Parts of a Refrigerator

You won’t find too many houses that do not feature a refrigerator inside the kitchen. It has been a must-have kitchen appliance for a lot of years now. A residential refrigerator can store food at the optimal temperature, to prevent spoiling and limit bacteria. The cycle of refrigeration starts by transferring the warmth from the interior of the appliance to the outside, by using principles of condensation and evaporation.

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


The refrigerator compressor is both a motor and pump, and it’s need for circulation of refrigerant dispersed in the system.
The compressor is an integral part of a refrigerator. You should call a professional company if the compressor stops working.


The condenser is attached on the rear outside wall of the appliance and will help to emit the warmth built-up within the refrigerator out to the surrounding air.


A evaporator is housed in the interior of the refrigerator where absorbs warmth held within it, effectively lowering the temperature inside the unit.

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

Expansion Device

Liquid coolant is transported within a capillary tube which works as an expansion tool to cool the gas, turning the gas into liquid.


A refrigerator thermostat exists to regulate the temperature throughout a refrigerator, engaging the cooling period as necessary.

A thermostat inside of a refrigerator is very prone to breaking. Troubleshoot and call a repairman in Garland for repair the moment an issue happens.

How Does Refrigeration Work?

1. The moment the temperature inside a refrigerator is higher than the set point sensors notify the refrigerator compressor to engage, and the cooling period begins. The unit draws in the cold liquid refrigerant, condenses and pressurizes the liquid, and increases the temperature, turning it into a gas.

2. The compressor guides the hot gas in the direction of the condenser coils located on the rear of the appliance, at which point it comes in contact with warmer air temperature in the kitchen and reverts back to a liquified form.

3. The cooled refrigerant continues on its trip to the evaporator, traveling through the many coils within the appliance and freezer section.

4. The refrigerant absorbs the hot air from inside the appliance, cooling the temperature back to the correct final point.

5. The coolant evaporates, and will return back into a gas state, and then returns to the refrigerator compressor in order to continue the cycle.

Refrigeration technology is often used in many applications and large appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By removing warmth from a single location and moving it to another the cycle of refrigeration helps cooling your house, creates a perfect space for perishable food, and also helps with manufacturing and storage of several different products and goods.
