Parts of a Refrigerator

There aren’t too many homes that don’t have a refrigerator inside the kitchen. It’s been a must-have appliance for several years now. A residential refrigerator stores your food at the optimal temperature, in order to reduce rotting and limit bacteria. The process of refrigeration starts by transferring the heat from the interior of the appliance to the outside, by relying on principles of condensation and evaporation.

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


The refrigerator compressor is a combination of a motor and a pump, and it’s need for the circulation of refrigerant in the system.
A compressor is an integral piece of a refrigerator. Homeowners should call on a professional company if the compressor isn’t working.


A condenser is attached on the rear exterior wall of the appliance and is there to release the warmth absorbed from inside the refrigerator out to the air.


A evaporator is located in the interior of a refrigerator where absorbs heat contained inside of it, thereby lowering the temperature inside.

The moment an evaporator stops working, it is time to find a professional. You should not wait too long.

Expansion Device

Liquid coolant is transported within a capillary tube that acts as an expansion device as it cools the gas, transforming it back into liquid.


The refrigerator thermostat exists to regulate the current temperature throughout the refrigerator, starting a new cooling period as it is needed.

A thermostat in a refrigerator is prone to problems. Troubleshoot and call a technician in Arlington for repair the moment a problem occurs.

How Does Refrigeration Work?

1. Right when the temperature within the refrigerator rises above the set point sensors alert the refrigerator compressor to start, and then the cool down starts. The refrigerator collects the cool liquified refrigerant, pressurizes and condenses the refrigerant, and raises the temperature, in order to turn it into a gas.

2. The refrigerator compressor directs the warm gas in the direction of the condenser coils on the outside of the refrigerator, where it comes into contact with warmer air temperature in the home and transforms back to a liquid form.

3. The cool liquid then continues on its trip towards the evaporator component, pushing through the coils within the appliance and freezer.

4. The liquid then absorbs the hot air from inside the refrigerator, thereby cooling the temperature back to the optimal set point.

5. The liquid will evaporate, and will turn back into a gas state, and then returns to the compressor to then continue the cycle.

Refrigeration technology is often used in quite a few applications and appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By extracting heat from one place and transferring it to a different one the cycle of refrigeration helps cooling your home, creates a optimal environment for perishable food, and helps with the manufacturing and storage of a lot of different common products and materials.
