Parts of a Refrigerator

There aren’t many houses that do not feature a refrigerator inside the kitchen. It’s been a must-own kitchen appliance for a lot of years now. A refrigerator stores food and drinks at the right temperature, to prevent spoilage and slow down harmful bacteria. The concept of refrigeration works by moving the warmth from the inside of the appliance to the exterior, using principles of evaporation and condensation.

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


The compressor is a combo of a pump and motor, and it is need for circulation of refrigerant dispersed in the cooling system.
A compressor is an important piece of a refrigerator. Homeowners should call a professional service if the compressor is broken.


A condenser is found on the rear exterior panel of the refrigerator and is there to release the heat built-up inside the refrigerator then out to the surrounding air.


The evaporator is stored in the inside of the refrigerator where it absorbs the heat held inside of it, thereby reducing the interior temperature.

Once the evaporator stops working, it is time to hire a professional. Don’t wait too long.

Expansion Device

Liquified refrigerant is directed through a capillary tube that serves as an expansion device as it cools the gas inside, turning it into liquid.


The thermostat helps regulate the current temperature throughout a refrigerator, beginning the cooling cycle as it is necessary.

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

How Does Refrigeration Work?

1. Right when the temperature in the interior of the refrigerator is higher than the set point sensors alert the compressor to engage, and the next cooling period starts. The appliance collects the cool liquid refrigerant, then pressurizes and condenses the refrigerant, and increases the temperature, in order to turn it into a gas form.

2. The refrigerator compressor guides the warm gas in the direction of the refrigerator condenser coils on the exterior of the refrigerator, where it comes into contact with warmer air temperature in the home and returns back to a liquified state.

3. The cool liquid then continues its journey towards the refrigerator evaporator, pushing through the many coils in the interior of the appliance and freezer section.

4. The refrigerant absorbs the hot air from inside the appliance, thereby returning the temperature down to the correct final point.

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

Refrigeration technology is often found in a lot of applications and large appliances, including heat pumps, AC units, refrigerators and residential freezers. By extracting warmth from a single area and relocating it to elsewhere the cycle of refrigeration contributes in cooling a house, provides a optimal storage space for food that is perishable, and helps with manufacturing and storage of a lot of different products and goods.
