Parts of a Refrigerator

You won’t find many houses that don’t feature a refrigerator in the kitchen. It’s been a must-have kitchen appliance for a lot of years. A residential refrigerator can store your food and drinks at the right temperature, in order to reduce spoilage and slow down bacteria. The cycle of refrigeration starts by moving the heat from inside of the appliance to the exterior, relying on principles of condensation and evaporation.

The main parts of a refrigerator are. For questions or service call Pace Appliance Repair:


The refrigerator compressor is a combination of a pump and motor, and it’s responsible for circulation of refrigerant in the cooling system.
A compressor is a very important piece of a refrigerator. You should call on a professional company if the compressor isn’t working.


The condenser is attached on the back outside panel of the refrigerator and helps to emit the warmth absorbed from within the refrigerator out in the surrounding air.


The evaporator is installed on the inside of a refrigerator where absorbs heat trapped inside of it, effectively reducing the interior temperature.

Right when the evaporator is not working, it is time to hire a professional. Don’t wait too long.

Expansion Device

Liquid refrigerant is transferred within a capillary tube that serves as an expansion tool to cool the gas, thereby transforming it into a liquid.


A thermostat helps regulate the current temperature within a refrigerator, starting the cooling cycle as required.

The thermostat inside of a refrigerator is often prone to issues. Troubleshoot and hire a contractor in CITY for service right when a problem occurs.

How Does Refrigeration Work?

1. Right when the temperature inside the refrigerator goes higher than the set point sensors notify the refrigerator compressor to start, and the next cooling cycle begins. The appliance draws in the cold liquified refrigerant, then condenses and pressurizes the liquid, and increases the temperature, turning it into a gas.

2. The compressor unit pushes the hot gas towards the refrigerator condenser coils on the rear of the refrigerator, at which point it comes in contact with the lower temperature in the room and transforms to a liquid form.

3. The cool liquified gas continues on its trip towards the refrigerator evaporator, pushing through the many coils in the interior of the refrigerator and freezer compartment.

4. The refrigerant absorbs the warm air from inside the refrigerator, returning the temperature down to the correct set point.

5. The refrigerant then will evaporate, and will turn back to a gas form, and then returns to the compressor unit to continue the cycle.

Refrigeration technology is used in several applications and appliances, including heat pumps, AC units, refrigerators and residential freezers. By contracting heat from one location and transferring it to another the cycle of refrigeration will help cooling your house, provides a optimal environment for perishable food, and helps with the manufacturing and storage of a number of different common products and goods.
