Parts of a Refrigerator

There are not many houses that do not have a refrigerator in the kitchen. It’s been a standard household appliance for several years. A residential refrigerator stores your food and drinks at the best temperature, in order to reduce spoiling and slow down the growth of harmful bacteria. The cycle of refrigeration works by transferring the heat from the interior of the refrigerator to the outside, by using principles of condensation and evaporation.

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


The compressor is a combo of a pump and motor, and it’s responsible for circulation of refrigerant dispersed in the cooling system.
The compressor is an important part of a refrigerator. Homeowners should call a professional company if the compressor is broken.


The refrigerator condenser is found on the rear outside wall of the appliance and helps to disperse the warmth absorbed within the refrigerator then out in the surrounding air.


The refrigerator evaporator is stored in the inside of a refrigerator where it absorbs heat trapped within it, effectively lowering the temperature inside the unit.

Once an evaporator stops working, it’s time to hire a professional. Do not wait too long.

Expansion Device

Liquified coolant is transferred within a capillary tube that serves as an expansion tool as it cools the gas inside, transforming it back into liquid.


The refrigerator thermostat exists to regulate the temperature throughout the refrigerator, engaging a new cooling cycle as appropriate.

The thermostat inside of a refrigerator is often prone to breaking. Troubleshoot and call a contractor in CITY for service the moment a problem happens.

How Does Refrigeration Work?

1. Right when the temperature in the interior of a refrigerator is above the set point sensors alert the compressor to engage, and the cool down begins. The unit draws in the cold liquified refrigerant, pressurizes and condenses it, and raises the temperature, so it can turn into a gas form.

2. The compressor pushes the hot gas towards the refrigerator condenser coils located on the back of the appliance, at which point it comes in contact with warmer air temperature in the room and reverts to a liquified form.

3. The cool refrigerant continues on its journey towards the evaporator, making its way through the many coils within the appliance and freezer compartment.

4. The coolant absorbs the heated air from the interior of the appliance, lowering the temperature back to the best final point.

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

Refrigeration is often used in a lot of applications and appliances, including heat pumps, AC units, refrigerators and freezers. By removing heat from a single location and then transferring it to another the continuous cycle of refrigeration aids in cooling your home, provides a perfect space for food that is perishable, and also helps with the manufacturing and storage of many different common products and goods.
