Parts of a Refrigerator

You won’t find many homes that don’t have a refrigerator inside the kitchen. It has been a must-have kitchen appliance for several years. A household refrigerator stores your food and drinks at the right temperature, in order to reduce spoiling and slow down bacteria. The concept of refrigeration works by distributing the warmth from the interior of the appliance to the exterior, relying on the principles of evaporation and condensation.

The standard parts of a refrigerator are below. For questions or service call Price Appliance Repair:


The refrigerator compressor is a combination of a pump and motor, and it’s need for circulation of refrigerant in the cooling system.
The compressor is a very important piece of a refrigerator. You should hire a professional service if the compressor isn’t working.


A refrigerator condenser is found on the back outside panel of the refrigerator and helps to disperse the warmth absorbed from within the refrigerator then out to the air.


A refrigerator evaporator is located on the interior of the refrigerator where it absorbs heat held inside of it, effectively reducing the temperature inside the refrigerator.

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

Expansion Device

Liquid refrigerant is carried within a capillary tube that works as an expansion tool to cool the gas, thereby transforming the gas back into liquid.


The thermostat regulates the current temperature throughout the refrigerator, beginning the cooling period when it is required.

The thermostat in a refrigerator is often prone to breaking. Troubleshoot and call a contractor in Alabama for service right when a problem occurs.

How Does Refrigeration Work?

1. Right when the temperature in the interior of the refrigerator rises higher than the set point sensors signal the compressor to begin, and the next cooling cycle begins. The appliance draws in the cold liquified refrigerant, then pressurizes and condenses the liquid, and raises the temperature, turning it into a gas.

2. The compressor pushes the hot gas in the direction of the condenser coils on the outside of the appliance, where it comes in contact with the lower air temperature in the home and returns back to a liquid form.

3. The cooled liquid continues on its trip towards the refrigerator evaporator, finding its way through the coils in the inside of the appliance and top freezer section.

4. The coolant absorbs the warm air from within the appliance, lowering the temperature down to the best final point.

5. The coolant will evaporate, and turns back to a gas, and then returns to the compressor to continue the cooling cycle.

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