Parts of a Refrigerator

You will not find many homes that don’t feature a refrigerator in the kitchen. It’s been a standard kitchen appliance for several years now. A refrigerator can store food and drinks at the best temperature, in order to eliminate spoilage and slow down bacteria. The concept of refrigeration starts by distributing the warmth from the interior of the refrigerator to the outside, relying on the principles of condensation and evaporation.

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


The compressor is a combination of a motor and a pump, and it’s necessary for the circulation of refrigerant dispersed in the system.
The compressor is an integral part of a refrigerator. Homeowners should enlist a professional company if the compressor is no longer working.


The refrigerator condenser is attached on the back exterior wall of the refrigerator and helps to disperse the warmth absorbed from inside the refrigerator then out to the air.


The evaporator is stored on the inside of the refrigerator where absorbs heat held within it, thereby reducing the temperature inside the refrigerator.

The moment an evaporator stops working, it is time to call a professional. Don’t wait until it is too late.

Expansion Device

Liquid refrigerant is transferred within a capillary tube which works as an expansion device to cool the gas inside, turning it into liquid.


The thermostat regulates the temperature in the interior of a refrigerator, beginning a new cooling period as it is required.

A thermostat in a refrigerator is very prone to malfunction. Troubleshoot and hire a technician in CITY for repair right when an issue happens.

How Does Refrigeration Work?

1. The moment the temperature inside the refrigerator goes higher than the set point sensors notify the compressor to engage, and the next cooling cycle starts. The refrigerator draws in the cool liquid refrigerant, then condenses and pressurizes the liquid, and increases the temperature, turning it into a gas form.

2. The refrigerator compressor unit guides the warm gas towards the refrigerator condenser coils on the exterior of the appliance, where it comes into contact with warmer air temperature in the home and reverts to a liquified form.

3. The cool liquified gas continues on its trip to the refrigerator evaporator, traveling through the many coils within the appliance and top freezer.

4. The coolant then absorbs the warm air from within the refrigerator, thereby lowering the temperature back to the desired final point.

5. The coolant evaporates, and will turn back into a gas form, and then returns to the refrigerator compressor so it can then continue the cooling cycle.

Refrigeration technology is used in a number of applications and large appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By extracting warmth from one place and transferring it to another the continuous cycle of refrigeration aids in cooling your home, creates a safe space for perishable food, and helps with manufacturing and storage of many different products and goods.
