Parts of a Refrigerator

There aren’t too many houses that don’t feature a refrigerator inside the kitchen. It’s been a must-own kitchen appliance for a lot of years now. A household refrigerator can store food and drinks at the optimal temperature, in order to prevent spoiling and limit bacteria. The process of refrigeration starts by moving the heat from the inside of the refrigerator to the exterior, relying on principles of condensation and evaporation.

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


The refrigerator compressor is both a pump and motor, and it is need for circulation of refrigerant dispersed in the system.
The compressor is a very important piece of a refrigerator. Homeowners should call a professional service if the compressor is broken.


A refrigerator condenser is located on the back outside wall of the refrigerator and is there to emit the heat collected from within the refrigerator out in the surrounding air.


The evaporator is located on the inside of the refrigerator where it absorbs the warmth held inside of it, thereby reducing the interior temperature.

The moment the evaporator isn’t working, it is time to hire a professional. Do not wait until it is too late.

Expansion Device

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


The thermostat exists to regulate the temperature in the interior of a refrigerator, beginning a new cooling cycle when required.

The thermostat inside of a refrigerator is prone to breaking. Troubleshoot and call a repairman in South Dakota for service the moment a problem happens.

How Does Refrigeration Work?

1. Right when the temperature within the refrigerator goes above the set point sensors signal the refrigerator compressor to start, and the next cool down begins. The unit draws in the cold liquified refrigerant, condenses and pressurizes the liquid, and increases the temperature, turning it into a gas.

2. The compressor pushes the heated gas towards the condenser coils located on the back of the unit, where it comes into contact with the lower air temperature in the room and reverts to a liquid form.

3. The cool liquified gas then continues on its trip towards the refrigerator evaporator component, pushing through the coils on the inside of the appliance and top freezer section.

4. The refrigerant then absorbs the heated air from inside the appliance, thereby lowering the temperature until it has reached the optimal set point.

5. The liquid then evaporates, and turns back into a gas state, and returns to the refrigerator compressor so it can continue the cycle.

Refrigeration technology is used in several applications and appliances, this includes heat pumps, AC units, refrigerators and freezers. By extracting heat from a single area and transferring it to a different one the continuous cycle of refrigeration contributes in cooling a house, creates a optimal environment for perishable food, and also helps with the manufacturing and storage of a lot of different everyday products and materials.
