Parts of a Refrigerator

There aren’t many houses that do not feature a refrigerator in the kitchen. It has been a standard household appliance for a lot of years. A refrigerator stores your food and drinks at the best temperature, to prevent spoiling and stop the growth of bacteria. The process of refrigeration starts by moving the warmth from the interior of the appliance to the exterior, by relying on principles of evaporation and condensation.

The primary parts of a refrigerator are. For questions or service call Achieve Dearborn Appliance Repair:


The refrigerator compressor is both a pump and motor, and it is necessary for the circulation of refrigerant throughout the cooling system.
The compressor is a very important piece of a refrigerator. Homeowners should call a professional service if the compressor is broken.


The refrigerator condenser is attached on the rear exterior wall of the appliance and will help to emit the warmth collected from inside the refrigerator out in the air.


The evaporator is located in the interior of the refrigerator where it absorbs the heat contained within it, thereby reducing the temperature inside the appliance.

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

Expansion Device

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


A refrigerator thermostat will regulate the current temperature in the interior of a refrigerator, engaging a new cooling cycle when needed.

The thermostat inside of a refrigerator is very prone to breaking. Troubleshoot and call a contractor in Dearborn for service right after a problem occurs.

How Does Refrigeration Work?

1. When the temperature in the interior of a refrigerator rises above the set point sensors alert the refrigerator compressor to begin, and the next cooling cycle starts. The refrigerator attracts the cool liquified refrigerant, condenses and pressurizes the liquid, and raises the temperature, so it can turn into a gas form.

2. The refrigerator compressor guides the hot gas towards the condenser coils located on the rear of the unit, where it comes in contact with the lower temperature in the room and transforms to a liquid form.

3. The cool refrigerant then continues on its journey to the refrigerator evaporator, pushing through the coils on the interior of the appliance and top freezer.

4. The liquid then absorbs the hot air from the interior of the refrigerator, returning the temperature down to the correct final point.

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

Refrigeration is often found in quite a few applications and household appliances, including heat pumps, air conditioners, refrigerators and freezers. By contracting heat from one area and then moving it to a different one the cycle of refrigeration helps cooling a house, creates a safe storage space for food that is perishable, and also helps with the manufacturing and storage of many different products and materials.
