Parts of a Refrigerator

You will not find many homes that do not have a refrigerator in the kitchen. It’s been a standard appliance for a lot of years. A residential refrigerator can store food and drinks at the optimal temperature, to stop rotting and slow down bacteria. The cycle of refrigeration works by distributing the warmth from the inside of the refrigerator to the outside, by using principles of condensation and evaporation.

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


The refrigerator compressor is a combo of a motor and a pump, and it’s necessary for the circulation of refrigerant in the system.
A compressor is an important part of a refrigerator. Homeowners should call on a professional company if the compressor is broken.


A condenser is attached on the back outside panel of the appliance and is there to emit the warmth built-up from within the refrigerator out in the air.


A evaporator is installed in the interior of the refrigerator where it absorbs heat contained inside of it, thereby reducing the interior temperature.

Right when an evaporator isn’t working, it is time to hire a professional. Do not wait too long.

Expansion Device

Liquid refrigerant is carried within a capillary tube which works as an expansion tool to cool the gas inside, thereby turning the gas into a liquid.


A thermostat regulates the temperature inside a refrigerator, starting the cooling cycle as it is required.

The thermostat inside of a refrigerator is prone to problems. Troubleshoot and hire a repairman in CITY for service right after a problem occurs.

How Does Refrigeration Work?

1. The moment the temperature inside a refrigerator goes above the set point sensors signal the refrigerator compressor to start, and then the cooling period starts. The unit collects the cool liquified refrigerant, condenses and pressurizes the refrigerant, and increases the temperature, turning it into a gas.

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

3. The cool liquid then continues its journey towards the evaporator component, traveling through the many coils within the appliance and freezer.

4. The refrigerant then absorbs the heated air from the interior of the refrigerator, thereby lowering the temperature back to the desired final point.

5. The refrigerant will evaporate, and will turn back into a gas state, and then returns to the compressor unit in order to then continue the cycle.

Refrigeration technology is often found in several applications and household appliances, this includes heat pumps, air conditioners, refrigerators and freezers. By removing heat from one place and transferring it to somewhere else the continuous cycle of refrigeration contributes in cooling your house, provides a optimal environment for food that is perishable, and helps with manufacturing and storage of a number of different common products and goods.
