Parts of a Refrigerator

You won’t find many houses that do not feature a refrigerator in the kitchen. It’s been a must-have kitchen appliance for several years. A household refrigerator stores your food at the right temperature, in order to stop rotting and slow down the growth of harmful bacteria. The cycle of refrigeration works by moving the heat from the interior of the unit to the exterior, using principles of evaporation and condensation.

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


A refrigerator compressor is a combo of a pump and motor, and it’s responsible for the circulation of refrigerant in the system.
A compressor is a very important part of a refrigerator. You should call a professional company if the compressor is broken.


A refrigerator condenser is attached on the rear exterior panel of the appliance and helps to release the warmth built-up from inside the refrigerator then out into the surrounding air.


A evaporator is attached in the interior of the refrigerator where absorbs heat contained within it, effectively lowering the interior temperature.

The moment the evaporator isn’t working, it’s time to call a professional. You should not wait too long.

Expansion Device

Liquid coolant is transported through a capillary tube which works as an expansion device as it cools the gas, thereby turning it back into a liquid.


A refrigerator thermostat exists to regulate the temperature in the interior of the refrigerator, starting the cooling period as it is required.

The thermostat inside of a refrigerator is often prone to problems. Troubleshoot and call a repairman in Providence for repair right after an issue happens.

How Does Refrigeration Work?

1. When the temperature inside a refrigerator is higher than the set point sensors signal the refrigerator compressor to start, and the next cool down starts. The refrigerator draws in the cold liquid refrigerant, condenses and pressurizes the liquid, and increases the temperature, in order to turn it into a gas.

2. The compressor unit directs the hot gas in the direction of the condenser coils located on the exterior of the appliance, at which point it comes into contact with the lower temperature in the room and returns back to a liquid form.

3. The cool refrigerant then continues on its trip towards the refrigerator evaporator, making its way through the coils within the refrigerator and top freezer compartment.

4. The coolant then absorbs the warm air from the interior of the appliance, thereby cooling the temperature until it has reached the correct set point.

5. The liquid then evaporates, and will return back to a gas form, and then returns to the compressor unit to then continue the cycle.

Refrigeration is found in quite a few applications and household appliances, including heat pumps, air conditioners, refrigerators and freezers. By extracting warmth from a single place and moving it to somewhere else the continuous cycle of refrigeration will help cooling your house, provides a perfect environment for perishable food, and helps with manufacturing and storage of a number of different products and materials.
