Parts of a Refrigerator

You won’t find many homes that do not have a refrigerator inside the kitchen. It’s been a must-have appliance for many years now. A residential refrigerator stores your food at the best temperature, to stop spoilage and stop harmful bacteria. The cycle of refrigeration works by distributing the heat from the inside of the unit to the exterior, using the principles of evaporation and condensation.

The main components of a refrigerator are below. For questions or service call Ready Reno Appliance Repair:


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


A refrigerator condenser is found on the rear outside panel of the appliance and is there to emit the warmth collected within the refrigerator out into the air.


A evaporator is housed in the inside of the refrigerator where it absorbs the warmth trapped within it, thereby lowering the interior temperature.

Once an evaporator is not working, it’s time to hire a professional. Don’t wait until it is too late.

Expansion Device

Liquified refrigerant is carried within a capillary tube that acts as an expansion device to cool the gas, transforming the gas back into liquid.


A refrigerator thermostat regulates the current temperature in the interior of a refrigerator, engaging a new cooling period when it is appropriate.

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

How Does Refrigeration Work?

1. Right when the temperature inside the refrigerator rises higher than the set point sensors notify the compressor to begin, and the next cool down starts. The refrigerator draws in the cold liquid refrigerant, condenses and pressurizes the refrigerant, and raises the temperature, so it can turn into a gas form.

2. The refrigerator compressor unit guides the hot gas in the direction of the condenser coils located on the back of the appliance, where it comes in contact with warmer temperature in the home and transforms to a liquified form.

3. The cooled liquified gas continues on its journey towards the evaporator, traveling through the many coils within the appliance and top freezer.

4. The refrigerant absorbs the hot air from within the appliance, thereby reducing the temperature back to the desired final point.

5. The liquid then evaporates, and turns back to a gas state, and then returns to the refrigerator compressor unit so it can then continue the cooling cycle.

Refrigeration is often found in a lot of applications and large appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By extracting heat from one area and then transferring it to another the cycle of refrigeration helps cooling a home, provides a safe environment for food that is perishable, and also helps with manufacturing and storage of several different everyday products and materials.
