Parts of a Refrigerator

You will not find too many houses that do not have a refrigerator in the kitchen. It has been a must-own kitchen appliance for many years now. A refrigerator will store your food at the best temperature, in order to prevent rotting and limit the growth of bacteria. The process of refrigeration works by transferring the warmth from inside of the appliance to the exterior, relying on principles of condensation and evaporation.

The primary components of your refrigerator are. For questions or service call J&L Thousand Oaks Appliance Repair:


A refrigerator compressor is both a pump and motor, and it’s necessary for circulation of refrigerant dispensed in the cooling system.
A compressor is an integral part of a refrigerator. You should hire a professional company if the compressor is broken.


A condenser is located on the rear exterior panel of the appliance and helps to disperse the warmth absorbed inside the refrigerator out in the air.


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

Once an evaporator isn’t working, it’s time to enlist a professional. You should not wait too long.

Expansion Device

Liquid refrigerant is carried through a capillary tube that works as an expansion tool to cool the gas, thereby turning the gas into a liquid.


A thermostat helps regulate the temperature throughout the refrigerator, starting the cooling cycle when it is necessary.

A thermostat in a refrigerator is often prone to breaking. Troubleshoot and hire a contractor in Thousand Oaks for repair right when a problem occurs.

How Does Refrigeration Work?

1. Once the temperature in the interior of a refrigerator rises higher than the set point sensors signal the compressor to begin, and then the next cooling period starts. The unit draws in the cold liquified refrigerant, then pressurizes and condenses it, and raises the temperature, turning it into a gas.

2. The refrigerator compressor unit pushes the hot gas in the direction of the condenser coils on the exterior of the appliance, where it comes in contact with warmer air temperature in the kitchen and returns back to a liquified form.

3. The cool liquid then continues its journey to the evaporator component, pushing through the coils in the inside of the refrigerator and top freezer.

4. The coolant then absorbs the heated air from inside the refrigerator, thereby lowering the temperature until it has reached the desired final point.

5. The refrigerant evaporates, and will turn back to a gas state, and returns to the refrigerator compressor so it can continue the cooling cycle.

Refrigeration technology is often found in several applications and household appliances, including heat pumps, AC units, refrigerators and residential freezers. By removing heat from one area and then transferring it to elsewhere the cycle of refrigeration aids in cooling your house, provides a perfect storage space for food that is perishable, and also helps with the manufacturing and storage of several different products and materials.
