Parts of a Refrigerator

You won’t find many homes that don’t have a refrigerator inside the kitchen. It’s been a must-own appliance for a lot of years now. A refrigerator stores food and drinks at the best temperature, in order to prevent spoiling and stop harmful bacteria. The process of refrigeration works by distributing the warmth from inside of the refrigerator to the outside, by relying on principles of condensation and evaporation.

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


The compressor is a combo of a motor and pump, and it’s responsible for the circulation of refrigerant in the system.
The compressor is a very important piece of a refrigerator. Homeowners should hire a professional company if the compressor is no longer working.


The refrigerator condenser is found on the back exterior panel of the refrigerator and will help to release the warmth absorbed from inside the refrigerator out to the surrounding air.


A evaporator is located on the interior of a refrigerator where absorbs the warmth held inside of it, thereby reducing the temperature inside the refrigerator.

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

Expansion Device

Liquified coolant is transported through a capillary tube that works as an expansion device as it cools the gas, turning it into liquid.


The refrigerator thermostat regulates the temperature inside a refrigerator, beginning the cooling cycle when it is necessary.

The thermostat inside of a refrigerator is often prone to malfunction. Troubleshoot and call a repairman in California for service right after an issue happens.

How Does Refrigeration Work?

1. Once the temperature inside the refrigerator is above the set point sensors signal the refrigerator compressor to engage, and then the next cool down starts. The refrigerator collects the cold liquid refrigerant, pressurizes and condenses it, and raises the temperature, so it can turn into a gas.

2. The refrigerator compressor guides the heated gas towards the refrigerator condenser coils located on the outside of the appliance, at which point it comes into contact with the lower temperature in the room and transforms back to a liquid form.

3. The cool liquid then continues on its trip to the evaporator component, pushing through the many coils within the refrigerator and top freezer compartment.

4. The refrigerant then absorbs the hot air from inside the appliance, thereby cooling the temperature until it has reached the desired set point.

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

Refrigeration technology is used in a lot of applications and appliances, this includes heat pumps, air conditioners, refrigerators and freezers. By contracting warmth from one area and then relocating it to somewhere else the continuous cycle of refrigeration aids in cooling your home, provides a perfect storage space for perishable food, and helps with manufacturing and storage of many different common products and goods.
