Parts of a Refrigerator

You won’t find many houses that do not feature a refrigerator in the kitchen. It has been a must-own kitchen appliance for several years now. A residential refrigerator stores food at the right temperature, to stop spoiling and stop bacteria. The process of refrigeration works by distributing the heat from the inside of the appliance to the outside, by using principles of condensation and evaporation.

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


The refrigerator compressor is both a motor and pump, and it’s need for the circulation of refrigerant dispensed in the cooling system.
The compressor is an integral piece of a refrigerator. You should enlist a professional company if the compressor is broken.


The condenser is attached on the back outside panel of the appliance and is there to disperse the warmth absorbed inside the refrigerator then out into the air.


A refrigerator evaporator is stored in the interior of the refrigerator where absorbs the warmth trapped inside of it, effectively lowering the interior temperature.

The moment an evaporator stops working, it’s time to enlist a professional. Do not wait until it’s too late.

Expansion Device

Liquid coolant is transported within a capillary tube that serves as an expansion device as it cools the gas, transforming the gas back into a liquid.


A thermostat helps regulate the current temperature throughout the refrigerator, beginning a new cooling cycle when required.

A thermostat inside of a refrigerator is often prone to problems. Troubleshoot and call a contractor in Texas for repair right when a problem happens.

How Does Refrigeration Work?

1. When the temperature in the interior of the refrigerator goes higher than the set point sensors signal the refrigerator compressor to begin, and then the cooling period begins. The unit draws in the cool liquid refrigerant, then pressurizes and condenses it, and raises the temperature, in order to turn it into a gas.

2. The refrigerator compressor guides the hot gas towards the refrigerator condenser coils on the outside of the appliance, at which point it comes in contact with warmer temperature in the kitchen and transforms to a liquified state.

3. The cooled refrigerant continues its trip to the evaporator, pushing through the coils in the inside of the refrigerator and top freezer section.

4. The coolant absorbs the heated air from the interior of the refrigerator, thereby cooling the temperature back to the desired set point.

5. The liquid evaporates, and turns back to a gas form, and then returns to the refrigerator compressor unit to then continue the cycle.

Refrigeration technology is often found in quite a few applications and appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By contracting warmth from one place and moving it to another the cycle of refrigeration helps cooling your home, creates a safe storage space for food that is perishable, and also helps with manufacturing and storage of several different common products and materials.
