Parts of a Refrigerator

There are not many homes that do not have a refrigerator in the kitchen. It’s been a must-have household appliance for many years. A refrigerator stores your food and drinks at the optimal temperature, in order to eliminate spoilage and stop the growth of bacteria. The cycle of refrigeration works by transferring the heat from the interior of the unit to the outside, relying on principles of condensation and evaporation.

The parts of a refrigerator are. For questions or service call Ideal Boston Appliance Repair:


The compressor is a combination of a pump and motor, and it is responsible for circulation of refrigerant dispersed in the system.
The compressor is an integral piece of a refrigerator. Homeowners should call on a professional service if the compressor is broken.


A condenser is located on the rear outside panel of the refrigerator and is there to disperse the warmth built-up from inside the refrigerator out to the air.


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

The moment an evaporator isn’t working, it is time to enlist a professional. Do not wait too long.

Expansion Device

Liquified refrigerant is transported within a capillary tube that works as an expansion device as it cools the gas inside, turning the gas back into liquid.


The thermostat will regulate the current temperature within the refrigerator, engaging a new cooling cycle as required.

A thermostat in a refrigerator is prone to issues. Troubleshoot and call a technician in Boston for repair the moment an issue occurs.

How Does Refrigeration Work?

1. Once the temperature inside a refrigerator rises above the set point sensors notify the refrigerator compressor to begin, and then the cooling cycle begins. The appliance attracts the cold liquid refrigerant, then condenses and pressurizes it, and increases the temperature, turning it into a gas.

2. The refrigerator compressor guides the hot gas in the direction of the refrigerator condenser coils on the rear of the refrigerator, at which point it comes into contact with warmer air temperature in the room and returns to a liquid state.

3. The cool refrigerant then continues on its journey towards the evaporator component, pushing through the many coils within the appliance and top freezer.

4. The coolant then absorbs the hot air from within the appliance, thereby cooling the temperature until it has reached the best final point.

5. The liquid will evaporate, and turns back to a gas form, and returns to the compressor in order to then continue the cooling cycle.

Refrigeration technology is often found in many applications and household appliances, including heat pumps, air conditioners, refrigerators and freezers. By removing warmth from a single location and relocating it to a different one the continuous cycle of refrigeration helps cooling your home, creates a optimal storage space for perishable food, and also helps with manufacturing and storage of a number of different products and goods.
