Parts of a Refrigerator

There aren’t many houses that don’t have a refrigerator in the kitchen. It’s been a standard appliance for many years. A refrigerator can store your food and drinks at the best temperature, in order to stop spoilage and stop the growth of bacteria. The cycle of refrigeration works by distributing the warmth from the interior of the unit to the exterior, using the principles of evaporation and condensation.

The parts of your refrigerator are below. For questions or service call Waukegan Appliance Repair:


A refrigerator compressor is both a pump and a motor, and it is need for circulation of refrigerant in the cooling system.
The compressor is a very important part of a refrigerator. You should hire a professional company if the compressor isn’t working.


The condenser is found on the back exterior wall of the refrigerator and helps to disperse the heat absorbed from inside the refrigerator out to the surrounding air.


The evaporator is housed on the inside of the refrigerator where it absorbs warmth trapped inside of it, effectively reducing the temperature inside the refrigerator.

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

Expansion Device

Liquid coolant is carried within a capillary tube which acts as an expansion device as it cools the gas, transforming the gas into a liquid.


The refrigerator thermostat exists to regulate the current temperature in the interior of the refrigerator, engaging the cooling cycle as it is required.

A thermostat inside of a refrigerator is prone to malfunction. Troubleshoot and call a technician in Waukegan for repair right after a problem happens.

How Does Refrigeration Work?

1. Once the temperature inside a refrigerator rises above the set point sensors alert the compressor to start, and then the next cooling cycle starts. The appliance collects the cool liquified refrigerant, pressurizes and condenses the refrigerant, and increases the temperature, so it can turn into a gas form.

2. The compressor pushes the warm gas in the direction of the condenser coils on the exterior of the appliance, where it comes into contact with warmer air temperature in the kitchen and returns to a liquified form.

3. The cool liquified gas continues its journey towards the refrigerator evaporator, traveling through the many coils in the inside of the appliance and freezer compartment.

4. The refrigerant then absorbs the hot air from inside the appliance, cooling the temperature until it has reached the best final point.

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

Refrigeration technology is found in many applications and large appliances, this includes heat pumps, AC units, refrigerators and freezers. By extracting warmth from one location and moving it to another the continuous cycle of refrigeration will help cooling a house, provides a optimal environment for perishable food, and helps with the manufacturing and storage of a lot of different common products and materials.
