Parts of a Refrigerator

There are not too many homes that do not feature a refrigerator in the kitchen. It has been a must-have household appliance for several years. A household refrigerator stores food at the best temperature, in order to reduce spoilage and stop the growth of harmful bacteria. The concept of refrigeration starts by distributing the heat from the interior of the refrigerator to the exterior, by relying on the principles of evaporation and condensation.

The main parts of a refrigerator are. For questions or service call Dynamic Dayton Appliance Repair:


A refrigerator compressor is a combination of a motor and a pump, and it’s necessary for circulation of refrigerant in the cooling system.
The compressor is a very important part of a refrigerator. Homeowners should enlist a professional service if the compressor is broken.


The refrigerator condenser is located on the back outside wall of the appliance and will help to release the heat built-up from inside the refrigerator then out in the air.


A evaporator is located in the interior of the refrigerator where absorbs heat contained inside of it, effectively reducing the interior temperature.

Right when the evaporator stops working, it is time to hire a professional. Don’t wait too long.

Expansion Device

Liquid coolant is directed through a capillary tube that acts as an expansion tool to cool the gas inside, thereby turning it into liquid.


A thermostat helps regulate the temperature within the refrigerator, engaging a new cooling cycle as it is appropriate.

The thermostat in a refrigerator is often prone to issues. Troubleshoot and hire a technician in Dayton for repair the moment an issue occurs.

How Does Refrigeration Work?

1. Right when the temperature within the refrigerator rises above the set point sensors alert the refrigerator compressor to start, and the cool down starts. The appliance draws in the cold liquid refrigerant, then condenses and pressurizes the liquid, and increases the temperature, in order to turn it into a gas.

2. The refrigerator compressor unit pushes the warm gas in the direction of the condenser coils located on the exterior of the refrigerator, at which point it comes in contact with warmer air temperature in the room and returns to a liquified state.

3. The cooled refrigerant then continues on its trip towards the refrigerator evaporator, traveling through the coils within the refrigerator and freezer.

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

5. The coolant then evaporates, and will turn back into a gas form, and then returns to the compressor in order to then continue the cycle.

Refrigeration technology is often found in many applications and appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By extracting heat from one place and then moving it to somewhere else the cycle of refrigeration aids in cooling your house, creates a safe storage space for perishable food, and helps with the manufacturing and storage of many different common products and materials.
