Parts of a Refrigerator

There aren’t many houses that don’t have a refrigerator inside the kitchen. It has been a standard household appliance for several years now. A refrigerator is able to store your food and drinks at the best temperature, in order to reduce spoiling and slow down the growth of harmful bacteria. The process of refrigeration starts by distributing the warmth from inside of the unit to the exterior, relying on principles of condensation and evaporation.

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


A compressor is both a pump and motor, and it’s need for the circulation of refrigerant dispersed in the cooling system.

A compressor is an integral part of a refrigerator. You should call on a professional company if the compressor isn’t working.


A refrigerator condenser is found on the rear outside wall of the refrigerator and will help to release the heat built-up from within the refrigerator then out into the air.


The evaporator is located on the inside of a refrigerator where absorbs the heat trapped inside of it, effectively lowering the interior temperature.

Once an evaporator isn’t working, it is time to enlist a professional. Do not wait too long.

Expansion Device

Liquified coolant is transported within a capillary tube that acts as an expansion tool to cool the gas inside, thereby turning the gas back into a liquid.


A thermostat helps regulate the current temperature inside a refrigerator, starting the cooling period when required.

A thermostat inside of a refrigerator is often prone to issues. Troubleshoot and call a contractor in Wichita for service right when an issue happens.

How Does Refrigeration Work?

1. When the temperature in the interior of the refrigerator is higher than the set point sensors alert the refrigerator compressor to start, and then the cooling cycle begins. The refrigerator attracts the cool liquified refrigerant, then pressurizes and condenses the refrigerant, and increases the temperature, turning it into a gas form.

2. The compressor guides the hot gas towards the refrigerator condenser coils on the exterior of the unit, where it comes in contact with the lower air temperature in the room and reverts to a liquid state.

3. The cooled refrigerant then continues its trip to the evaporator, making its way through the coils in the inside of the refrigerator and freezer compartment.

4. The liquid absorbs the hot air from within the appliance, thereby returning the temperature back to the optimal set point.

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

Refrigeration technology is found in many applications and household appliances, this includes heat pumps, air conditioners, refrigerators and freezers. By removing heat from a single location and then relocating it to somewhere else the cycle of refrigeration will help cooling a home, provides a optimal environment for perishable food, and also helps with manufacturing and storage of many different everyday products and goods.
