Parts of a Refrigerator

You will not find too many homes that don’t have a refrigerator in the kitchen. It has been a must-own kitchen appliance for several years. A residential refrigerator stores food and drinks at the right temperature, to prevent rotting and slow down the growth of bacteria. The cycle of refrigeration works by moving the heat from inside of the appliance to the outside, relying on principles of evaporation and condensation.

The parts of a refrigerator are below. For questions or service call Direct Oceanside Appliance Repair:


The refrigerator compressor is a combination of a motor and pump, and it’s responsible for the circulation of refrigerant throughout the system.
A compressor is a very important piece of a refrigerator. You should call a professional company if the compressor is broken.


The refrigerator condenser is found on the back outside wall of the appliance and is there to disperse the warmth built-up within the refrigerator out into the surrounding air.


The refrigerator evaporator is stored on the inside of the refrigerator where absorbs warmth held within it, effectively reducing the interior temperature.

Right when an evaporator stops working, it is time to enlist a professional. Don’t wait until it’s too late.

Expansion Device

Liquified coolant is carried within a capillary tube that acts as an expansion tool to cool the gas, thereby transforming it back into liquid.


The refrigerator thermostat will regulate the temperature in the interior of the refrigerator, engaging the cooling cycle when it is necessary.

The thermostat in a refrigerator is prone to issues. Troubleshoot and hire a contractor in Oceanside for service the moment a problem occurs.

How Does Refrigeration Work?

1. Once the temperature within a refrigerator goes higher than the set point sensors signal the compressor to start, and the next cooling period starts. The appliance collects the cold liquid refrigerant, condenses and pressurizes the refrigerant, and raises the temperature, so it can turn into a gas.

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

3. The cooled refrigerant then continues its journey to the refrigerator evaporator component, traveling through the many coils on the inside of the refrigerator and freezer.

4. The coolant then absorbs the hot air from inside the refrigerator, thereby returning the temperature until it has reached the best final point.

5. The refrigerant then evaporates, and will return back into a gas form, and returns to the refrigerator compressor unit in order to continue the cycle.

Refrigeration is found in quite a few applications and household appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By extracting heat from a single place and then relocating it to somewhere else the continuous cycle of refrigeration aids in cooling your house, provides a safe environment for perishable food, and helps with the manufacturing and storage of many different everyday products and materials.
