Parts of a Refrigerator

You will not find too many homes that don’t have a refrigerator in the kitchen. It has been a standard appliance for a lot of years. A household refrigerator stores food at the best temperature, in order to prevent rotting and limit bacteria. The cycle of refrigeration starts by distributing the heat from inside of the appliance to the exterior, by using principles of condensation and evaporation.

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


A refrigerator compressor is a combination of a motor and a pump, and it’s need for the circulation of refrigerant dispersed in the cooling system.
A compressor is a very important part of a refrigerator. You should call on a professional company if the compressor stops working.


A condenser is found on the rear exterior panel of the appliance and helps to release the warmth absorbed from inside the refrigerator then out to the surrounding air.


The refrigerator evaporator is stored on the inside of a refrigerator where absorbs warmth trapped within it, thereby reducing the interior temperature.

Right when an evaporator isn’t working, it is time to call a professional. Don’t wait too long.

Expansion Device

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


A thermostat regulates the current temperature throughout a refrigerator, starting the cooling period as needed.

A thermostat in a refrigerator is prone to malfunction. Troubleshoot and hire a technician in Nebraska for repair the moment a problem occurs.

How Does Refrigeration Work?

1. The moment the temperature within a refrigerator is higher than the set point sensors alert the refrigerator compressor to begin, and the next cool down starts. The appliance draws in the cold liquified refrigerant, then condenses and pressurizes the liquid, and raises the temperature, so it can turn into a gas form.

2. The refrigerator compressor unit guides the heated gas in the direction of the condenser coils located on the back of the appliance, where it comes in contact with the lower air temperature in the room and returns to a liquid state.

3. The cool liquified gas continues its trip towards the refrigerator evaporator, pushing through the many coils within the refrigerator and freezer section.

4. The liquid then absorbs the warm air from within the appliance, thereby cooling the temperature back to the correct set point.

5. The liquid then evaporates, and turns back to a gas state, and returns to the refrigerator compressor unit in order to continue the cycle.

Refrigeration technology is often used in quite a few applications and large appliances, including heat pumps, AC units, refrigerators and residential freezers. By extracting warmth from one place and then moving it to elsewhere the continuous cycle of refrigeration helps cooling a home, creates a safe environment for food that is perishable, and also helps with the manufacturing and storage of a number of different products and materials.
