Parts of a Refrigerator

There aren’t many homes that don’t feature a refrigerator inside the kitchen. It’s been a must-own household appliance for a lot of years now. A residential refrigerator stores your food at the optimal temperature, in order to eliminate rotting and stop the growth of harmful bacteria. The cycle of refrigeration works by moving the warmth from the inside of the appliance to the exterior, using principles of evaporation and condensation.

The components of a refrigerator are. For questions or service call Renew Appliance Repair:


A refrigerator compressor is both a motor and a pump, and it’s need for the circulation of refrigerant in the system.
The compressor is an integral piece of a refrigerator. You should enlist a professional company if the compressor isn’t working.


The condenser is attached on the back outside wall of the appliance and will help to release the warmth collected from within the refrigerator out in the air.


The refrigerator evaporator is located in the interior of the refrigerator where absorbs warmth trapped within it, thereby lowering the temperature inside the appliance.

The moment an evaporator is not working, it’s time to call a professional. Do not wait too long.

Expansion Device

Liquified refrigerant is directed through a capillary tube that works as an expansion tool to cool the gas inside, transforming the gas into liquid.


A refrigerator thermostat regulates the temperature inside the refrigerator, engaging the cooling cycle when it is required.

The thermostat in a refrigerator is often prone to malfunction. Troubleshoot and call a contractor in Bowie for repair the moment an issue occurs.

How Does Refrigeration Work?

1. The moment the temperature in the interior of a refrigerator is higher than the set point sensors alert the refrigerator compressor to start, and then the cool down begins. The unit draws in the cool liquid refrigerant, then pressurizes and condenses it, and raises the temperature, turning it into a gas.

2. The compressor guides the heated gas towards the condenser coils located on the rear of the unit, where it comes in contact with the lower air temperature in the room and transforms back to a liquified form.

3. The cooled liquid continues its trip towards the evaporator component, traveling through the many coils in the inside of the appliance and top freezer compartment.

4. The liquid then absorbs the hot air from inside the refrigerator, thereby cooling the temperature down to the desired set point.

5. The coolant will evaporate, and will return back to a gas, and returns to the compressor unit so it can then continue the cooling cycle.

Refrigeration is often used in quite a few applications and large appliances, including heat pumps, AC units, refrigerators and freezers. By contracting warmth from a single location and distributing it to another the continuous cycle of refrigeration contributes in cooling a home, creates a optimal environment for perishable food, and also helps with manufacturing and storage of a lot of different common products and materials.
