Parts of a Refrigerator

You will not find many houses that don’t have a refrigerator inside the kitchen. It has been a must-have kitchen appliance for several years. A refrigerator stores your food at the optimal temperature, in order to eliminate spoiling and stop harmful bacteria. The process of refrigeration starts by transferring the heat from inside of the refrigerator to the outside, by using the principles of evaporation and condensation.

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


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


The refrigerator condenser is found on the back exterior panel of the appliance and is there to emit the heat absorbed from within the refrigerator then out in the air.


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

Once an evaporator is not working, it is time to hire a professional. You should not wait too long.

Expansion Device

Liquified refrigerant is transported within a capillary tube that works as an expansion device to cool the gas inside, turning it into a liquid.


A thermostat helps regulate the current temperature throughout the refrigerator, beginning the cooling cycle as necessary.

The thermostat in a refrigerator is very prone to problems. Troubleshoot and hire a technician in Fishers for service right after an issue occurs.

How Does Refrigeration Work?

1. The moment the temperature inside the refrigerator is higher than the set point sensors notify the compressor to engage, and the next cool down starts. The appliance collects the cool liquid refrigerant, condenses and pressurizes the refrigerant, and raises the temperature, turning it into a gas.

2. The compressor pushes the hot gas in the direction of the refrigerator condenser coils located on the rear of the unit, where it comes in contact with warmer air temperature in the kitchen and returns to a liquified form.

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

4. The liquid then absorbs the heated air from within the appliance, cooling the temperature down to the best set point.

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

Refrigeration is often used in many applications and large appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By extracting warmth from one area and then distributing it to another the continuous cycle of refrigeration contributes in cooling a house, creates a perfect space for perishable food, and helps with manufacturing and storage of many different products and goods.
