Parts of a Refrigerator

There are not many homes that do not have a refrigerator inside the kitchen. It has been a must-own kitchen appliance for a lot of years now. A household refrigerator will store food and drinks at the optimal temperature, in order to eliminate spoiling and stop the growth of bacteria. The cycle of refrigeration works by moving the heat from inside of the appliance to the exterior, using principles of evaporation and condensation.

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


A compressor is a combination of a pump and a motor, and it is responsible for the circulation of refrigerant throughout the cooling system.
The compressor is a very important part of a refrigerator. Homeowners should call a professional company if the compressor is broken.


A refrigerator condenser is located on the back exterior wall of the appliance and is there to release the heat absorbed from inside the refrigerator then out into the air.


A evaporator is located on the interior of a refrigerator where it absorbs heat trapped within it, thereby reducing the interior temperature.

The moment an evaporator isn’t working, it is time to find a professional. Do not wait too long.

Expansion Device

Liquified coolant is carried within a capillary tube which serves as an expansion tool to cool the gas inside, turning it into liquid.


A refrigerator thermostat regulates the current temperature inside the refrigerator, beginning a new cooling period as it is required.

The thermostat inside of a refrigerator is often prone to issues. Troubleshoot and hire a repairman in Rancho Cucamonga for repair the moment an issue occurs.

How Does Refrigeration Work?

1. Right when the temperature inside a refrigerator rises higher than the set point sensors signal the compressor to start, and then the next cool down begins. The unit collects the cool liquified refrigerant, then pressurizes and condenses the liquid, and raises the temperature, in order to turn it into a gas.

2. The refrigerator compressor directs the heated gas towards the refrigerator condenser coils located on the exterior of the refrigerator, where it comes into contact with the lower temperature in the room and reverts to a liquified form.

3. The cool liquified gas continues on its trip towards the evaporator component, traveling through the many coils on the inside of the refrigerator and top freezer section.

4. The liquid absorbs the hot air from inside the refrigerator, reducing the temperature until it has reached the best final point.

5. The coolant evaporates, and turns back to a gas state, and then returns to the compressor in order to continue the cooling cycle.

Refrigeration is often found in several applications and appliances, this includes heat pumps, air conditioners, refrigerators and freezers. By removing warmth from a single location and transferring it to somewhere else the cycle of refrigeration contributes in cooling a home, creates a perfect environment for perishable food, and also helps with manufacturing and storage of many different common products and goods.
