Parts of a Refrigerator

There aren’t many houses that do not feature a refrigerator in the kitchen. It has been a must-have household appliance for several years now. A residential refrigerator will store food and drinks at the best temperature, in order to prevent rotting and stop harmful bacteria. The cycle of refrigeration works by transferring the warmth from the inside of the appliance to the exterior, relying on principles of condensation and evaporation.

The primary parts of your refrigerator are below. For questions or service call Vance Appliance Repair:


The refrigerator compressor is both a pump and motor, and it is need for circulation of refrigerant throughout the cooling system.
The compressor is a very important part of a refrigerator. You should call on a professional service if the compressor is broken.


A refrigerator condenser is located on the rear exterior wall of the refrigerator and helps to disperse the warmth absorbed within the refrigerator out to the air.


A refrigerator evaporator is located on the interior of the refrigerator where it absorbs warmth held within it, effectively reducing the temperature inside.

Right when an evaporator isn’t working, it is time to enlist a professional. Don’t wait until it is too late.

Expansion Device

Liquid refrigerant is transported within a capillary tube that acts as an expansion tool as it cools the gas, transforming the gas into a liquid.


The refrigerator thermostat regulates the temperature inside the refrigerator, beginning the cooling cycle when needed.

The thermostat in a refrigerator is very prone to malfunction. Troubleshoot and call a technician in Texas for repair right after an issue occurs.

How Does Refrigeration Work?

1. Right when the temperature in the interior of the refrigerator rises higher than the set point sensors signal the compressor to engage, and the cool down begins. The refrigerator collects the cold liquid refrigerant, then condenses and pressurizes the refrigerant, and increases the temperature, so it can turn into a gas.

2. The compressor unit directs the hot gas towards the condenser coils on the back of the unit, at which point it comes in contact with warmer temperature in the kitchen and transforms to a liquid form.

3. The cool refrigerant continues its trip towards the evaporator component, pushing through the many coils in the interior of the refrigerator and top freezer section.

4. The coolant then absorbs the heated air from the interior of the appliance, returning the temperature back 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 to then continue the cycle.

Refrigeration is often used in a number of applications and appliances, including heat pumps, AC units, refrigerators and residential freezers. By extracting heat from a single place and then distributing it to elsewhere the continuous cycle of refrigeration helps cooling your house, creates a safe environment for perishable food, and also helps with the manufacturing and storage of a lot of different common products and goods.
