Read below to find out all you should understand concerning how a refrigerator runs, how it cools your food and drinks and if it is time to connect with refrigerator repair.

Parts of a Refrigerator

You will not find many homes that don’t have a refrigerator inside the kitchen. It has been a must-own household appliance for several years now. A household refrigerator will store your food at the right temperature, in order to reduce spoilage and stop bacteria. The cycle of refrigeration works by transferring the heat from inside of the unit to the exterior, using principles of condensation and evaporation.

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


The refrigerator compressor is a combo of a pump and motor, and it is responsible for circulation of refrigerant dispensed in the cooling system.

A compressor is an integral piece of a refrigerator. Homeowners should enlist a professional service if the compressor is broken.


A refrigerator condenser is attached on the back exterior wall of the appliance and will help to release the warmth built-up from inside the refrigerator then out in the surrounding air.


A evaporator is installed in the interior of the refrigerator where it absorbs heat trapped within it, thereby reducing the temperature inside the appliance.

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

Expansion Device

Liquified refrigerant is directed through a capillary tube which works as an expansion tool to cool the gas inside, thereby turning the gas into liquid.


A refrigerator thermostat regulates the temperature within the refrigerator, starting the cooling cycle as it is required.

The thermostat inside of a refrigerator is very prone to breaking. Troubleshoot and call a contractor for service right when a problem happens.

How Does Refrigeration Work?

1. Right when the temperature inside the refrigerator rises higher than the set point sensors alert the compressor to engage, and the cool down starts. The appliance collects the cold liquified refrigerant, then pressurizes and condenses it, and raises the temperature, turning it into a gas.

2. The refrigerator compressor directs the heated gas in the direction of the refrigerator condenser coils on the outside of the appliance, where it comes into contact with warmer temperature in the room and returns to a liquified state.

3. The cool refrigerant then continues on its journey to the evaporator component, traveling through the coils on the interior of the refrigerator and top freezer.

4. The refrigerant then absorbs the heated air from the interior of the appliance, thereby lowering the temperature until it has reached the best final point.

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

Refrigeration technology is used in quite a few applications and appliances, including heat pumps, AC units, refrigerators and residential freezers. By extracting heat from one area and moving it to somewhere else the continuous cycle of refrigeration helps cooling your house, creates a perfect space for food that is perishable, and also helps with manufacturing and storage of many different common products and goods.
