Parts of a Refrigerator

You will not find many houses that don’t feature a refrigerator inside the kitchen. It has been a must-own household appliance for a lot of years now. A refrigerator stores your food at the best temperature, in order to stop spoilage and slow down the growth of harmful bacteria. The concept of refrigeration works by distributing the heat from the interior of the unit to the exterior, using the principles of condensation and evaporation.

The components of your refrigerator are below. For questions or service call Onward Appliance Repair:


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


A refrigerator condenser is located on the back outside panel of the appliance and will help to release the warmth collected inside the refrigerator then out into the air.


A refrigerator evaporator is attached on the inside of a refrigerator where it absorbs heat trapped within it, effectively lowering the temperature inside.

The moment an evaporator isn’t working, it’s time to find a professional. Do not wait until it is too late.

Expansion Device

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


The refrigerator thermostat regulates the current temperature within the refrigerator, starting a new cooling cycle when required.

A thermostat in a refrigerator is very prone to breaking. Troubleshoot and hire a technician in Colorado for repair right after an issue occurs.

How Does Refrigeration Work?

1. When the temperature in the interior of the refrigerator is above the set point sensors notify the refrigerator compressor to begin, and then the cooling period begins. The appliance draws in the cool liquid refrigerant, then condenses and pressurizes the liquid, and increases the temperature, turning it into a gas.

2. The refrigerator compressor directs the warm gas in the direction of the condenser coils on the outside of the unit, at which point it comes into contact with warmer air temperature in the kitchen and transforms to a liquid state.

3. The cooled refrigerant continues its journey towards the refrigerator evaporator, pushing through the many coils on the inside of the appliance and top freezer compartment.

4. The coolant then absorbs the hot air from the interior of the appliance, thereby returning the temperature until it has reached the correct set point.

5. The coolant then evaporates, and will turn back to a gas form, and returns to the compressor so it can continue the cycle.

Refrigeration technology is used in several applications and large appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By extracting heat from a single place and then transferring it to somewhere else the cycle of refrigeration will help cooling a house, creates a perfect environment for perishable food, and helps with the manufacturing and storage of a number of different common products and materials.
