Parts of a Refrigerator

There aren’t too many houses that do not have a refrigerator in the kitchen. It has been a standard appliance for several years. A household refrigerator can store food at the optimal temperature, to eliminate rotting and slow down the growth of harmful bacteria. The process of refrigeration starts by distributing the warmth from the inside of the appliance to the outside, by using the principles of evaporation and condensation.

The primary components of your refrigerator are below. For questions or service call Appliance Repair Force:


A compressor is a combination of a pump and a motor, and it’s necessary for circulation of refrigerant in the cooling system.
The compressor is a very important part of a refrigerator. Homeowners should enlist a professional company if the compressor is broken.


The condenser is located on the rear outside wall of the refrigerator and helps to release the heat collected within the refrigerator out in the surrounding air.


A evaporator is attached on the inside of a refrigerator where absorbs heat trapped inside of it, thereby reducing the interior temperature.

The moment an evaporator is not working, it’s time to enlist a professional. Don’t wait too long.

Expansion Device

Liquid coolant is directed within a capillary tube which serves as an expansion tool as it cools the gas inside, turning it back into liquid.


A refrigerator thermostat regulates the current temperature within the refrigerator, starting the cooling period as it is appropriate.

A thermostat in a refrigerator is prone to malfunction. Troubleshoot and call a contractor in South and North Carolina for repair right after a problem occurs.

How Does Refrigeration Work?

1. Once the temperature within a refrigerator rises above the set point sensors signal the compressor to begin, and then the next cool down begins. The unit draws in the cool liquified refrigerant, condenses and pressurizes the liquid, and raises the temperature, turning it into a gas.

2. The refrigerator compressor unit guides the warm gas towards the refrigerator condenser coils on the back of the appliance, at which point it comes into contact with warmer temperature in the room and returns to a liquid form.

3. The cool liquid continues its journey to the evaporator, traveling through the many coils within the appliance and freezer.

4. The liquid then absorbs the warm air from inside the refrigerator, thereby reducing the temperature down to the best final point.

5. The liquid then will evaporate, and turns back into a gas form, and returns to the refrigerator compressor unit in order to then continue the cooling cycle.

Refrigeration is often used in quite a few applications and large appliances, this includes heat pumps, air conditioners, refrigerators and freezers. By removing warmth from one area and relocating it to elsewhere the continuous cycle of refrigeration contributes in cooling a house, provides a optimal storage space for food that is perishable, and helps with manufacturing and storage of many different common products and goods.
