Parts of a Refrigerator

There aren’t too many houses that don’t feature a refrigerator inside the kitchen. It has been a must-own kitchen appliance for a lot of years. A household refrigerator stores your food and drinks at the optimal temperature, in order to prevent spoilage and limit harmful bacteria. The cycle of refrigeration works by moving the warmth from the interior of the refrigerator to the exterior, relying on principles of condensation and evaporation.

The standard parts of your refrigerator are below. For questions or service call Cherry Appliance Repair:


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


A condenser is attached on the rear outside wall of the refrigerator and will help to emit the warmth built-up from within the refrigerator out to the air.


The refrigerator evaporator is located on the interior of the refrigerator where absorbs the heat contained within it, effectively lowering the interior temperature.

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

Expansion Device

Liquid refrigerant is carried through a capillary tube which works as an expansion device as it cools the gas inside, thereby turning it back into liquid.


The thermostat exists to regulate the temperature throughout the refrigerator, engaging the cooling period when necessary.

A thermostat inside of a refrigerator is prone to malfunction. Troubleshoot and hire a contractor in Virginia for service right when an issue happens.

How Does Refrigeration Work?

1. Once the temperature inside a refrigerator is higher than the set point sensors alert the refrigerator compressor to begin, and the cooling period begins. The appliance attracts the cold liquified refrigerant, then condenses and pressurizes it, and increases the temperature, in order to turn it into a gas form.

2. The compressor unit directs the warm gas in the direction of the condenser coils located on the outside of the unit, at which point it comes into contact with the lower temperature in the room and reverts to a liquid state.

3. The cool liquified gas then continues on its trip to the evaporator, finding its way through the many coils on the interior of the refrigerator and top freezer.

4. The liquid then absorbs the hot air from inside the appliance, returning the temperature until it has reached the best set point.

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

Refrigeration technology is found in quite a few applications and appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By contracting heat from one area and distributing it to another the continuous cycle of refrigeration aids in cooling your house, creates a optimal storage space for perishable food, and also helps with manufacturing and storage of many different products and goods.
