction of the condenser coils on the outside of the appliance, at which point it comes in contact with warmer temperature in the home and reverts to a liquified form.

3. The cooled liquified gas then continues its journey towards the evaporator component, traveling through the coils on the inside of the refrigerator and freezer.

4. The liquid absorbs the heated air from inside the refrigerator, thereby returning the temperature until it has reached the best final point.

5. The coolant will evaporate, and will turn back into a gas, and then returns to the refrigerator compressor to then continue the cooling cycle.

Refrigeration is often found in a lot of applications and household appliances, this includes heat pumps, AC units, refrigerators and freezers. By removing heat from one location and then moving it to somewhere else the cycle of refrigeration will help cooling your home, provides a perfect space for perishable food, and helps with the manufacturing and storage of a lot of different products and materials.
