Parts of a Refrigerator

You will not find too many houses that don’t feature a refrigerator inside the kitchen. It’s been a must-have household appliance for many years now. A household refrigerator is able to store your food and drinks at the best temperature, to reduce rotting and limit the growth of bacteria. The process of refrigeration starts by transferring the warmth from the interior of the refrigerator to the outside, by relying on principles of condensation and evaporation.

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


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


A refrigerator condenser is attached on the rear exterior panel of the appliance and will help to disperse the heat collected inside the refrigerator out in the air.


A evaporator is located in the inside of the refrigerator where absorbs warmth contained inside of it, thereby lowering the temperature inside the unit.

Once the evaporator isn’t working, it’s time to call a professional. Don’t wait too long.

Expansion Device

Liquified refrigerant is transported within a capillary tube which serves as an expansion device to cool the gas, turning it back into liquid.


The refrigerator thermostat exists to regulate the temperature throughout the refrigerator, beginning a new cooling period as necessary.

The thermostat inside of a refrigerator is often prone to malfunction. Troubleshoot and hire a contractor in California for service right after an issue happens.

How Does Refrigeration Work?

1. The moment the temperature within a refrigerator goes above the set point sensors alert the refrigerator compressor to begin, and then the cool down starts. The unit collects the cold liquified refrigerant, then pressurizes and condenses the refrigerant, and raises the temperature, in order to turn it into a gas form.

2. The compressor guides the warm gas in the direction of the condenser coils on the exterior of the unit, at which point it comes in contact with the lower temperature in the room and reverts back to a liquified state.

3. The cool liquified gas then continues its journey to the refrigerator evaporator component, traveling through the many coils within the refrigerator and freezer compartment.

4. The coolant absorbs the hot air from inside the appliance, lowering the temperature until it has reached the correct final point.

5. The refrigerant then will evaporate, and turns back into a gas form, and returns to the refrigerator compressor so it can then continue the cooling cycle.

Refrigeration is found in a number of applications and large appliances, this includes heat pumps, air conditioners, refrigerators and residential freezers. By extracting warmth from a single place and then relocating it to a different one the cycle of refrigeration helps cooling a house, creates a safe space for food that is perishable, and also helps with the manufacturing and storage of many different everyday products and goods.
