Parts of a Refrigerator

You will not find many houses that do not feature a refrigerator in the kitchen. It has been a standard kitchen appliance for many years. A residential refrigerator stores food and drinks at the right temperature, to stop spoilage and slow down the growth of bacteria. The concept of refrigeration starts by distributing the warmth from the inside of the refrigerator to the exterior, by using the principles of evaporation and condensation.

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


A compressor is both a pump and a motor, and it is need for the circulation of refrigerant dispensed in the system.
A compressor is a very important piece of a refrigerator. Homeowners should call on a professional service if the compressor is broken.


A refrigerator condenser is attached on the rear exterior wall of the appliance and helps to disperse the warmth collected within the refrigerator then out in the surrounding air.


A evaporator is stored on the inside of the refrigerator where absorbs the warmth contained within it, thereby reducing the interior temperature.

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

Expansion Device

Liquified coolant is transferred through a capillary tube that acts as an expansion device to cool the gas inside, thereby transforming the gas back into a liquid.


The refrigerator thermostat regulates the temperature in the interior of a refrigerator, starting the cooling period as needed.

The thermostat inside of a refrigerator is prone to breaking. Troubleshoot and hire a contractor in Florida for service right after an issue happens.

How Does Refrigeration Work?

1. The moment the temperature inside the refrigerator is above the set point sensors signal the refrigerator compressor to start, and the next cool down begins. The appliance draws in the cool liquid refrigerant, then condenses and pressurizes it, and increases the temperature, in order to turn it into a gas.

2. The compressor guides the warm gas towards the condenser coils on the exterior of the unit, where it comes in contact with the lower air temperature in the home and reverts back to a liquid form.

3. The cooled liquified gas then continues its trip to the refrigerator evaporator component, finding its way through the coils in the interior of the refrigerator and top freezer compartment.

4. The liquid absorbs the heated air from the interior of the appliance, thereby lowering the temperature back to the correct set point.

5. The coolant then evaporates, and turns back to a gas state, and then returns to the refrigerator compressor unit to then continue the cooling cycle.

Refrigeration is often found in several applications and large appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By removing warmth from one area and transferring it to another the cycle of refrigeration aids in cooling your home, provides a safe space for perishable food, and also helps with the manufacturing and storage of a lot of different products and materials.
