Parts of a Refrigerator

There are not too many homes that don’t have a refrigerator in the kitchen. It’s been a must-have household appliance for many years now. A household refrigerator stores food and drinks at the optimal temperature, to prevent rotting and stop harmful bacteria. The cycle of refrigeration starts by transferring the heat from the interior of the unit to the exterior, using principles of evaporation and condensation.

The primary parts of your refrigerator are below. For questions or service call Garden Grove Appliance Repair:


A compressor is a combo of a pump and motor, and it’s responsible for circulation of refrigerant throughout the cooling system.
The compressor is an important piece of a refrigerator. You should hire a professional company if the compressor is no longer working.


The refrigerator condenser is located on the rear outside wall of the appliance and helps to disperse the warmth collected from inside the refrigerator then out in the air.


A refrigerator evaporator is installed in the inside of a refrigerator where absorbs the warmth trapped inside of it, effectively reducing the temperature inside the appliance.

Once an evaporator is not working, it is time to find a professional. You should not wait until it is too late.

Expansion Device

Liquified coolant is carried within a capillary tube which works as an expansion device to cool the gas inside, thereby turning the gas into a liquid.


A refrigerator thermostat regulates the temperature throughout the refrigerator, engaging a new cooling cycle as it is needed.

The thermostat in a refrigerator is prone to issues. Troubleshoot and hire a contractor in Garden Grove for repair the moment an issue happens.

How Does Refrigeration Work?

1. Right when the temperature within the refrigerator rises above the set point sensors notify the compressor to begin, and then the cooling cycle begins. The appliance attracts the cool liquid refrigerant, pressurizes and condenses the refrigerant, and raises the temperature, turning it into a gas form.

2. The compressor guides the hot gas in the direction of the refrigerator condenser coils located on the back of the appliance, where it comes into contact with warmer air temperature in the room and transforms to a liquified form.

3. The cool liquified gas then continues its trip towards the evaporator, finding its way through the many coils in the interior of the appliance and freezer section.

4. The liquid absorbs the hot air from within the refrigerator, cooling the temperature back to the best set point.

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

Refrigeration technology is found in a number of applications and household appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By extracting warmth from one area and distributing it to somewhere else the continuous cycle of refrigeration will help cooling your house, creates a perfect space for perishable food, and helps with manufacturing and storage of a lot of different products and materials.
