Parts of a Refrigerator

You won’t find too many homes that do not feature a refrigerator in the kitchen. It’s been a must-own household appliance for many years. A household refrigerator stores food at the optimal temperature, to eliminate spoilage and limit bacteria. The cycle of refrigeration starts by distributing the heat from the inside of the appliance to the exterior, using the principles of condensation and evaporation.

The parts of your refrigerator are. For questions or service call Ready Appliance Repair:


The refrigerator compressor is a combo of a motor and pump, and it’s need for the circulation of refrigerant throughout the cooling system.
A compressor is a very important part of a refrigerator. You should hire a professional company if the compressor is not working.


The refrigerator condenser is attached on the back outside panel of the appliance and helps to release the heat collected from within the refrigerator out to the surrounding air.


A refrigerator evaporator is attached on the inside of a refrigerator where absorbs heat held within it, effectively reducing the interior temperature.

The moment the evaporator is not working, it is time to call a professional. You should not wait until it is too late.

Expansion Device

Liquid coolant is directed within a capillary tube that acts as an expansion tool as it cools the gas inside, thereby transforming it into a liquid.


A refrigerator thermostat helps regulate the temperature within the refrigerator, starting the cooling period when necessary.

The thermostat in a refrigerator is prone to problems. Troubleshoot and hire a technician in Annandale for repair the moment an issue occurs.

How Does Refrigeration Work?

1. Once the temperature within the refrigerator goes above the set point sensors signal the compressor to start, and then the cooling cycle begins. The unit attracts the cool liquid refrigerant, condenses and pressurizes the liquid, and increases the temperature, turning it into a gas form.

2. The compressor guides the warm gas in the direction of the condenser coils located on the exterior of the refrigerator, at which point it comes into contact with warmer temperature in the room and reverts back to a liquified state.

3. The cool refrigerant then continues on its trip towards the refrigerator evaporator, traveling through the many coils on the inside of the refrigerator and top freezer section.

4. The refrigerant absorbs the warm air from the interior of the refrigerator, thereby lowering the temperature back to the correct final point.

5. The refrigerant will evaporate, and turns back to a gas state, and returns to the compressor unit so it can continue the cycle.

Refrigeration technology is often found in a number of applications and large appliances, this includes heat pumps, air conditioners, refrigerators and freezers. By contracting heat from a single location and then relocating it to a different one the continuous cycle of refrigeration will help cooling your house, provides a optimal storage space for food that is perishable, and helps with the manufacturing and storage of a number of different everyday products and materials.
