Parts of a Refrigerator

There are not many houses that do not have a refrigerator in the kitchen. It’s been a standard appliance for a lot of years now. A residential refrigerator is able to store your food at the optimal temperature, in order to eliminate spoiling and stop the growth of bacteria. The cycle of refrigeration starts by transferring the warmth from the interior of the refrigerator to the outside, relying on the principles of condensation and evaporation.

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


A refrigerator compressor is both a motor and a pump, and it’s necessary for circulation of refrigerant in the cooling system.
A compressor is an integral part of a refrigerator. You should enlist a professional service if the compressor is not working.


A condenser is attached on the rear exterior wall of the refrigerator and helps to disperse the heat built-up from inside the refrigerator out in the air.


The evaporator is located in the interior of a refrigerator where it absorbs the warmth held within it, effectively lowering the temperature inside the unit.

Once the evaporator is not working, it’s time to hire a professional. Don’t wait too long.

Expansion Device

Liquid coolant is carried through a capillary tube which serves as an expansion device to cool the gas inside, thereby turning it back into liquid.


A refrigerator thermostat will regulate the temperature within the refrigerator, engaging the cooling cycle as appropriate.

The thermostat in a refrigerator is often prone to problems. Troubleshoot and call a technician in Greeley for repair right when an issue happens.

How Does Refrigeration Work?

1. Once the temperature inside the refrigerator rises above the set point sensors notify the refrigerator compressor to start, and then the next cool down starts. The unit draws in the cold liquid refrigerant, then pressurizes and condenses it, and increases the temperature, in order to turn it into a gas form.

2. The compressor directs the hot gas towards the condenser coils located on the exterior of the appliance, where it comes into contact with warmer temperature in the kitchen and transforms back to a liquified form.

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

4. The coolant absorbs the heated air from within the appliance, reducing the temperature until it has reached the desired set point.

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

Refrigeration is found in a number of applications and appliances, including heat pumps, AC units, refrigerators and residential freezers. By removing heat from a single place and relocating it to a different one the cycle of refrigeration contributes in cooling a house, creates a perfect space for perishable food, and helps with the manufacturing and storage of several different products and materials.
