Parts of a Refrigerator

You will not find too many homes that don’t have a refrigerator inside the kitchen. It’s been a must-have appliance for many years. A household refrigerator stores your food and drinks at the right temperature, in order to reduce spoiling and limit the growth of bacteria. The cycle of refrigeration starts by distributing the heat from the interior of the appliance to the outside, by using the principles of evaporation and condensation.

The standard components of your refrigerator are below. For questions or service call J&J Jackson Appliance Repair:


The compressor is a combo of a motor and a pump, and it’s responsible for the circulation of refrigerant in the cooling system.
The compressor is a very important piece of a refrigerator. You should enlist a professional service if the compressor is no longer working.


A refrigerator condenser is found on the rear exterior wall of the appliance and will help to release the warmth absorbed inside the refrigerator then out into the surrounding air.


A evaporator is housed on the interior of a refrigerator where it absorbs warmth trapped inside of it, effectively lowering the temperature inside.

The moment the evaporator stops working, it is time to hire a professional. You should not wait too long.

Expansion Device

Liquified coolant is transferred within a capillary tube which serves as an expansion device as it cools the gas inside, thereby transforming it into a liquid.


The refrigerator thermostat regulates the temperature within the refrigerator, beginning the cooling cycle as appropriate.

A thermostat inside of a refrigerator is prone to malfunction. Troubleshoot and hire a repairman in Jackson for service the moment a problem occurs.

How Does Refrigeration Work?

1. Once the temperature in the interior of the refrigerator rises higher than the set point sensors alert the compressor to start, and then the cool down starts. The unit collects the cool liquified refrigerant, then condenses and pressurizes the liquid, and raises the temperature, in order to turn it into a gas form.

2. The compressor unit directs the heated gas towards the condenser coils on the rear of the appliance, where it comes into contact with the lower temperature in the kitchen and returns back to a liquid state.

3. The cool refrigerant continues on its journey to the refrigerator evaporator component, pushing through the coils in the interior of the refrigerator and freezer section.

4. The coolant then absorbs the heated air from the interior of the appliance, thereby cooling the temperature until it has reached the correct set point.

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

Refrigeration is used in a number of applications and large appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By removing heat from one place and then distributing it to somewhere else the cycle of refrigeration will help cooling your home, provides a perfect space for perishable food, and helps with the manufacturing and storage of many different products and goods.
