Parts of a Refrigerator

There aren’t many houses that don’t feature a refrigerator in the kitchen. It’s been a standard kitchen appliance for several years now. A household refrigerator will store food and drinks at the optimal temperature, in order to eliminate spoilage and limit the growth of harmful bacteria. The concept of refrigeration works by distributing the warmth from the interior of the appliance to the outside, using the principles of evaporation and condensation.

The standard parts of your refrigerator are. For questions or service call Webb Appliance Repair:


A compressor is a combination of a motor and a pump, and it is necessary for the circulation of refrigerant in the system.
A compressor is a very important part of a refrigerator. You should call on a professional company if the compressor is broken.


The condenser is located on the back outside panel of the appliance and helps to disperse the warmth collected from inside the refrigerator then out into the surrounding air.


A evaporator is housed in the inside of a refrigerator where it absorbs warmth trapped inside of it, effectively lowering the temperature inside the refrigerator.

The moment the evaporator isn’t working, it’s time to call a professional. You should not wait too long.

Expansion Device

Liquid refrigerant is carried within a capillary tube which acts as an expansion device to cool the gas, thereby transforming the gas back into liquid.


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

A thermostat inside of a refrigerator is very prone to breaking. Troubleshoot and call a repairman in Mesa for service the moment a problem happens.

How Does Refrigeration Work?

1. When the temperature inside a refrigerator rises above the set point sensors alert the compressor to begin, and then the next cooling cycle begins. The refrigerator draws in the cool liquid refrigerant, condenses and pressurizes it, and raises the temperature, in order to turn it into a gas form.

2. The compressor unit guides the heated gas towards the refrigerator condenser coils located on the exterior of the appliance, where it comes in contact with warmer air temperature in the home and returns back to a liquified state.

3. The cool liquid then continues on its journey towards the evaporator component, traveling through the coils within the refrigerator and freezer.

4. The liquid absorbs the warm air from the interior of the refrigerator, thereby reducing the temperature until it has reached the desired set point.

5. The refrigerant then evaporates, and will return back into a gas, and returns to the compressor unit in order to then continue the cooling cycle.

Refrigeration technology is used in many applications and large appliances, including heat pumps, AC units, refrigerators and residential freezers. By contracting warmth from a single place and then moving it to another the cycle of refrigeration will help cooling your house, creates a optimal space for food that is perishable, and helps with manufacturing and storage of a number of different products and materials.
