Parts of a Refrigerator

There are not many houses that do not have a refrigerator in the kitchen. It’s been a must-have kitchen appliance for several years. A household refrigerator will store food and drinks at the best temperature, in order to prevent rotting and limit the growth of harmful bacteria. The concept of refrigeration works by distributing the heat from the interior of the appliance to the outside, relying on principles of condensation and evaporation.

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


The refrigerator compressor is a combination of a motor and pump, and it’s need for circulation of refrigerant in the cooling system.
A compressor is a very important part of a refrigerator. You should enlist a professional company if the compressor is broken.


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


The refrigerator evaporator is stored on the inside of the refrigerator where it absorbs the heat trapped within it, effectively reducing the interior temperature.

Right when an evaporator isn’t working, it is time to hire a professional. Don’t wait until it’s too late.

Expansion Device

Liquid coolant is transported through a capillary tube that acts as an expansion tool to cool the gas, thereby transforming the gas back into liquid.


The refrigerator thermostat regulates the current temperature inside a refrigerator, beginning the cooling cycle as it is needed.

The thermostat in a refrigerator is often prone to issues. Troubleshoot and hire a repairman in CITY for service right after an issue happens.

How Does Refrigeration Work?

1. When the temperature in the interior of the refrigerator is above the set point sensors signal the refrigerator compressor to engage, and then the cooling cycle starts. The refrigerator collects the cool liquid refrigerant, then pressurizes and condenses it, and raises the temperature, turning it into a gas form.

2. The refrigerator compressor pushes the hot gas towards the condenser coils located on the exterior of the appliance, at which point it comes into contact with warmer air temperature in the kitchen and reverts back to a liquified form.

3. The cool refrigerant continues on its journey to the evaporator component, finding its way through the coils within the refrigerator and top freezer section.

4. The refrigerant then absorbs the heated air from inside the refrigerator, thereby cooling the temperature down to the desired final point.

5. The refrigerant then evaporates, and will turn back to a gas form, and then returns to the compressor unit in order to continue the cooling cycle.

Refrigeration is often used in a number of applications and household appliances, including heat pumps, AC units, refrigerators and freezers. By extracting warmth from a single place and distributing it to somewhere else the cycle of refrigeration helps cooling your house, provides a perfect space for food that is perishable, and also helps with manufacturing and storage of a number of different everyday products and goods.
