Parts of a Refrigerator

You will not find many homes that don’t feature a refrigerator in the kitchen. It has been a must-own appliance for a lot of years. A household refrigerator stores food at the best temperature, to stop spoilage and slow down the growth of bacteria. The cycle of refrigeration works by moving the heat from the inside of the refrigerator to the exterior, using principles of condensation and evaporation.

The parts of your refrigerator are. For questions or service call BRAND:


A refrigerator compressor is a combination of a motor and a pump, and it is responsible for circulation of refrigerant dispensed in the cooling system.
A compressor is an important piece of a refrigerator. Homeowners should hire a professional service if the compressor is not working.


The condenser is attached on the rear exterior wall of the appliance and will help to release the heat absorbed from inside the refrigerator then out to the air.


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

Once an evaporator isn’t working, it is time to hire a professional. Do not wait too long.

Expansion Device

Liquid coolant is directed within a capillary tube which serves as an expansion tool to cool the gas inside, thereby turning the gas into liquid.


A refrigerator thermostat helps regulate the temperature in the interior of the refrigerator, engaging the cooling period when necessary.

A thermostat inside of a refrigerator is very prone to problems. Troubleshoot and hire a repairman in Bellevue for service right when a problem happens.

How Does Refrigeration Work?

1. When the temperature within the refrigerator rises higher than the set point sensors notify the refrigerator compressor to engage, and then the cool down starts. The refrigerator attracts the cool liquid refrigerant, then condenses and pressurizes the liquid, and increases the temperature, so it can turn into a gas form.

2. The refrigerator compressor unit pushes the hot gas towards the condenser coils located on the exterior of the appliance, at which point it comes into contact with the lower air temperature in the kitchen and transforms to a liquid state.

3. The cooled liquified gas then continues on its trip towards the evaporator component, traveling through the coils in the inside of the appliance and top freezer.

4. The refrigerant absorbs the warm air from within the appliance, returning the temperature until it has reached the desired set point.

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

Refrigeration is found in many applications and large appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By extracting warmth from a single location and relocating it to somewhere else the cycle of refrigeration contributes in cooling a house, creates a perfect environment for food that is perishable, and helps with manufacturing and storage of several different products and materials.
