Parts of a Refrigerator

You will not find many homes that do not have a refrigerator inside the kitchen. It has been a standard appliance for a lot of years now. A household refrigerator stores your food at the right temperature, in order to eliminate spoilage and limit the growth of bacteria. The cycle of refrigeration works by transferring the warmth from the inside of the appliance to the outside, using principles of condensation and evaporation.

The standard components of a refrigerator are. For questions or service call Wells Appliance Repair:


The compressor is both a motor and pump, and it’s responsible for the circulation of refrigerant throughout the cooling system.
The compressor is a very important part of a refrigerator. You should hire a professional service if the compressor is broken.


The condenser is located on the rear outside panel of the appliance and is there to emit the warmth absorbed within the refrigerator then out to the surrounding air.


A evaporator is attached on the inside of the refrigerator where absorbs the warmth contained within it, thereby lowering the temperature inside the unit.

Once the evaporator isn’t working, it is time to find a professional. You should not wait until it is too late.

Expansion Device

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


The thermostat will regulate the temperature within the refrigerator, beginning the cooling cycle when required.

A thermostat inside of a refrigerator is prone to malfunction. Troubleshoot and call a contractor in Fremont for service right when a problem occurs.

How Does Refrigeration Work?

1. When the temperature inside a refrigerator is above the set point sensors alert the compressor to begin, and then the cool down starts. The unit collects the cold liquid refrigerant, condenses and pressurizes the refrigerant, and increases the temperature, in order to turn it into a gas.

2. The refrigerator compressor guides the hot gas towards the refrigerator condenser coils on the back of the unit, where it comes in contact with the lower temperature in the home and transforms back to a liquified state.

3. The cool liquid continues its trip towards the evaporator component, traveling through the many coils on the inside of the refrigerator and freezer compartment.

4. The coolant absorbs the warm air from within the appliance, thereby cooling the temperature back to the optimal set point.

5. The liquid then will evaporate, and will turn back into a gas, and returns to the refrigerator compressor to then continue the cooling cycle.

Refrigeration is often found in a lot of applications and appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By extracting heat from a single location and relocating it to a different one the cycle of refrigeration helps cooling a home, provides a optimal space for perishable food, and helps with manufacturing and storage of a number of different products and materials.
