Parts of a Refrigerator

You will not find many homes that do not feature a refrigerator inside the kitchen. It’s been a standard household appliance for a lot of years now. A residential refrigerator stores your food and drinks at the optimal temperature, in order to prevent spoilage and stop the growth of bacteria. The process of refrigeration starts by transferring the heat from the interior of the appliance to the outside, by using the principles of condensation and evaporation.

The parts of your refrigerator are below. For questions or service call Elroy Appliance Repair:


The refrigerator compressor is both a pump and motor, and it is necessary for the circulation of refrigerant throughout the cooling system.
The compressor is a very important part of a refrigerator. You should call a professional service if the compressor isn’t working.


A refrigerator condenser is located on the rear outside panel of the refrigerator and will help to release the warmth absorbed from inside the refrigerator then out in the air.


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

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

Expansion Device

Liquid coolant is carried within a capillary tube that works as an expansion tool to cool the gas inside, thereby turning it back into liquid.


The thermostat regulates the temperature inside a refrigerator, starting the cooling period as needed.

The thermostat inside of a refrigerator is prone to problems. Troubleshoot and hire a technician in Tennessee for service right after an issue occurs.

How Does Refrigeration Work?

1. Once the temperature within the refrigerator is above the set point sensors signal the refrigerator compressor to start, and then the next cool down begins. The unit collects the cool liquid refrigerant, then condenses and pressurizes it, and increases the temperature, in order to turn it into a gas.

2. The refrigerator compressor unit pushes the heated gas towards the refrigerator condenser coils located on the exterior of the refrigerator, at which point it comes in contact with the lower air temperature in the room and transforms to a liquified state.

3. The cooled liquid then continues on its trip towards the refrigerator evaporator component, finding its way through the coils within the appliance and top freezer section.

4. The coolant absorbs the heated air from the interior of the appliance, returning the temperature down to the best set point.

5. The coolant evaporates, and will return back to a gas, and returns to the compressor in order to then continue the cycle.

Refrigeration is found in many applications and household appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By contracting heat from one area and then relocating it to somewhere else the cycle of refrigeration aids in cooling your house, provides a optimal environment for perishable food, and also helps with the manufacturing and storage of many different everyday products and materials.
