Parts of a Refrigerator

You will not find too many houses that do not have a refrigerator inside the kitchen. It’s been a must-have kitchen appliance for many years. A refrigerator stores food at the right temperature, in order to stop spoilage and stop the growth of bacteria. The process of refrigeration starts by transferring the heat from inside of the unit to the exterior, using principles of evaporation and condensation.

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


A refrigerator compressor is both a motor and a pump, and it is need for circulation of refrigerant throughout the cooling system.

The compressor is a very important part of a refrigerator. Homeowners should enlist a professional service if the compressor isn’t working.


A condenser is attached on the rear exterior wall of the refrigerator and helps to disperse the warmth collected inside the refrigerator out into the surrounding air.


A refrigerator evaporator is installed in the interior of the refrigerator where it absorbs heat trapped inside of it, thereby lowering the temperature inside.

The moment an evaporator stops working, it is time to find a professional. You should not wait until it’s too late.

Expansion Device

Liquified coolant is directed through a capillary tube that acts as an expansion tool as it cools the gas inside, thereby turning the gas back into a liquid.


A refrigerator thermostat regulates the current temperature in the interior of the refrigerator, starting a new cooling period when it is needed.

A thermostat inside of a refrigerator is very prone to issues. Troubleshoot and call a repairman in CITY for repair the moment a problem happens.

How Does Refrigeration Work?

1. Once the temperature within a refrigerator goes above the set point sensors alert the refrigerator compressor to engage, and then the cool down starts. The unit collects the cold liquified refrigerant, condenses and pressurizes it, and raises the temperature, so it can turn into a gas form.

2. The compressor guides the hot gas in the direction of the condenser coils on the rear of the appliance, at which point it comes in contact with the lower air temperature in the kitchen and reverts back to a liquified state.

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

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

5. The liquid will evaporate, and will return back into a gas state, and returns to the refrigerator compressor unit in order to continue the cooling cycle.

Refrigeration is often found in quite a few applications and household appliances, this includes heat pumps, air conditioners, refrigerators and residential freezers. By extracting heat from one place and transferring it to somewhere else the cycle of refrigeration contributes in cooling a home, provides a optimal environment for food that is perishable, and also helps with the manufacturing and storage of a number of different everyday products and materials.
