Parts of a Refrigerator

There are not many houses that don’t feature a refrigerator inside the kitchen. It’s been a must-own household appliance for a lot of years now. A residential refrigerator stores your food and drinks at the best temperature, to stop rotting and slow down bacteria. The process of refrigeration works by transferring the warmth from inside of the refrigerator to the outside, by using the principles of condensation and evaporation.

The primary parts of your refrigerator are below. For questions or service call Warner Appliance Repair:


A refrigerator compressor is a combination of a motor and a pump, and it is need for the circulation of refrigerant throughout the system.
A compressor is a very important piece of a refrigerator. Homeowners should call on a professional service if the compressor stops working.


The condenser is located on the back outside panel of the refrigerator and will help to emit the warmth absorbed from within the refrigerator then out to the surrounding air.


A evaporator is installed in the interior of the refrigerator where absorbs the warmth contained inside of it, thereby lowering the interior temperature.

The moment an evaporator is not working, it’s time to enlist a professional. Do not wait too long.

Expansion Device

Liquid refrigerant is directed within a capillary tube which acts as an expansion tool as it cools the gas inside, thereby transforming the gas into liquid.


A thermostat regulates the temperature inside a refrigerator, engaging the cooling cycle when it is required.

The thermostat in a refrigerator is prone to problems. Troubleshoot and hire a repairman in CITY for repair right after a problem happens.

How Does Refrigeration Work?

1. The moment the temperature in the interior of a refrigerator is higher than the set point sensors alert the compressor to begin, and the next cooling period starts. The refrigerator draws in the cold liquid refrigerant, then pressurizes and condenses it, and increases the temperature, so it can turn into a gas.

2. The refrigerator compressor pushes the warm gas in the direction of the refrigerator condenser coils located on the rear of the refrigerator, at which point it comes into contact with the lower temperature in the room and transforms to a liquified form.

3. The cooled refrigerant continues its trip to the evaporator, pushing through the many coils within the appliance and top freezer.

4. The refrigerant then absorbs the heated air from inside the refrigerator, returning the temperature back to the desired final point.

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

Refrigeration technology is often used in many applications and large appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By contracting heat from a single area and moving it to another the cycle of refrigeration will help cooling a home, provides a safe space for food that is perishable, and helps with manufacturing and storage of a number of different products and materials.
