Parts of a Refrigerator

You won’t find many houses that do not feature a refrigerator inside the kitchen. It has been a must-own kitchen appliance for a lot of years now. A refrigerator stores your food at the optimal temperature, in order to stop spoilage and stop the growth of bacteria. The concept of refrigeration starts by transferring the warmth from the interior of the appliance to the outside, by using principles of condensation and evaporation.

The primary components of a refrigerator are below. For questions or service call Lee Appliance Repair:


A refrigerator compressor is both a motor and pump, and it’s responsible for the circulation of refrigerant in the system.
A compressor is an integral part of a refrigerator. Homeowners should hire a professional company if the compressor is broken.


A refrigerator condenser is attached on the rear exterior wall of the refrigerator and helps to disperse the warmth collected from within the refrigerator out into the air.


A evaporator is housed in the interior of the refrigerator where absorbs warmth contained within it, effectively reducing the interior temperature.

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

Expansion Device

Liquid refrigerant is carried within a capillary tube that works as an expansion tool to cool the gas inside, thereby transforming it into a liquid.


The thermostat helps regulate the current temperature throughout a refrigerator, engaging a new cooling cycle as necessary.

The thermostat inside of a refrigerator is very prone to problems. Troubleshoot and hire a repairman in Sioux City for service the moment an issue happens.

How Does Refrigeration Work?

1. The moment the temperature within the refrigerator goes above the set point sensors signal the compressor to start, and then the next cooling cycle starts. The refrigerator attracts the cool liquified refrigerant, then pressurizes and condenses the refrigerant, and raises the temperature, turning it into a gas form.

2. The refrigerator compressor unit directs the heated gas in the direction of the condenser coils located on the exterior of the unit, at which point it comes into contact with the lower temperature in the home and transforms to a liquid state.

3. The cooled liquified gas continues its trip to the evaporator component, traveling through the coils on the interior of the refrigerator and freezer section.

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

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

Refrigeration technology is found in several applications and large appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By contracting warmth from one place and moving it to another the continuous cycle of refrigeration aids in cooling your home, provides a optimal storage space for perishable food, and helps with the manufacturing and storage of a number of different products and materials.
