Parts of a Refrigerator

You will not find many houses that don’t have a refrigerator inside the kitchen. It’s been a standard appliance for many years now. A refrigerator will store your food and drinks at the optimal temperature, in order to stop spoilage and limit bacteria. The process of refrigeration works by moving the warmth from the interior of the appliance to the outside, by relying on the principles of condensation and evaporation.

The main components of your refrigerator are. For questions or service call Premiere Chicago Appliance Repair:


A compressor is both a motor and a pump, and it’s necessary for the circulation of refrigerant in the cooling system.
A compressor is a very important piece of a refrigerator. Homeowners should enlist a professional company if the compressor is broken.


The condenser is located on the back outside panel of the refrigerator and is there to release the heat absorbed from inside the refrigerator then out in the air.


The evaporator is attached in the inside of a refrigerator where it absorbs the heat trapped inside of it, effectively lowering the interior temperature.

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

Expansion Device

Liquid coolant is transported within a capillary tube which acts as an expansion tool as it cools the gas inside, turning the gas back into liquid.


A thermostat regulates the temperature throughout a refrigerator, starting the cooling cycle when appropriate.

The thermostat inside of a refrigerator is often prone to issues. Troubleshoot and call a repairman in Chicago for service right when a problem happens.

How Does Refrigeration Work?

1. Once the temperature inside a refrigerator is above the set point sensors signal the refrigerator compressor to start, and the cool down starts. The unit draws in the cold liquified refrigerant, then condenses and pressurizes it, and raises the temperature, turning it into a gas form.

2. The refrigerator compressor unit directs the heated gas towards the condenser coils on the back of the unit, where it comes in contact with warmer air temperature in the home and returns to a liquid state.

3. The cooled liquid continues on its journey to the refrigerator evaporator, pushing through the many coils in the inside of the refrigerator and freezer section.

4. The liquid absorbs the hot air from within the appliance, thereby returning the temperature until it has reached the correct final point.

5. The liquid will evaporate, and turns back into a gas, and then returns to the refrigerator compressor so it can continue the cycle.

Refrigeration is often found in several applications and household appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By contracting warmth from a single area and then moving it to somewhere else the continuous cycle of refrigeration helps cooling your house, creates a perfect space for perishable food, and also helps with the manufacturing and storage of many different products and goods.
