Parts of a Refrigerator

There are not too many houses that do not have a refrigerator in the kitchen. It’s been a must-own appliance for a lot of years. A household refrigerator is able to store your food at the right temperature, in order to eliminate spoiling and limit the growth of harmful bacteria. The process of refrigeration works by transferring the heat from the inside of the appliance to the outside, relying on principles of condensation and evaporation.

The main parts of your refrigerator are. For questions or service call Triumph Appliance Repair:


A compressor is both a pump and a motor, and it is responsible for the circulation of refrigerant in the system.
A compressor is a very important part of a refrigerator. You should call a professional service if the compressor stops working.


A refrigerator condenser is attached on the back exterior wall of the refrigerator and helps to disperse the warmth built-up from inside the refrigerator then out to the air.


A evaporator is stored on the interior of the refrigerator where absorbs heat contained inside of it, effectively reducing the interior temperature.

The moment the evaporator is not working, it is time to enlist a professional. Do not wait too long.

Expansion Device

Liquified coolant is directed within a capillary tube that acts as an expansion tool as it cools the gas, thereby transforming the gas into a liquid.


The thermostat exists to regulate the current temperature inside the refrigerator, starting the cooling period as required.

The thermostat inside of a refrigerator is prone to problems. Troubleshoot and hire a contractor in White Plains for service the moment a problem happens.

How Does Refrigeration Work?

1. Right when the temperature within the refrigerator is above the set point sensors alert the compressor to engage, and then the cooling cycle begins. The unit attracts the cold liquified refrigerant, condenses and pressurizes the refrigerant, and increases the temperature, so it can turn into a gas.

2. The compressor guides the heated gas towards the refrigerator condenser coils on the rear of the unit, at which point it comes in contact with warmer air temperature in the room and returns back to a liquid form.

3. The cool liquid continues its journey towards the evaporator component, making its way through the many coils on the inside of the appliance and top freezer.

4. The liquid then absorbs the warm air from within the refrigerator, thereby lowering the temperature until it has reached the desired set point.

5. The liquid then evaporates, and will return back to a gas form, and returns to the compressor so it can continue the cycle.

Refrigeration is used in quite a few applications and appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By removing heat from a single location and moving it to elsewhere the cycle of refrigeration helps cooling your house, provides a safe storage space for perishable food, and also helps with the manufacturing and storage of a number of different common products and goods.
