Parts of a Refrigerator

You won’t find too many houses that do not feature a refrigerator inside the kitchen. It’s been a must-own household appliance for a lot of years now. A household refrigerator will store your food at the optimal temperature, to prevent rotting and limit harmful bacteria. The cycle of refrigeration starts by distributing the warmth from the interior of the appliance to the outside, by using the principles of condensation and evaporation.

The standard components of your refrigerator are. For questions or service call Payne Appliance Repair:


The refrigerator compressor is a combination of a pump and motor, and it is necessary for the circulation of refrigerant dispersed in the system.

The compressor is an integral part of a refrigerator. You should hire a professional company if the compressor is no longer working.


A refrigerator condenser is found on the back exterior wall of the appliance and helps to disperse the warmth collected from within the refrigerator then out into the surrounding air.


A refrigerator evaporator is attached in the inside of the refrigerator where absorbs heat held inside of it, thereby reducing the interior temperature.

The moment an evaporator is not working, it’s time to hire a professional. Do not wait too long.

Expansion Device

Liquid coolant is transported through a capillary tube that works as an expansion tool to cool the gas inside, thereby turning it into liquid.


The refrigerator thermostat exists to regulate the current temperature throughout the refrigerator, starting the cooling period when required.

The thermostat in a refrigerator is often prone to problems. Troubleshoot and call a technician in Michigan for service right after a problem occurs.

How Does Refrigeration Work?

1. Right when the temperature within a refrigerator is higher than the set point sensors signal the refrigerator compressor to begin, and then the next cool down starts. The refrigerator collects the cold liquified refrigerant, pressurizes and condenses it, and increases the temperature, in order to turn it into a gas form.

2. The refrigerator compressor pushes the hot gas towards the refrigerator condenser coils on the back of the unit, at which point it comes into contact with warmer air temperature in the home and returns back to a liquid form.

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

4. The liquid absorbs the hot air from within the appliance, reducing the temperature until it has reached the correct final point.

5. The coolant evaporates, and will return back to a gas, and returns to the compressor unit to continue the cooling cycle.

Refrigeration is used in quite a few applications and household appliances, including heat pumps, AC units, refrigerators and freezers. By contracting warmth from a single place and moving it to elsewhere the continuous cycle of refrigeration aids in cooling your home, provides a perfect environment for perishable food, and also helps with the manufacturing and storage of many different everyday products and materials.
