Parts of a Refrigerator

You will not find many homes that do not have a refrigerator inside the kitchen. It has been a standard kitchen appliance for many years now. A refrigerator can store food at the best temperature, in order to stop spoiling and stop the growth of harmful bacteria. The process of refrigeration works by moving the heat from the inside of the refrigerator to the exterior, using principles of evaporation and condensation.

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


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


The condenser is attached on the rear outside panel of the refrigerator and will help to emit the warmth absorbed within the refrigerator then out into the air.


The evaporator is stored in the inside of the refrigerator where it absorbs heat trapped within it, effectively lowering the temperature inside the appliance.

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

Expansion Device

Liquified refrigerant is transferred within a capillary tube that works as an expansion tool to cool the gas inside, thereby transforming the gas into a liquid.


A thermostat helps regulate the current temperature within a refrigerator, starting a new cooling period when appropriate.

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

How Does Refrigeration Work?

1. Right when the temperature inside the refrigerator rises above the set point sensors signal the compressor to engage, and then the cool down starts. The appliance attracts the cool liquid refrigerant, condenses and pressurizes it, and raises the temperature, turning it into a gas form.

2. The refrigerator compressor unit guides the warm gas towards the refrigerator condenser coils on the exterior of the appliance, where it comes into contact with warmer air temperature in the home and transforms back to a liquified form.

3. The cooled liquid then continues its journey towards the evaporator, traveling through the coils within the refrigerator and top freezer.

4. The refrigerant absorbs the heated air from inside the refrigerator, thereby returning the temperature until it has reached the optimal set point.

5. The liquid will evaporate, and turns back into a gas form, and returns to the compressor unit to then continue the cycle.

Refrigeration technology is often used in several applications and household appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By contracting warmth from a single place and transferring it to somewhere else the continuous cycle of refrigeration will help cooling your house, creates a optimal storage space for food that is perishable, and also helps with the manufacturing and storage of many different common products and materials.
