Parts of a Refrigerator

You will not find too many homes that don’t have a refrigerator inside the kitchen. It has been a standard appliance for a lot of years. A household refrigerator stores food at the best temperature, to stop rotting and limit harmful bacteria. The cycle of refrigeration works by moving the warmth from the interior of the unit to the exterior, using the principles of condensation and evaporation.

The standard parts of a refrigerator are below. For questions or service call Eastvale Appliance Repair:


The refrigerator compressor is both a pump and a motor, and it is responsible for the circulation of refrigerant dispersed in the cooling system.
The compressor is an important part of a refrigerator. You should call a professional service if the compressor is broken.


A refrigerator condenser is found on the back outside panel of the appliance and is there to disperse the warmth collected from inside the refrigerator out to the air.


The evaporator is stored on the inside of a refrigerator where it absorbs the heat trapped within it, thereby lowering the interior temperature.

Right when the evaporator stops working, it’s time to find a professional. You should not wait until it is too late.

Expansion Device

Liquid refrigerant is transferred through a capillary tube that acts as an expansion tool to cool the gas, thereby transforming the gas back into liquid.


A thermostat regulates the current temperature within the refrigerator, starting the cooling cycle when required.

A thermostat in a refrigerator is often prone to breaking. Troubleshoot and call a technician in Eastvale for service right after an issue occurs.

How Does Refrigeration Work?

1. Once the temperature within the refrigerator rises higher than the set point sensors signal the refrigerator compressor to start, and then the next cooling cycle begins. The refrigerator draws in the cool liquified refrigerant, pressurizes and condenses the liquid, and increases the temperature, in order to turn it into a gas.

2. The refrigerator compressor unit pushes the warm gas in the direction of the refrigerator condenser coils on the exterior of the appliance, where it comes into contact with the lower temperature in the home and returns to a liquid form.

3. The cooled refrigerant then continues on its journey to the refrigerator evaporator component, pushing through the coils on the inside of the appliance and freezer compartment.

4. The liquid then absorbs the heated air from within the appliance, reducing the temperature back to the correct final point.

5. The refrigerant then will evaporate, and turns back to a gas, and then returns to the refrigerator compressor in order to then continue the cooling cycle.

Refrigeration technology is often used in several applications and appliances, including heat pumps, air conditioners, refrigerators and freezers. By contracting heat from one area and then distributing it to a different one the continuous cycle of refrigeration aids in cooling your home, creates a safe storage space for perishable food, and helps with manufacturing and storage of several different products and materials.
