Parts of a Refrigerator

You won’t find many houses that do not feature a refrigerator inside the kitchen. It has been a must-have household appliance for many years now. A residential refrigerator can store food at the best temperature, to eliminate rotting and slow down bacteria. The process of refrigeration works by distributing the warmth from the inside of the appliance to the outside, relying on the principles of evaporation and condensation.

The components of your refrigerator are below. For questions or service call Martin Appliance Repair:


The compressor is both a pump and a motor, and it is need for circulation of refrigerant throughout the cooling system.
The compressor is a very important part of a refrigerator. Homeowners should call a professional service if the compressor is broken.


A refrigerator condenser is found on the back outside wall of the refrigerator and helps to emit the warmth collected from inside the refrigerator out into the air.


A evaporator is installed in the inside of the refrigerator where absorbs warmth held inside of it, thereby lowering the temperature inside the appliance.

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

Expansion Device

Liquid refrigerant is carried through a capillary tube that works as an expansion device to cool the gas inside, turning it back into liquid.


A thermostat regulates the temperature throughout the refrigerator, beginning the cooling cycle when it is required.

A thermostat in a refrigerator is prone to breaking. Troubleshoot and hire a repairman in Spokane for repair right when an issue happens.

How Does Refrigeration Work?

1. Once the temperature inside a refrigerator rises above the set point sensors notify the compressor to start, and the cooling cycle begins. The appliance draws in the cold liquified refrigerant, condenses and pressurizes it, and raises the temperature, in order to turn it into a gas form.

2. The refrigerator compressor unit pushes the warm gas in the direction of the condenser coils located on the outside of the refrigerator, at which point it comes into contact with warmer air temperature in the kitchen and returns back to a liquified form.

3. The cool refrigerant then continues on its trip to the refrigerator evaporator component, finding its way through the many coils within the appliance and freezer compartment.

4. The liquid then absorbs the warm air from the interior of the refrigerator, thereby returning the temperature back to the optimal final point.

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

Refrigeration is found in many applications and household appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By extracting warmth from one area and moving it to somewhere else the cycle of refrigeration aids in cooling a home, creates a perfect environment for food that is perishable, and helps with the manufacturing and storage of many different products and materials.
