Parts of a Refrigerator

You will not find too many homes that do not feature a refrigerator in the kitchen. It has been a must-have appliance for many years. A household refrigerator will store your food and drinks at the right temperature, in order to stop spoilage and slow down the growth of harmful bacteria. The process of refrigeration starts by transferring the warmth from the inside of the unit to the outside, using the principles of condensation and evaporation.

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


A compressor is both a pump and a motor, and it is responsible for the circulation of refrigerant in the cooling system.

The compressor is a very important part of a refrigerator. Homeowners should enlist a professional company if the compressor is not working.


The condenser is attached on the back outside wall of the appliance and helps to disperse the warmth absorbed inside the refrigerator then out to the surrounding air.


A evaporator is attached on the inside of a refrigerator where absorbs heat held inside of it, effectively reducing the temperature inside.

Once an evaporator is not working, it is time to hire a professional. You should not wait too long.

Expansion Device

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


The refrigerator thermostat will regulate the current temperature in the interior of the refrigerator, engaging the cooling period as necessary.

A thermostat inside of a refrigerator is often prone to problems. Troubleshoot and call a contractor in Rhode Island for service the moment an issue occurs.

How Does Refrigeration Work?

1. When the temperature in the interior of the refrigerator rises above the set point sensors notify the refrigerator compressor to engage, and then the next cool down begins. The unit collects the cold liquid refrigerant, then pressurizes and condenses it, and increases the temperature, turning it into a gas form.

2. The compressor unit guides the heated gas towards the condenser coils located on the exterior of the refrigerator, where it comes in contact with warmer air temperature in the room and transforms back to a liquid state.

3. The cooled liquid then continues its trip towards the refrigerator evaporator component, pushing through the many coils within the refrigerator and freezer.

4. The refrigerant absorbs the heated air from inside the appliance, lowering the temperature down to the optimal final point.

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

Refrigeration is found in a number of applications and large appliances, this includes heat pumps, air conditioners, refrigerators and residential freezers. By contracting warmth from one place and then distributing it to elsewhere the cycle of refrigeration aids in cooling a home, creates a perfect storage space for food that is perishable, and also helps with manufacturing and storage of a number of different everyday products and materials.
