Parts of a Refrigerator

There are not too many houses that don’t feature a refrigerator in the kitchen. It has been a must-own appliance for many years. A refrigerator is able to store your food at the right temperature, to prevent rotting and limit the growth of harmful bacteria. The concept of refrigeration starts by moving the warmth from the inside of the appliance to the exterior, by relying on principles of evaporation and condensation.

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


The compressor is a combo of a motor and a pump, and it is necessary for circulation of refrigerant throughout the cooling system.

The compressor is a very important piece of a refrigerator. You should hire a professional service if the compressor is not working.


A condenser is located on the back exterior wall of the refrigerator and is there to release the warmth collected within the refrigerator then out to the surrounding air.


The refrigerator evaporator is attached on the interior of a refrigerator where it absorbs heat trapped inside of it, thereby reducing the interior temperature.

Once the evaporator isn’t working, it is time to find a professional. You should not wait too long.

Expansion Device

Liquid refrigerant is directed through a capillary tube which works as an expansion device as it cools the gas inside, transforming it into liquid.


The thermostat helps regulate the current temperature in the interior of the refrigerator, engaging a new cooling cycle when needed.

The thermostat in a refrigerator is very prone to problems. Troubleshoot and call a technician in Missouri for repair the moment an issue occurs.

How Does Refrigeration Work?

1. When the temperature in the interior of a refrigerator goes higher than the set point sensors signal the compressor to engage, and then the next cooling period starts. The unit attracts the cold liquid refrigerant, then pressurizes and condenses the refrigerant, and raises the temperature, turning it into a gas form.

2. The refrigerator compressor unit guides the hot gas towards the condenser coils on the rear of the appliance, at which point it comes into contact with warmer air temperature in the room and transforms to a liquified state.

3. The cooled refrigerant continues its journey to the refrigerator evaporator, traveling through the many coils on the interior of the refrigerator and freezer compartment.

4. The coolant then absorbs the hot air from the interior of the appliance, reducing the temperature until it has reached the correct set point.

5. The coolant will evaporate, and turns back into a gas state, and returns to the compressor to continue the cooling cycle.

Refrigeration is found in many applications and household appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By removing warmth from a single place and moving it to somewhere else the cycle of refrigeration aids in cooling your home, creates a safe environment for perishable food, and also helps with the manufacturing and storage of a number of different products and goods.
