Parts of a Refrigerator

There aren’t many homes that do not have a refrigerator in the kitchen. It’s been a must-own appliance for many years. A household refrigerator will store your food at the right temperature, in order to eliminate spoiling and limit the growth of bacteria. The cycle of refrigeration starts by transferring the warmth from inside of the unit to the outside, using the principles of evaporation and condensation.

The main parts of a refrigerator are. For questions or service call Power Appliance Repair:


The refrigerator compressor is a combination of a pump and a motor, and it’s necessary for the circulation of refrigerant in the cooling system.
A compressor is an important piece of a refrigerator. You should hire a professional company if the compressor isn’t working.


A refrigerator condenser is found on the back outside panel of the appliance and helps to release the warmth absorbed from inside the refrigerator out to the surrounding air.


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

Right when an evaporator stops working, it’s time to find a professional. Don’t wait too long.

Expansion Device

Liquid refrigerant is directed through a capillary tube that works as an expansion device to cool the gas, transforming the gas back into a liquid.


A refrigerator thermostat regulates the current temperature inside the refrigerator, engaging a new cooling cycle when necessary.

A thermostat in a refrigerator is often prone to malfunction. Troubleshoot and hire a technician in Reston for service right when a problem happens.

How Does Refrigeration Work?

1. When the temperature within a refrigerator goes higher than the set point sensors signal the refrigerator compressor to engage, and the next cooling cycle starts. The appliance attracts the cold liquified refrigerant, then pressurizes and condenses it, and increases the temperature, turning it into a gas.

2. The compressor unit guides the warm gas in the direction of the refrigerator condenser coils on the outside of the unit, at which point it comes into contact with the lower temperature in the kitchen and returns back to a liquid form.

3. The cooled refrigerant continues its journey to the evaporator, traveling through the coils on the inside of the appliance and top freezer section.

4. The refrigerant then absorbs the heated air from within the refrigerator, cooling the temperature until it has reached the correct final point.

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

Refrigeration is found in quite a few applications and household appliances, including heat pumps, air conditioners, refrigerators and freezers. By contracting warmth from one area and then relocating it to another the continuous cycle of refrigeration helps cooling your home, creates a perfect storage space for perishable food, and also helps with manufacturing and storage of a lot of different common products and goods.
