Parts of a Refrigerator

You won’t find many houses that don’t feature a refrigerator inside the kitchen. It has been a must-own appliance for a lot of years now. A residential refrigerator stores food and drinks at the right temperature, to reduce spoilage and limit harmful bacteria. The cycle of refrigeration works by transferring the warmth from the interior of the refrigerator to the outside, by relying on the principles of condensation and evaporation.

The main parts of a refrigerator are. For questions or service call A+ Aurora Appliance Repair:


The compressor is a combo of a motor and pump, and it’s responsible for circulation of refrigerant dispersed in the system.
The compressor is an important piece of a refrigerator. Homeowners should hire a professional company if the compressor stops working.


The refrigerator condenser is found on the back outside panel of the refrigerator and helps to emit the heat absorbed from within the refrigerator out into the surrounding air.


A refrigerator evaporator is installed on the inside of a refrigerator where it absorbs warmth trapped within it, effectively reducing the interior temperature.

The moment the evaporator stops working, it is time to hire a professional. Don’t wait until it’s too late.

Expansion Device

Liquid coolant is directed within a capillary tube that serves as an expansion tool as it cools the gas inside, transforming it into a liquid.


A refrigerator thermostat helps regulate the current temperature within a refrigerator, beginning a new cooling period as necessary.

A thermostat in a refrigerator is prone to breaking. Troubleshoot and hire a repairman in Aurora for service right when an issue occurs.

How Does Refrigeration Work?

1. Once the temperature inside a refrigerator rises above the set point sensors alert the refrigerator compressor to begin, and the next cool down begins. The appliance draws in the cold liquified refrigerant, then pressurizes and condenses the refrigerant, and raises the temperature, so it can turn into a gas form.

2. The refrigerator compressor unit pushes the heated gas towards the refrigerator condenser coils located on the back of the refrigerator, at which point it comes into contact with warmer temperature in the kitchen and reverts to a liquified form.

3. The cooled liquified gas then continues its trip towards the refrigerator evaporator component, making its way through the coils within the appliance and freezer section.

4. The coolant then absorbs the hot air from inside the refrigerator, thereby lowering the temperature until it has reached the desired final point.

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

Refrigeration technology is often used in several applications and household appliances, this includes heat pumps, air conditioners, refrigerators and residential freezers. By contracting heat from one location and distributing it to another the cycle of refrigeration will help cooling your home, creates a perfect storage space for perishable food, and helps with the manufacturing and storage of many different common products and materials.
