Parts of a Refrigerator

You will not find many houses that don’t feature a refrigerator in the kitchen. It’s been a must-have appliance for several years. A household refrigerator will store food and drinks at the optimal temperature, in order to stop spoilage and stop the growth of bacteria. The concept of refrigeration starts by moving the warmth from the inside of the unit to the outside, by relying on the principles of condensation and evaporation.

The primary parts of a refrigerator are. For questions or service call CRT Appliance Repair:


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


The refrigerator condenser is attached on the back outside panel of the refrigerator and helps to emit the warmth built-up inside the refrigerator then out into the surrounding air.


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

The moment an evaporator is not working, it’s time to call a professional. Do not wait too long.

Expansion Device

Liquid refrigerant is carried through a capillary tube that works as an expansion tool as it cools the gas inside, transforming the gas back into liquid.


A refrigerator thermostat helps regulate the temperature throughout a refrigerator, starting the cooling cycle when appropriate.

A thermostat inside of a refrigerator is very prone to problems. Troubleshoot and hire a repairman in CITY for repair the moment an issue happens.

How Does Refrigeration Work?

1. The moment the temperature in the interior of a refrigerator is above the set point sensors notify the refrigerator compressor to engage, and the next cool down starts. The unit collects the cold liquified refrigerant, pressurizes and condenses it, and increases the temperature, in order to turn it into a gas form.

2. The refrigerator compressor guides the hot gas towards the refrigerator condenser coils on the back of the refrigerator, where it comes into contact with the lower temperature in the kitchen and reverts to a liquid form.

3. The cooled liquid continues on its journey to the evaporator, pushing through the coils within the refrigerator and top freezer.

4. The liquid then absorbs the heated air from within the appliance, thereby lowering the temperature down to the best set point.

5. The refrigerant then will evaporate, and will return back to a gas state, and returns to the compressor unit to then continue the cycle.

Refrigeration technology is used in quite a few applications and household appliances, this includes heat pumps, air conditioners, refrigerators and residential freezers. By contracting heat from one place and then transferring it to somewhere else the continuous cycle of refrigeration will help cooling your house, creates a perfect space for perishable food, and also helps with the manufacturing and storage of several different everyday products and goods.
