Parts of a Refrigerator

There are not many homes that don’t feature a refrigerator inside the kitchen. It’s been a standard household appliance for several years now. A refrigerator is able to store your food at the best temperature, in order to eliminate spoilage and limit the growth of bacteria. The concept of refrigeration starts by distributing the warmth from inside of the refrigerator to the exterior, using principles of evaporation and condensation.

The primary parts of your refrigerator are. For questions or service call Gibson Appliance Repair:


A refrigerator compressor is both a motor and pump, and it’s necessary for circulation of refrigerant in the cooling system.
A compressor is an important part of a refrigerator. Homeowners should call a professional service if the compressor is broken.


The condenser is located on the back exterior panel of the appliance and is there to release the warmth collected from within the refrigerator then out in the surrounding air.


The refrigerator evaporator is attached in the interior of a refrigerator where absorbs warmth held within it, thereby reducing the interior temperature.

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

Expansion Device

Liquified refrigerant is carried within a capillary tube that works as an expansion tool as it cools the gas, turning the gas into liquid.


A refrigerator thermostat helps regulate the current temperature within the refrigerator, beginning the cooling period as it is appropriate.

A thermostat in a refrigerator is prone to problems. Troubleshoot and hire a technician in CITY for service right after a problem happens.

How Does Refrigeration Work?

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

2. The compressor pushes the hot gas in the direction of the condenser coils on the rear of the unit, where it comes in contact with the lower air temperature in the room and reverts to a liquified state.

3. The cooled refrigerant continues its journey towards the refrigerator evaporator, traveling through the many coils within the appliance and freezer.

4. The coolant absorbs the warm air from inside the appliance, thereby returning the temperature back to the correct set point.

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

Refrigeration is used in many applications and large appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By removing heat from one area and then relocating it to another the cycle of refrigeration will help cooling your home, creates a safe space for perishable food, and also helps with the manufacturing and storage of a lot of different everyday products and goods.
