Parts of a Refrigerator

You will not find too many houses that do not feature a refrigerator inside the kitchen. It’s been a standard household appliance for many years. A refrigerator can store food and drinks at the optimal temperature, in order to stop spoilage and stop the growth of harmful bacteria. The cycle of refrigeration starts by transferring the heat from the interior of the refrigerator to the outside, relying on principles of evaporation and condensation.

The primary components of a refrigerator are below. For questions or service call Jacobs Appliance Repair:


The compressor is both a motor and pump, and it’s responsible for the circulation of refrigerant throughout the cooling system.
The compressor is an integral piece of a refrigerator. Homeowners should call on a professional company if the compressor is broken.


A condenser is found on the back exterior wall of the appliance and is there to disperse the warmth built-up inside the refrigerator then out to the surrounding air.


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

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

Expansion Device

Liquified coolant is transferred within a capillary tube which works as an expansion device to cool the gas, thereby turning the gas back into a liquid.


The refrigerator thermostat exists to regulate the current temperature within a refrigerator, starting a new cooling period as necessary.

A thermostat inside of a refrigerator is often prone to issues. Troubleshoot and call a contractor in Massachusetts for service right when a problem occurs.

How Does Refrigeration Work?

1. When the temperature inside the refrigerator goes higher than the set point sensors notify the refrigerator compressor to engage, and then the next cool down begins. The appliance draws in the cool liquified refrigerant, then pressurizes and condenses the liquid, and increases the temperature, in order to turn it into a gas.

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

3. The cooled liquified gas continues its journey towards the evaporator, pushing through the coils in the interior of the appliance and top freezer compartment.

4. The liquid absorbs the warm air from inside the refrigerator, returning the temperature down to the best final point.

5. The refrigerant then will evaporate, and will turn back into a gas form, and then returns to the refrigerator compressor unit to then continue the cycle.

Refrigeration is often used in a number of applications and household appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By removing heat from one place and relocating it to elsewhere the continuous cycle of refrigeration will help cooling your house, provides a perfect environment for perishable food, and also helps with the manufacturing and storage of several different common products and goods.
