Parts of a Refrigerator

You won’t find too many houses that don’t have a refrigerator in the kitchen. It’s been a must-have kitchen appliance for several years now. A household refrigerator is able to store food and drinks at the best temperature, to reduce spoiling and slow down the growth of bacteria. The process of refrigeration works by distributing the heat from the inside of the unit to the outside, by relying on the principles of evaporation and condensation.

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


A refrigerator compressor is both a pump and motor, and it’s necessary for circulation of refrigerant throughout the system.

The compressor is a very important part of a refrigerator. You should hire a professional service if the compressor is broken.


A refrigerator condenser is located on the rear exterior wall of the refrigerator and helps to release the heat built-up within the refrigerator out in the air.


The refrigerator evaporator is stored on the interior of a refrigerator where absorbs the warmth held inside of it, effectively reducing the temperature inside the appliance.

Once the evaporator isn’t working, it is time to call a professional. You should not wait until it’s too late.

Expansion Device

Liquid refrigerant is directed within a capillary tube which works as an expansion tool as it cools the gas, thereby transforming the gas back into a liquid.


The refrigerator thermostat helps regulate the current temperature inside the refrigerator, starting the cooling cycle when appropriate.

A thermostat inside of a refrigerator is prone to problems. Troubleshoot and call a technician in Appleton for service the moment an issue occurs.

How Does Refrigeration Work?

1. The moment the temperature inside a refrigerator is higher than the set point sensors alert the refrigerator compressor to start, and then the cool down starts. The refrigerator attracts the cold liquified refrigerant, then condenses and pressurizes it, and increases the temperature, turning it into a gas.

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

3. The cooled refrigerant then continues its trip towards the refrigerator evaporator component, traveling through the many coils on the interior of the refrigerator and freezer section.

4. The liquid absorbs the heated air from within the refrigerator, thereby reducing the temperature back to the desired set point.

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

Refrigeration is often found in several applications and appliances, this includes heat pumps, air conditioners, refrigerators and residential freezers. By extracting heat from one place and then moving it to another the cycle of refrigeration aids in cooling your home, provides a perfect storage space for perishable food, and also helps with the manufacturing and storage of several different everyday products and goods.
