Parts of a Refrigerator

You won’t find too many houses that do not feature a refrigerator inside the kitchen. It has been a must-have appliance for many years. A residential refrigerator stores your food at the optimal temperature, in order to prevent spoiling and limit bacteria. The concept of refrigeration works by transferring the heat from inside of the refrigerator to the exterior, by using the principles of condensation and evaporation.

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


The compressor is both a pump and a motor, and it’s need for the circulation of refrigerant in the cooling system.
A compressor is a very important part of a refrigerator. You should call a professional service if the compressor stops working.


A refrigerator condenser is found on the rear exterior panel of the appliance and will help to disperse the heat built-up from within the refrigerator out to the air.


A evaporator is located on the interior of a refrigerator where it absorbs the warmth held inside of it, thereby lowering the interior temperature.

The moment an evaporator stops working, it is time to hire a professional. You should not wait until it’s too late.

Expansion Device

Liquified coolant is transported through a capillary tube that serves as an expansion tool as it cools the gas, transforming the gas back into liquid.


The refrigerator thermostat exists to regulate the current temperature within a refrigerator, starting the cooling cycle when necessary.

The thermostat inside of a refrigerator is very prone to breaking. Troubleshoot and hire a technician in CITY for service right when a problem happens.

How Does Refrigeration Work?

1. When the temperature in the interior of a refrigerator is higher than the set point sensors signal the compressor to start, and then the cool down starts. The refrigerator collects the cold liquified refrigerant, pressurizes and condenses the refrigerant, and raises the temperature, turning it into a gas form.

2. The refrigerator compressor pushes the heated gas in the direction of the condenser coils located on the exterior of the unit, where it comes into contact with the lower air temperature in the room and transforms to a liquified form.

3. The cooled liquified gas continues on its trip to the evaporator component, pushing through the many coils on the interior of the appliance and top freezer compartment.

4. The refrigerant then absorbs the warm air from within the refrigerator, thereby returning the temperature back to the best set point.

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

Refrigeration technology is used in quite a few applications and appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By extracting heat from one area and relocating it to a different one the cycle of refrigeration helps cooling a house, provides a optimal environment for food that is perishable, and also helps with manufacturing and storage of a number of different common products and goods.
