Parts of a Refrigerator

You won’t find many homes that don’t feature a refrigerator in the kitchen. It has been a must-own appliance for a lot of years. A residential refrigerator stores food and drinks at the right temperature, to stop spoilage and slow down harmful bacteria. The concept of refrigeration works by distributing the warmth from the inside of the appliance to the outside, by using the principles of evaporation and condensation.

The components of your refrigerator are below. For questions or service call Sterling Heights Appliance Repair HQ:


The refrigerator compressor is a combo of a pump and motor, and it’s necessary for the circulation of refrigerant throughout the cooling system.
The compressor is a very important piece of a refrigerator. Homeowners should call a professional service if the compressor isn’t working.


A refrigerator condenser is located on the rear exterior wall of the appliance and is there to emit the heat built-up inside the refrigerator out to the air.


The evaporator is installed in the inside of the refrigerator where it absorbs the heat trapped within it, effectively reducing the interior temperature.

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

Expansion Device

Liquified refrigerant is directed through a capillary tube that serves as an expansion tool to cool the gas, thereby turning the gas into a liquid.


A refrigerator thermostat helps regulate the current temperature inside a refrigerator, starting a new cooling cycle as it is needed.

The thermostat inside of a refrigerator is often prone to breaking. Troubleshoot and hire a contractor in Sterling Heights for repair right after a problem happens.

How Does Refrigeration Work?

1. The moment the temperature in the interior of a refrigerator goes higher than the set point sensors alert the refrigerator compressor to begin, and the cool down starts. The unit collects the cold liquified refrigerant, then pressurizes and condenses the refrigerant, and raises the temperature, in order to turn it into a gas form.

2. The refrigerator compressor unit guides the warm gas towards the condenser coils located on the back of the appliance, where it comes in contact with the lower temperature in the kitchen and returns to a liquid form.

3. The cool refrigerant continues its journey towards the refrigerator evaporator, pushing through the coils on the inside of the appliance and top freezer compartment.

4. The refrigerant absorbs the warm air from inside the appliance, returning the temperature until it has reached the desired final point.

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

Refrigeration is found in a number of applications and household appliances, this includes heat pumps, AC units, refrigerators and freezers. By contracting heat from a single area and then transferring it to a different one the cycle of refrigeration helps cooling your house, creates a perfect storage space for perishable food, and also helps with the manufacturing and storage of several different everyday products and materials.
