Parts of a Refrigerator

You won’t find many homes that don’t have a refrigerator inside the kitchen. It has been a standard appliance for several years. A household refrigerator can store your food and drinks at the best temperature, in order to prevent spoilage and slow down bacteria. The concept of refrigeration works by transferring the warmth from the inside of the unit to the outside, using the principles of condensation and evaporation.

The main components of a refrigerator are below. For questions or service call Moore Appliance Repair:


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


The refrigerator condenser is found on the rear exterior wall of the appliance and will help to disperse the heat absorbed from inside the refrigerator then out into the air.


A refrigerator evaporator is attached on the inside of the refrigerator where it absorbs warmth held inside of it, effectively lowering the temperature inside the appliance.

Right when the evaporator stops working, it is time to hire a professional. You should not wait too long.

Expansion Device

Liquified refrigerant is transferred through a capillary tube that acts as an expansion tool as it cools the gas, thereby turning it back into liquid.


A thermostat regulates the current temperature throughout a refrigerator, beginning the cooling period as appropriate.

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

How Does Refrigeration Work?

1. Right when the temperature within the refrigerator goes higher than the set point sensors alert the compressor to start, and then the cool down begins. The appliance draws in the cold liquified refrigerant, pressurizes and condenses it, and increases the temperature, in order to turn it into a gas.

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

3. The cool liquified gas then continues its trip to the refrigerator evaporator component, traveling through the coils within the appliance and top freezer section.

4. The coolant absorbs the heated air from inside the appliance, cooling the temperature back to the optimal set point.

5. The coolant then evaporates, and will turn back to a gas, and returns to the compressor unit so it can then continue the cycle.

Refrigeration is found in a number of applications and large appliances, this includes heat pumps, AC units, refrigerators and freezers. By removing warmth from one area and then distributing it to somewhere else the cycle of refrigeration helps cooling a house, provides a safe storage space for perishable food, and helps with manufacturing and storage of a lot of different common products and materials.
