Parts of a Refrigerator

There aren’t many homes that do not have a refrigerator inside the kitchen. It’s been a standard household appliance for many years now. A refrigerator is able to store food and drinks at the optimal temperature, in order to prevent rotting and limit bacteria. The concept of refrigeration works by transferring the heat from the interior of the refrigerator to the outside, by using the principles of evaporation and condensation.

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


The compressor is both a pump and a motor, and it is responsible for the circulation of refrigerant in the cooling system.
The compressor is an important piece of a refrigerator. You should call a professional company if the compressor stops working.


The refrigerator condenser is located on the rear outside wall of the appliance and is there to emit the warmth absorbed within the refrigerator out into the surrounding air.


A evaporator is installed in the interior of a refrigerator where absorbs the heat trapped within it, effectively lowering the interior temperature.

Once the evaporator isn’t working, it’s time to hire a professional. Do not wait until it’s too late.

Expansion Device

Liquid coolant is carried through a capillary tube that works as an expansion device as it cools the gas, thereby transforming the gas into a liquid.


The thermostat will regulate the current temperature within the refrigerator, starting the cooling period as it is needed.

A thermostat in a refrigerator is very prone to issues. Troubleshoot and call a repairman in Albany for service right after a problem occurs.

How Does Refrigeration Work?

1. The moment the temperature inside the refrigerator rises higher than the set point sensors signal the refrigerator compressor to engage, and the cool down begins. The unit collects the cold liquid refrigerant, then pressurizes and condenses it, and raises the temperature, turning it into a gas.

2. The refrigerator compressor unit directs the hot gas towards the condenser coils located on the rear of the unit, where it comes into contact with warmer temperature in the home and transforms to a liquified form.

3. The cooled liquid continues on its journey towards the refrigerator evaporator component, pushing through the many coils within the refrigerator and top freezer.

4. The liquid then absorbs the warm air from the interior of the refrigerator, thereby cooling the temperature down to the correct final point.

5. The coolant then evaporates, and turns back into a gas, and returns to the compressor in order to continue the cycle.

Refrigeration is used in a number of applications and household appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By removing heat from a single place and then transferring it to elsewhere the cycle of refrigeration contributes in cooling your house, provides a perfect storage space for perishable food, and helps with manufacturing and storage of a lot of different products and goods.
