Parts of a Refrigerator

There aren’t many houses that don’t feature a refrigerator in the kitchen. It’s been a must-own kitchen appliance for many years now. A household refrigerator will store your food at the best temperature, in order to reduce spoilage and slow down harmful bacteria. The cycle of refrigeration works by moving the warmth from the interior of the appliance to the exterior, by using principles of condensation and evaporation.

The primary components of your refrigerator are. For questions or service call Fort Smith Appliance Repair:


A refrigerator compressor is both a pump and a motor, and it’s need for the circulation of refrigerant dispersed in the system.
A compressor is an important piece of a refrigerator. Homeowners should call on a professional service if the compressor is not working.


The condenser is found on the rear outside wall of the appliance and is there to emit the heat collected within the refrigerator out to the surrounding air.


The refrigerator evaporator is located in the inside of the refrigerator where it absorbs the warmth held inside of it, thereby lowering the temperature inside the refrigerator.

The moment the evaporator isn’t working, it’s time to call a professional. Do not wait too long.

Expansion Device

Liquified refrigerant is carried through a capillary tube which serves as an expansion device as it cools the gas, turning it back into a liquid.


The thermostat will regulate the temperature throughout a refrigerator, engaging a new cooling cycle when it is necessary.

A thermostat in a refrigerator is very prone to breaking. Troubleshoot and hire a technician in Fort Smith for service right when an issue occurs.

How Does Refrigeration Work?

1. When the temperature inside a refrigerator rises higher than the set point sensors signal the compressor to start, and the cool down starts. The refrigerator attracts the cold liquified refrigerant, pressurizes and condenses the refrigerant, and increases the temperature, in order to turn it into a gas form.

2. The compressor guides the warm gas towards the condenser coils on the exterior of the refrigerator, at which point it comes in contact with the lower temperature in the room and returns to a liquified form.

3. The cool liquified gas continues its journey to the evaporator, pushing through the many coils within the refrigerator and top freezer compartment.

4. The coolant then absorbs the hot air from the interior of the refrigerator, lowering the temperature back to the correct set point.

5. The refrigerant will evaporate, and will turn back into a gas, and then returns to the compressor so it can continue the cycle.

Refrigeration is often used in a number of applications and large appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By contracting warmth from a single location and then moving it to somewhere else the continuous cycle of refrigeration contributes in cooling a house, provides a perfect environment for perishable food, and also helps with manufacturing and storage of many different products and materials.
