Parts of a Refrigerator

There are not too many homes that don’t feature a refrigerator in the kitchen. It has been a must-have household appliance for many years now. A residential refrigerator stores food and drinks at the optimal temperature, to eliminate spoilage and limit the growth of bacteria. The concept of refrigeration works by moving the heat from the inside of the refrigerator to the outside, using principles of condensation and evaporation.

The components of a refrigerator are below. For questions or service call Legacy League City Appliance Repair:


The compressor is a combination of a motor and a pump, and it’s need for circulation of refrigerant throughout the cooling system.
The compressor is an important part of a refrigerator. You should call a professional service if the compressor is not working.


The refrigerator condenser is found on the rear outside wall of the appliance and will help to release the warmth absorbed from inside the refrigerator out to the surrounding air.


The evaporator is housed on the inside of the refrigerator where absorbs the warmth held inside of it, effectively reducing the interior temperature.

Once the evaporator stops working, it is time to find a professional. You should not wait until it is too late.

Expansion Device

Liquified coolant is directed through a capillary tube that acts as an expansion device to cool the gas inside, transforming the gas into a liquid.


A refrigerator thermostat exists to regulate the current temperature within a refrigerator, engaging the cooling cycle as it is required.

The thermostat inside of a refrigerator is prone to malfunction. Troubleshoot and hire a technician in League City for service right after an issue occurs.

How Does Refrigeration Work?

1. Right when the temperature within a refrigerator is above the set point sensors alert the compressor to begin, and the next cool down starts. The appliance collects the cold liquid refrigerant, then pressurizes and condenses the liquid, and raises the temperature, so it can turn into a gas form.

2. The refrigerator compressor unit guides the heated gas in the direction of the refrigerator condenser coils on the outside of the appliance, where it comes into contact with warmer temperature in the kitchen and returns to a liquid form.

3. The cool refrigerant continues its trip towards the refrigerator evaporator component, making its way through the many coils within the refrigerator and freezer.

4. The coolant absorbs the heated air from inside the appliance, reducing the temperature back to the optimal final point.

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

Refrigeration is used in quite a few applications and appliances, including heat pumps, AC units, refrigerators and freezers. By contracting warmth from one area and then distributing it to somewhere else the cycle of refrigeration aids in cooling a house, provides a optimal space for food that is perishable, and also helps with manufacturing and storage of a number of different common products and materials.
