Parts of a Refrigerator

There aren’t too many houses that do not feature a refrigerator in the kitchen. It’s been a standard kitchen appliance for a lot of years now. A residential refrigerator will store your food at the right temperature, to reduce spoilage and limit bacteria. The cycle of refrigeration works by transferring the warmth from inside of the unit to the outside, by relying on the principles of evaporation and condensation.

The main parts of your refrigerator are. For questions or service call Smithtown Appliance Repair:


The refrigerator compressor is both a motor and pump, and it is necessary for the circulation of refrigerant in the system.
The compressor is an important piece of a refrigerator. Homeowners should enlist a professional service if the compressor is broken.


A refrigerator condenser is attached on the rear exterior wall of the appliance and is there to release the warmth absorbed from within the refrigerator then out in the air.


A evaporator is stored on the interior of a refrigerator where absorbs the heat trapped inside of it, effectively reducing the temperature inside the unit.

The moment an evaporator isn’t working, it is time to find a professional. Don’t wait until it’s too late.

Expansion Device

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


A refrigerator thermostat helps regulate the current temperature inside the refrigerator, engaging the cooling period as necessary.

A thermostat in a refrigerator is often prone to problems. Troubleshoot and call a repairman in Smithtown 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 notify the compressor to start, and then the cooling cycle starts. The unit draws in the cold liquid refrigerant, pressurizes and condenses the liquid, and increases the temperature, in order to turn it into a gas form.

2. The refrigerator compressor unit directs the warm gas towards the refrigerator condenser coils on the outside of the appliance, at which point it comes into contact with the lower temperature in the kitchen and returns to a liquified form.

3. The cool liquid then continues its trip towards the evaporator component, pushing through the many coils on the interior of the refrigerator and top freezer compartment.

4. The coolant then absorbs the warm air from the interior of the appliance, returning the temperature down to the desired final point.

5. The liquid evaporates, and will return back to a gas form, and returns to the compressor so it can continue the cooling cycle.

Refrigeration technology is used in a lot of applications and appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By removing heat from one area and moving it to somewhere else the continuous cycle of refrigeration contributes in cooling your home, provides a optimal storage space for perishable food, and helps with the manufacturing and storage of a number of different everyday products and goods.
