Parts of a Refrigerator

There aren’t many houses that do not feature a refrigerator inside the kitchen. It’s been a must-have kitchen appliance for many years. A household refrigerator stores food at the right temperature, in order to prevent rotting and stop harmful bacteria. The cycle of refrigeration works by moving the warmth from the inside of the appliance to the outside, by using the principles of evaporation and condensation.

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


A compressor is both a motor and pump, and it is need for circulation of refrigerant in the cooling system.
A compressor is a very important piece of a refrigerator. Homeowners should hire a professional service if the compressor is not working.


A refrigerator condenser is attached on the back outside wall of the refrigerator and is there to release the heat absorbed inside the refrigerator then out into the surrounding air.


The refrigerator evaporator is housed on the interior of the refrigerator where absorbs the heat contained inside of it, thereby lowering the interior temperature.

Once an evaporator stops working, it’s time to find a professional. Don’t wait until it’s too late.

Expansion Device

Liquid refrigerant is transported within a capillary tube that acts as an expansion tool to cool the gas inside, transforming the gas back into liquid.


A thermostat regulates the temperature inside a refrigerator, starting a new cooling cycle as it is appropriate.

A thermostat in a refrigerator is often prone to breaking. Troubleshoot and call a repairman in Arizona for service right when an issue happens.

How Does Refrigeration Work?

1. The moment the temperature within a refrigerator rises higher than the set point sensors signal the compressor to begin, and the cool down starts. The refrigerator draws in the cool liquified refrigerant, pressurizes and condenses the refrigerant, and increases the temperature, turning it into a gas.

2. The compressor directs the heated gas in the direction of the condenser coils located on the exterior of the unit, where it comes in contact with warmer temperature in the kitchen and returns to a liquified form.

3. The cool refrigerant continues its trip towards the evaporator, traveling through the coils within the refrigerator and freezer.

4. The refrigerant then absorbs the warm air from the interior of the appliance, thereby cooling the temperature until it has reached the correct set point.

5. The coolant evaporates, and turns back to a gas state, and returns to the refrigerator compressor unit to then continue the cycle.

Refrigeration technology is often used in several applications and household appliances, this includes heat pumps, AC units, refrigerators and freezers. By contracting heat from one place and distributing it to a different one the continuous cycle of refrigeration will help cooling your house, provides a optimal environment for food that is perishable, and also helps with the manufacturing and storage of many different common products and goods.
