Parts of a Refrigerator

There are not many homes that don’t have a refrigerator inside the kitchen. It’s been a must-have appliance for many years. A residential refrigerator is able to store your food at the optimal temperature, in order to reduce spoiling and slow down bacteria. The cycle of refrigeration starts by transferring the heat from inside of the refrigerator to the outside, by relying on principles of condensation and evaporation.

The main components of your refrigerator are below. For questions or service call C&B Chino Hills Appliance Repair:


A refrigerator compressor is both a pump and motor, and it’s necessary for circulation of refrigerant in the system.
The compressor is a very important part of a refrigerator. Homeowners should enlist a professional company if the compressor stops working.


A condenser is located on the back exterior wall of the refrigerator and is there to release the heat collected from inside the refrigerator then out to the surrounding air.


A evaporator is housed on the inside of a refrigerator where it absorbs the warmth trapped within it, effectively reducing the temperature inside the appliance.

Right when the evaporator isn’t working, it is time to find a professional. You should not wait too long.

Expansion Device

Liquid coolant is transported through a capillary tube that works as an expansion tool to cool the gas, transforming the gas back into liquid.


A thermostat regulates the current temperature within the refrigerator, engaging the cooling cycle as needed.

The thermostat in a refrigerator is very prone to problems. Troubleshoot and call a contractor in Chino Hills for service right when an issue occurs.

How Does Refrigeration Work?

1. The moment the temperature within the refrigerator goes above the set point sensors alert the refrigerator compressor to begin, and then the next cool down begins. The appliance collects the cool liquified refrigerant, pressurizes and condenses the refrigerant, and raises the temperature, so it can turn into a gas.

2. The refrigerator compressor unit pushes the heated gas towards the refrigerator condenser coils located on the exterior of the unit, at which point it comes in contact with the lower air temperature in the kitchen and reverts to a liquified form.

3. The cooled liquified gas then continues on its trip towards the evaporator component, pushing through the coils in the inside of the refrigerator and top freezer.

4. The refrigerant then absorbs the heated air from the interior of the appliance, thereby returning the temperature down to the desired set point.

5. The liquid evaporates, and turns back to a gas state, and returns to the refrigerator compressor so it can then continue the cycle.

Refrigeration technology is often used in several applications and appliances, including heat pumps, AC units, refrigerators and freezers. By extracting heat from one place and transferring it to another the continuous cycle of refrigeration will help cooling a home, provides a optimal environment for food that is perishable, and helps with the manufacturing and storage of a number of different common products and goods.
