Parts of a Refrigerator

There are not many houses that do not have a refrigerator in the kitchen. It has been a standard household appliance for a lot of years now. A refrigerator stores your food and drinks at the right temperature, in order to reduce spoilage and slow down bacteria. The cycle of refrigeration starts by distributing the warmth from the inside of the appliance to the outside, relying on the principles of condensation and evaporation.

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


A compressor is a combo of a motor and a pump, and it is need for the circulation of refrigerant dispensed in the cooling system.
A compressor is an important part of a refrigerator. You should call on a professional service if the compressor isn’t working.


The refrigerator condenser is located on the rear outside panel of the refrigerator and helps to emit the heat collected inside the refrigerator then out to the surrounding air.


The evaporator is stored in the inside of a refrigerator where absorbs warmth contained within it, effectively reducing the temperature inside the refrigerator.

The moment the evaporator isn’t working, it is time to enlist a professional. Don’t wait too long.

Expansion Device

Liquified refrigerant is transported through a capillary tube which acts as an expansion tool to cool the gas, transforming it into a liquid.


A refrigerator thermostat regulates the current temperature in the interior of a refrigerator, starting the cooling cycle when it is appropriate.

A thermostat inside of a refrigerator is often prone to problems. Troubleshoot and hire a contractor in CITY for service right after an issue happens.

How Does Refrigeration Work?

1. When the temperature within a refrigerator is above the set point sensors signal the refrigerator compressor to begin, and then the cooling period begins. The refrigerator attracts the cool liquid refrigerant, then pressurizes and condenses the liquid, and raises the temperature, turning it into a gas form.

2. The compressor unit guides the hot gas in the direction of the refrigerator condenser coils on the rear of the refrigerator, at which point it comes in contact with the lower air temperature in the kitchen and transforms back to a liquid form.

3. The cooled liquid then continues on its trip to the refrigerator evaporator, making its way through the coils in the interior of the refrigerator and top freezer section.

4. The coolant absorbs the warm air from inside the refrigerator, reducing the temperature until it has reached the correct final point.

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

Refrigeration technology is used in a lot of applications and appliances, including heat pumps, AC units, refrigerators and residential freezers. By contracting warmth from one location and then distributing it to a different one the cycle of refrigeration aids in cooling a home, creates a safe storage space for food that is perishable, and also helps with the manufacturing and storage of several different products and goods.
