Parts of a Refrigerator

There are not too many houses that don’t have a refrigerator in the kitchen. It’s been a standard household appliance for many years now. A refrigerator can store your food and drinks at the best temperature, in order to stop spoiling and slow down bacteria. The process of refrigeration starts by moving the warmth from the interior of the appliance to the exterior, using principles of condensation and evaporation.

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


The refrigerator compressor is a combination of a pump and a motor, and it’s responsible for the circulation of refrigerant dispensed in the system.
A compressor is an important piece of a refrigerator. Homeowners should call a professional service if the compressor is broken.


The condenser is located on the back outside panel of the appliance and will help to emit the warmth absorbed from inside the refrigerator out in the air.


The evaporator is attached in the interior of the refrigerator where it absorbs warmth trapped inside of it, effectively reducing the interior temperature.

Once the evaporator is not working, it’s time to call a professional. You should not wait too long.

Expansion Device

Liquid refrigerant is carried through a capillary tube that acts as an expansion device as it cools the gas inside, transforming it into liquid.


The thermostat regulates the current temperature in the interior of the refrigerator, starting the cooling period when appropriate.

A thermostat inside of a refrigerator is often prone to issues. Troubleshoot and call a technician in Bryan for repair the moment a problem occurs.

How Does Refrigeration Work?

1. When the temperature inside a refrigerator is higher than the set point sensors notify the compressor to begin, and the cooling period begins. The unit attracts the cold liquid refrigerant, pressurizes and condenses it, and raises the temperature, so it can turn into a gas.

2. The refrigerator compressor unit directs the heated gas towards the condenser coils located on the back of the refrigerator, at which point it comes into contact with the lower temperature in the home and returns to a liquified state.

3. The cool liquified gas then continues its trip to the evaporator component, pushing through the coils in the inside of the appliance and freezer compartment.

4. The refrigerant absorbs the warm air from within the appliance, cooling the temperature back to the best final point.

5. The liquid will evaporate, and will return back to a gas, and then returns to the compressor unit in order to then continue the cycle.

Refrigeration technology is used in a number of applications and large appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By extracting heat from one area and then relocating it to elsewhere the continuous cycle of refrigeration helps cooling a home, creates a perfect environment for food that is perishable, and also helps with manufacturing and storage of several different everyday products and goods.
