Parts of a Refrigerator

You will not find too many homes that don’t have a refrigerator in the kitchen. It has been a must-have kitchen appliance for several years now. A household refrigerator stores food at the best temperature, in order to prevent rotting and limit harmful bacteria. The concept of refrigeration starts by moving the warmth from inside of the refrigerator to the outside, by relying on principles of evaporation and condensation.

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


A refrigerator compressor is both a motor and pump, and it is necessary for the circulation of refrigerant in the system.
A compressor is a very important piece of a refrigerator. Homeowners should call for refrigerator repairs if the compressor in the appliance is not working.


The refrigerator condenser is found on the back outside panel of the appliance and helps to disperse the heat absorbed inside the refrigerator out into the surrounding air.


A evaporator is installed in the inside of the refrigerator where it absorbs the heat held within it, effectively lowering the temperature inside the appliance. If the evaporator is not working, it’s time to call a professional. You should not wait too long.

Expansion Device

Liquified coolant is carried through a capillary tube that works as an expansion device to cool the gas, transforming it into a liquid.


A refrigerator thermostat regulates the current temperature in the interior of the refrigerator, starting a new cooling cycle as necessary. The thermostat inside of a refrigerator is prone to issues. Troubleshoot and hire a repairman in Madison for service right when an issue occurs.

How Does Refrigeration Work?

1. Right when the temperature inside a refrigerator goes above the set point sensors signal the compressor to begin, and then the cool down starts. The appliance draws in the cold liquified refrigerant, then pressurizes and condenses the refrigerant, and raises the temperature, so it can turn into a gas form.

2. The compressor pushes the warm gas towards the condenser coils on the outside of the unit, where it comes in contact with warmer air temperature in the kitchen and returns back to a liquified form.

3. The cooled liquid continues on its trip towards the refrigerator evaporator, pushing through the coils within the appliance and top freezer compartment.

4. The refrigerant absorbs the warm air from within the appliance, thereby reducing the temperature down to the best final point.

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

Refrigeration is often used in quite a few applications and appliances, including heat pumps, AC units, refrigerators and freezers. By contracting warmth from one area and moving it to a different one the cycle of refrigeration aids in cooling a house, creates a safe environment for perishable food, and helps with manufacturing and storage of several different everyday products and goods.
