Parts of a Refrigerator

You won’t find many houses that do not feature a refrigerator inside the kitchen. It’s been a must-have appliance for a lot of years now. A residential refrigerator will store food and drinks at the best temperature, to eliminate rotting and stop the growth of harmful bacteria. The cycle of refrigeration starts by moving the heat from the interior of the refrigerator to the outside, using principles of evaporation and condensation.

The primary components of a refrigerator are. For questions or service call Achieve Appliance Repair:


The compressor is both a motor and a pump, and it is need for circulation of refrigerant dispensed in the cooling system.
The compressor is an important part of a refrigerator. Homeowners should call on a professional company if the compressor is broken.


The refrigerator condenser is found on the back exterior panel of the appliance and is there to release the warmth collected within the refrigerator out into the surrounding air.


A evaporator is stored in the interior of the refrigerator where it absorbs warmth trapped inside of it, effectively reducing the interior temperature.

Right when an evaporator is not working, it’s time to call a professional. You should not wait too long.

Expansion Device

Liquid coolant is transferred through a capillary tube which works as an expansion device as it cools the gas inside, turning it into a liquid.


The thermostat regulates the current temperature within the refrigerator, starting the cooling cycle when it is needed.

A thermostat inside of a refrigerator is prone to breaking. Troubleshoot and call a repairman in Arlington for service the moment an issue happens.

How Does Refrigeration Work?

1. The moment the temperature within the refrigerator is higher than the set point sensors signal the refrigerator compressor to start, and then the next cooling cycle begins. The refrigerator collects the cool liquid refrigerant, then condenses and pressurizes the liquid, and raises the temperature, turning it into a gas.

2. The compressor unit pushes the heated gas in the direction of the condenser coils on the back of the appliance, at which point it comes in contact with warmer temperature in the kitchen and reverts back to a liquified form.

3. The cool liquified gas then continues on its trip towards the evaporator component, traveling through the many coils within the refrigerator and freezer compartment.

4. The coolant absorbs the heated air from inside the refrigerator, lowering the temperature down to the best set point.

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

Refrigeration is often found in several applications and appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By removing warmth from one place and then distributing it to elsewhere the continuous cycle of refrigeration will help cooling a home, creates a perfect storage space for perishable food, and helps with the manufacturing and storage of many different everyday products and goods.
