Parts of a Refrigerator

There are not many homes that don’t feature a refrigerator in the kitchen. It has been a standard kitchen appliance for several years. A refrigerator is able to store food at the optimal temperature, to stop spoilage and limit the growth of bacteria. The process of refrigeration starts by moving the warmth from the inside of the appliance to the exterior, by relying on the principles of evaporation and condensation.

The main components of your refrigerator are below. For questions or service call Ward Appliance Repair:


The compressor is both a motor and a pump, and it’s necessary for the circulation of refrigerant throughout the cooling system.
A compressor is a very important part of a refrigerator. Homeowners should call on a professional company if the compressor is broken.


The refrigerator condenser is attached on the back exterior panel of the refrigerator and will help to release the heat collected within the refrigerator then out to the air.


The evaporator is located in the interior of the refrigerator where absorbs the warmth held inside of it, thereby reducing the interior temperature.

Right when an evaporator isn’t working, it’s time to enlist a professional. You should not wait until it’s too late.

Expansion Device

Liquified refrigerant is directed within a capillary tube that serves as an expansion device to cool the gas inside, thereby transforming it into a liquid.


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

A thermostat in a refrigerator is very prone to problems. Troubleshoot and call a contractor in Atlanta for service right after a problem occurs.

How Does Refrigeration Work?

1. Right when the temperature inside a refrigerator rises above the set point sensors alert the compressor to begin, and then the next cool down begins. The unit attracts the cold liquified refrigerant, then condenses and pressurizes it, and raises the temperature, so it can turn into a gas form.

2. The refrigerator compressor unit pushes the heated gas towards the condenser coils located on the outside of the unit, at which point it comes into contact with the lower air temperature in the room and transforms to a liquified state.

3. The cool liquified gas then continues on its journey towards the evaporator, pushing through the coils within the refrigerator and top freezer.

4. The coolant then absorbs the warm air from inside the appliance, thereby reducing the temperature until it has reached the optimal final point.

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

Refrigeration technology is used in several applications and large appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By contracting heat from a single place and then distributing it to another the cycle of refrigeration contributes in cooling a home, provides a perfect environment for perishable food, and also helps with the manufacturing and storage of a number of different everyday products and goods.
