Parts of a Refrigerator

You won’t find many houses that do not have a refrigerator in the kitchen. It has been a standard household appliance for several years now. A refrigerator stores your food at the best temperature, in order to prevent spoiling and slow down bacteria. The cycle of refrigeration starts by moving the warmth from the inside of the appliance to the outside, by using principles of evaporation and condensation.

The primary parts of your refrigerator are below. For questions or service call BRAND:


The compressor is both a pump and a motor, and it is responsible for circulation of refrigerant dispersed in the cooling system.
A compressor is an integral part of a refrigerator. Homeowners should call on a professional company if the compressor is broken.


The refrigerator condenser is located on the back outside panel of the refrigerator and is there to emit the warmth built-up from within the refrigerator out into the air.


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

Right when the evaporator is not working, it’s time to enlist a professional. You should not wait too long.

Expansion Device

Liquified refrigerant is transferred through a capillary tube which serves as an expansion tool to cool the gas inside, turning it into a liquid.


The thermostat helps regulate the current temperature throughout the refrigerator, beginning the cooling period as it is necessary.

The thermostat in a refrigerator is very prone to problems. Troubleshoot and call a repairman in Longmont for repair the moment a problem happens.

How Does Refrigeration Work?

1. When the temperature in the interior of the refrigerator rises higher than the set point sensors notify the compressor to begin, and the cool down starts. The appliance collects the cool liquified refrigerant, then condenses and pressurizes the liquid, and raises the temperature, so it can turn into a gas form.

2. The compressor pushes the hot gas towards the condenser coils on the outside of the refrigerator, where it comes in contact with the lower temperature in the room and reverts to a liquified state.

3. The cool refrigerant then continues its journey towards the evaporator, finding its way through the many coils within the appliance and freezer section.

4. The refrigerant absorbs the heated air from inside the refrigerator, thereby reducing the temperature until it has reached the desired final point.

5. The coolant then will evaporate, and will return back into a gas state, and returns to the compressor in order to continue the cooling cycle.

Refrigeration technology is used in a lot of applications and large appliances, including heat pumps, AC units, refrigerators and residential freezers. By contracting heat from one place and transferring it to a different one the cycle of refrigeration will help cooling your house, provides a perfect environment for food that is perishable, and helps with manufacturing and storage of a lot of different common products and goods.
