Parts of a Refrigerator

There aren’t many homes that do not feature a refrigerator inside the kitchen. It’s been a standard household appliance for several years. A residential refrigerator can store your food at the right temperature, in order to eliminate spoiling and stop bacteria. The cycle of refrigeration works by transferring the heat from inside of the appliance to the outside, using the principles of condensation and evaporation.

The main parts of your refrigerator are below. For questions or service call Durham Appliance Repair:


The refrigerator compressor is both a pump and a motor, and it is necessary for circulation of refrigerant in the system.
The compressor is an integral piece of a refrigerator. You should call on a professional service if the compressor isn’t working.


The refrigerator condenser is found on the rear outside panel of the appliance and is there to emit the heat collected from inside the refrigerator out into the surrounding air.


The refrigerator evaporator is housed on the interior of the refrigerator where it absorbs the heat held within it, effectively reducing the temperature inside the appliance.

Right when an evaporator stops working, it’s time to enlist a professional. Don’t wait too long.

Expansion Device

Liquified refrigerant is transferred within a capillary tube which works as an expansion device as it cools the gas, thereby transforming it back into a liquid.


The refrigerator thermostat helps regulate the current temperature in the interior of the refrigerator, beginning the cooling period when it is required.

A thermostat inside of a refrigerator is prone to breaking. Troubleshoot and hire a repairman in Durham for service right after a problem occurs.

How Does Refrigeration Work?

1. Once the temperature within the refrigerator is higher than the set point sensors notify the compressor to begin, and then the cooling cycle begins. The unit attracts the cold liquified refrigerant, condenses and pressurizes it, and raises the temperature, so it can turn into a gas.

2. The refrigerator compressor unit directs the heated gas towards the condenser coils on the back of the appliance, at which point it comes in contact with warmer temperature in the room and returns back to a liquid form.

3. The cooled refrigerant continues its journey towards the refrigerator evaporator, finding its way through the many coils within the appliance and freezer.

4. The refrigerant then absorbs the warm air from the interior of the refrigerator, lowering the temperature until it has reached the best set point.

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

Refrigeration is often found in quite a few applications and appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By contracting heat from a single location and then relocating it to another the cycle of refrigeration helps cooling your home, provides a perfect space for perishable food, and also helps with manufacturing and storage of a number of different everyday products and goods.
