Parts of a Refrigerator

There are not many homes that don’t feature a refrigerator inside the kitchen. It has been a must-have household appliance for several years. A residential refrigerator stores your food at the optimal temperature, in order to prevent rotting and limit harmful bacteria. The process of refrigeration works by transferring the heat from the inside of the unit to the exterior, relying on the principles of condensation and evaporation.

The components of your refrigerator are. For questions or service call Cox Appliance Repair:


The refrigerator compressor is a combo of a motor and pump, and it is need for circulation of refrigerant in the cooling system.
The compressor is a very important part of a refrigerator. Homeowners should call on a professional service if the compressor is broken.


A condenser is located on the rear outside panel of the appliance and helps to emit the warmth collected within the refrigerator then out in the air.


The refrigerator evaporator is located on the interior of the refrigerator where it absorbs warmth contained within it, effectively lowering the temperature inside the refrigerator.

The moment the evaporator stops working, it is time to call a professional. Do not wait until it’s too late.

Expansion Device

Liquid coolant is carried through a capillary tube that serves as an expansion device to cool the gas, thereby transforming the gas back into a liquid.


A refrigerator thermostat helps regulate the current temperature throughout a refrigerator, starting a new cooling period when it is needed.

A thermostat in a refrigerator is often prone to problems. Troubleshoot and hire a technician in Anaheim for service the moment a problem happens.

How Does Refrigeration Work?

1. The moment the temperature in the interior of the refrigerator is above the set point sensors signal the refrigerator compressor to engage, and the cooling period begins. The unit collects the cold liquified refrigerant, pressurizes and condenses the refrigerant, and raises the temperature, in order to turn it into a gas form.

2. The compressor unit pushes the heated gas in the direction of the condenser coils located on the rear of the unit, at which point it comes into contact with the lower temperature in the home and returns back to a liquified state.

3. The cooled liquified gas continues on its journey towards the evaporator, making its way through the many coils within the appliance and top freezer compartment.

4. The liquid then absorbs the warm air from inside the refrigerator, returning the temperature until it has reached the correct set point.

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

Refrigeration is used in several applications and household appliances, this includes heat pumps, air conditioners, refrigerators and freezers. By removing warmth from a single area and distributing it to another the continuous cycle of refrigeration will help cooling your house, creates a safe environment for food that is perishable, and also helps with manufacturing and storage of several different common products and goods.
