Parts of a Refrigerator

There are not too many houses that do not feature a refrigerator inside the kitchen. It’s been a must-own appliance for several years now. A refrigerator stores your food and drinks at the best temperature, in order to reduce rotting and limit harmful bacteria. The cycle of refrigeration works by moving the heat from inside of the refrigerator to the outside, relying on principles of condensation and evaporation.

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


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


A condenser is located on the rear exterior wall of the appliance and will help to disperse the warmth collected from inside the refrigerator out to the air.


A evaporator is located on the inside of a refrigerator where absorbs the warmth contained inside of it, thereby reducing the interior temperature.

Once an evaporator stops working, it’s time to find a professional. You should not wait until it’s too late.

Expansion Device

Liquified coolant is transferred within a capillary tube that works as an expansion device as it cools the gas, thereby transforming the gas back into liquid.


The thermostat helps regulate the temperature throughout the refrigerator, engaging the cooling cycle as needed.

A thermostat in a refrigerator is prone to breaking. Troubleshoot and call a contractor in Minnesota for repair right when a problem happens.

How Does Refrigeration Work?

1. The moment the temperature within a refrigerator is above the set point sensors notify the compressor to engage, and then the next cool down begins. The appliance attracts the cold liquified refrigerant, then pressurizes and condenses it, and increases the temperature, turning it into a gas form.

2. The compressor unit directs the warm gas in the direction of the condenser coils located on the exterior of the refrigerator, where it comes into contact with the lower air temperature in the room and returns back to a liquified form.

3. The cool liquid continues on its trip towards the evaporator, making its way through the coils on the interior of the appliance and freezer compartment.

4. The coolant then absorbs the warm air from within the refrigerator, thereby returning the temperature until it has reached the correct final point.

5. The coolant will evaporate, and turns back into a gas state, and returns to the refrigerator compressor in order to continue the cycle.

Refrigeration technology is found in many applications and household appliances, this includes heat pumps, AC units, refrigerators and freezers. By contracting heat from one location and then relocating it to elsewhere the cycle of refrigeration aids in cooling your house, creates a perfect storage space for perishable food, and helps with the manufacturing and storage of several different everyday products and materials.
