Parts of a Refrigerator

There aren’t too many homes that don’t feature a refrigerator in the kitchen. It has been a must-own appliance for many years. A residential refrigerator stores your food at the best temperature, in order to reduce spoiling and slow down bacteria. The concept of refrigeration starts by transferring the heat from inside of the appliance to the exterior, relying on the principles of condensation and evaporation.

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


The refrigerator compressor is both a motor and a pump, and it’s necessary for the circulation of refrigerant dispensed in the system.
A compressor is an important piece of a refrigerator. Homeowners should enlist a professional company if the compressor is broken.


The condenser is attached on the rear exterior wall of the appliance and helps to disperse the warmth absorbed within the refrigerator out to the air.


The evaporator is installed on the inside of the refrigerator where it absorbs the warmth trapped inside of it, thereby lowering the interior temperature.

The moment an evaporator is not working, it’s time to find a professional. Do not wait too long.

Expansion Device

Liquid refrigerant is directed within a capillary tube that serves as an expansion device as it cools the gas, thereby transforming it back into a liquid.


The thermostat exists to regulate the temperature within a refrigerator, beginning the cooling cycle as needed.

The thermostat inside of a refrigerator is often prone to issues. Troubleshoot and hire a repairman in Pomona for repair the moment a problem happens.

How Does Refrigeration Work?

1. Right when the temperature in the interior of a refrigerator goes higher than the set point sensors alert the refrigerator compressor to begin, and then the cooling cycle begins. The unit attracts the cool liquified refrigerant, condenses and pressurizes the refrigerant, and raises the temperature, so it can turn into a gas.

2. The compressor pushes the heated gas towards the refrigerator condenser coils located on the back of the unit, where it comes in contact with the lower air temperature in the home and transforms to a liquid state.

3. The cool liquid continues on its trip towards the refrigerator evaporator, pushing through the many coils on the interior of the appliance and top freezer compartment.

4. The refrigerant then absorbs the heated air from inside the refrigerator, reducing the temperature until it has reached the optimal final point.

5. The refrigerant will evaporate, and turns back to a gas, and returns to the compressor unit to then continue the cycle.

Refrigeration technology is found in many applications and household appliances, including heat pumps, air conditioners, refrigerators and freezers. By removing warmth from one area and then transferring it to another the cycle of refrigeration aids in cooling your house, creates a optimal storage space for perishable food, and also helps with manufacturing and storage of many different common products and materials.
