Parts of a Refrigerator

You will not find too many homes that don’t feature a refrigerator inside the kitchen. It has been a must-have household appliance for many years. A household refrigerator stores your food and drinks at the best temperature, to prevent rotting and stop the growth of harmful bacteria. The cycle of refrigeration works by moving the warmth from the interior of the appliance to the outside, by using the principles of condensation and evaporation.

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


The compressor is both a pump and motor, and it is necessary for circulation of refrigerant dispersed in the system.
The compressor is a very important piece of a refrigerator. You should hire a professional company if the compressor is not working.


A refrigerator condenser is located on the back exterior panel of the refrigerator and is there to disperse the heat built-up within the refrigerator out to the surrounding air.


A evaporator is installed in the inside of the refrigerator where it absorbs warmth trapped within it, effectively lowering the temperature inside the unit.

Right when the evaporator stops working, it is time to enlist a professional. You should not wait until it’s too late.

Expansion Device

Liquified coolant is transported through a capillary tube which serves as an expansion device as it cools the gas, thereby turning the gas into liquid.


A refrigerator thermostat regulates the temperature throughout the refrigerator, starting the cooling period when it is required.

A thermostat inside of a refrigerator is often prone to issues. Troubleshoot and hire a repairman in San Bernardino for service right after a problem happens.

How Does Refrigeration Work?

1. Once the temperature within a refrigerator rises above the set point sensors alert the compressor to start, and the cooling period begins. The appliance attracts the cool liquid refrigerant, condenses and pressurizes it, and raises the temperature, in order to turn it into a gas.

2. The compressor guides the hot gas in the direction of the refrigerator condenser coils on the outside of the refrigerator, at which point it comes in contact with the lower air temperature in the home and transforms to a liquified state.

3. The cooled liquified gas continues its journey to the evaporator, pushing through the many coils in the inside of the appliance and freezer.

4. The refrigerant absorbs the warm air from inside the refrigerator, returning the temperature down to the optimal set point.

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

Refrigeration technology is often used in a number of applications and large appliances, this includes heat pumps, air conditioners, refrigerators and residential freezers. By removing heat from one location and then moving it to somewhere else the cycle of refrigeration will help cooling your home, creates a optimal environment for perishable food, and helps with manufacturing and storage of many different common products and goods.
