Parts of a Refrigerator

There aren’t too many houses that do not feature a refrigerator in the kitchen. It has been a standard kitchen appliance for several years now. A residential refrigerator will store food at the optimal temperature, to stop spoiling and limit the growth of harmful bacteria. The cycle of refrigeration starts by moving the warmth from the interior of the unit to the exterior, relying on principles of evaporation and condensation.

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


A compressor is both a pump and a motor, and it is responsible for circulation of refrigerant throughout the system.
The compressor is a very important piece of a refrigerator. You should hire a professional service if the compressor is broken.


The refrigerator condenser is attached on the back outside wall of the appliance and will help to release the warmth absorbed from inside the refrigerator out to the air.


The evaporator is stored in the inside of the refrigerator where absorbs heat trapped inside of it, thereby lowering the temperature inside the appliance.

The moment an evaporator isn’t working, it is time to enlist a professional. You should not wait until it is too late.

Expansion Device

Liquified refrigerant is transferred through a capillary tube that works as an expansion device to cool the gas, turning the gas back into a liquid.


The refrigerator thermostat helps regulate the current temperature inside a refrigerator, starting the cooling period when it is needed.

A thermostat in a refrigerator is often prone to malfunction. Troubleshoot and hire a contractor in CITY for service right when an issue happens.

How Does Refrigeration Work?

1. The moment the temperature inside the refrigerator goes above the set point sensors alert the compressor to begin, and then the next cool down begins. The unit draws in the cool liquid refrigerant, then pressurizes and condenses the refrigerant, and raises the temperature, so it can turn into a gas form.

2. The refrigerator compressor unit directs the heated gas in the direction of the refrigerator condenser coils on the outside of the appliance, where it comes in contact with warmer air temperature in the room and transforms back to a liquid state.

3. The cool liquid continues on its journey to the refrigerator evaporator component, pushing through the coils within the appliance and freezer section.

4. The coolant then absorbs the heated air from the interior of the refrigerator, reducing the temperature back to the best set point.

5. The liquid will evaporate, and will turn back into a gas state, and returns to the compressor unit in order to then continue the cycle.

Refrigeration is often used in quite a few applications and household appliances, this includes heat pumps, AC units, refrigerators and freezers. By extracting heat from a single area and distributing it to somewhere else the continuous cycle of refrigeration aids in cooling a home, creates a optimal storage space for food that is perishable, and also helps with manufacturing and storage of a lot of different everyday products and goods.
