Parts of a Refrigerator

There aren’t too many houses that don’t have a refrigerator inside the kitchen. It has been a must-own household appliance for several years now. A residential refrigerator can store your food at the best temperature, to stop rotting and stop bacteria. The process of refrigeration starts by moving the heat from the interior of the appliance to the exterior, using the principles of condensation and evaporation.

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


The refrigerator compressor is a combination of a pump and motor, and it is need for circulation of refrigerant dispersed in the cooling system.
The compressor is a very important piece of a refrigerator. Homeowners should call on a professional company if the compressor isn’t working.


The condenser is found on the rear outside wall of the appliance and is there to emit the heat absorbed within the refrigerator then out to the surrounding air.


The refrigerator evaporator is housed on the interior of a refrigerator where it absorbs the heat trapped within it, effectively lowering the interior temperature.

The moment the evaporator is not working, it is time to call a professional. Do not wait until it’s too late.

Expansion Device

Liquified refrigerant is transported through a capillary tube which acts as an expansion device as it cools the gas, turning the gas into a liquid.


The refrigerator thermostat regulates the current temperature in the interior of a refrigerator, beginning a new cooling cycle as necessary.

The thermostat in a refrigerator is very prone to issues. Troubleshoot and call a technician in Glendale for repair right after an issue occurs.

How Does Refrigeration Work?

1. When the temperature within a refrigerator rises above the set point sensors alert the refrigerator compressor to begin, and the cooling period starts. The appliance collects the cold liquid refrigerant, then pressurizes and condenses the liquid, and increases the temperature, turning it into a gas form.

2. The compressor unit guides the heated gas in the direction of the refrigerator condenser coils on the exterior of the unit, at which point it comes in contact with warmer air temperature in the room and reverts to a liquid state.

3. The cool liquified gas then continues on its journey towards the evaporator, pushing through the many coils in the inside of the appliance and freezer section.

4. The coolant then absorbs the hot air from inside the refrigerator, thereby reducing the temperature down to the desired final point.

5. The refrigerant then evaporates, and will return back to a gas, and returns to the refrigerator compressor to continue the cooling cycle.

Refrigeration is used in a lot of applications and large appliances, this includes heat pumps, air conditioners, refrigerators and freezers. By extracting heat from one location and then relocating it to a different one the continuous cycle of refrigeration helps cooling your house, provides a perfect space for perishable food, and also helps with the manufacturing and storage of several different everyday products and goods.
