Parts of a Refrigerator

There are not too many houses that do not feature a refrigerator in the kitchen. It’s been a must-own household appliance for several years now. A residential refrigerator can store your food at the right temperature, to eliminate spoilage and limit the growth of harmful bacteria. The cycle of refrigeration works by moving the heat from the interior of the appliance to the exterior, by relying on principles of condensation and evaporation.

The parts of your refrigerator are. For questions or service call Anytime Ann Arbor Appliance Repair:


The refrigerator compressor is a combo of a pump and a motor, and it’s responsible for circulation of refrigerant in the system.
The compressor is an important part of a refrigerator. You should hire a professional company if the compressor is broken.


The condenser is located on the rear exterior wall of the appliance and will help to disperse the heat absorbed inside the refrigerator out in the surrounding air.


A evaporator is housed on the interior of the refrigerator where absorbs the warmth trapped within it, thereby lowering the interior temperature.

Right when an evaporator isn’t working, it is time to enlist a professional. Do not wait until it’s too late.

Expansion Device

Liquified coolant is directed through a capillary tube which works as an expansion device as it cools the gas, thereby turning it into liquid.


A thermostat helps regulate the temperature within the refrigerator, engaging a new cooling period when appropriate.

A thermostat inside of a refrigerator is often prone to breaking. Troubleshoot and call a repairman in Ann Arbor for service right when a problem happens.

How Does Refrigeration Work?

1. Once the temperature in the interior of the refrigerator is higher than the set point sensors signal the refrigerator compressor to start, and then the cool down starts. The refrigerator collects the cool liquid refrigerant, then condenses and pressurizes the refrigerant, and raises the temperature, in order to turn it into a gas.

2. The refrigerator compressor pushes the hot gas in the direction of the refrigerator condenser coils located on the outside of the unit, at which point it comes in contact with the lower air temperature in the kitchen and returns back to a liquid state.

3. The cooled refrigerant then continues its journey to the refrigerator evaporator component, making its way through the coils within the refrigerator and top freezer.

4. The coolant then absorbs the hot air from inside the appliance, thereby reducing the temperature until it has reached the optimal set point.

5. The liquid then evaporates, and will turn back into a gas state, and then returns to the refrigerator compressor so it can then continue the cycle.

Refrigeration technology is often used in quite a few applications and household appliances, including heat pumps, AC units, refrigerators and residential freezers. By extracting warmth from one place and then moving it to elsewhere the continuous cycle of refrigeration aids in cooling a house, provides a optimal environment for perishable food, and helps with manufacturing and storage of a number of different everyday products and materials.
