Parts of a Refrigerator

There aren’t too many houses that don’t feature a refrigerator in the kitchen. It has been a must-have household appliance for many years now. A household refrigerator stores food at the right temperature, to reduce spoiling and slow down bacteria. The process of refrigeration starts by moving the heat from the interior of the refrigerator to the outside, using principles of evaporation and condensation.

The primary components of your refrigerator are. For questions or service call Lynn Appliance Repair:


The refrigerator compressor is a combo of a pump and motor, and it’s responsible for the circulation of refrigerant dispersed in the cooling system.
The compressor is a very important piece of a refrigerator. You should call on a professional company if the compressor is broken.


A refrigerator condenser is located on the rear outside wall of the appliance and is there to release the warmth collected from within the refrigerator then out to the air.


The evaporator is installed in the inside of the refrigerator where it absorbs the warmth trapped inside of it, effectively reducing the interior temperature.

The moment the evaporator is not working, it is time to find a professional. You should not wait too long.

Expansion Device

Liquified coolant is transported through a capillary tube which serves as an expansion tool to cool the gas, transforming it into liquid.


The refrigerator thermostat will regulate the current temperature within a refrigerator, starting the cooling cycle when appropriate.

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

How Does Refrigeration Work?

1. Right when the temperature inside a refrigerator is higher than the set point sensors alert the refrigerator compressor to engage, and the next cool down begins. The refrigerator collects the cool liquified refrigerant, then condenses and pressurizes the refrigerant, and raises the temperature, turning it into a gas.

2. The refrigerator compressor pushes the hot gas in the direction of the condenser coils on the rear of the appliance, where it comes in contact with warmer air temperature in the home and reverts to a liquid form.

3. The cooled liquified gas then continues its trip to the refrigerator evaporator, making its way through the coils within the appliance and top freezer.

4. The coolant absorbs the hot air from the interior of the appliance, lowering the temperature until it has reached the optimal set point.

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

Refrigeration is found in many applications and household appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By removing warmth from one area and then distributing it to somewhere else the cycle of refrigeration contributes in cooling your house, provides a perfect storage space for food that is perishable, and also helps with the manufacturing and storage of several different products and materials.
