Parts of a Refrigerator

There aren’t too many houses that don’t feature a refrigerator in the kitchen. It has been a standard household appliance for a lot of years. A residential refrigerator can store your food at the right temperature, to reduce spoilage and limit harmful bacteria. The process of refrigeration works by distributing the warmth from the interior of the unit to the outside, relying on the principles of evaporation and condensation.

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


A compressor is a combo of a motor and pump, and it is responsible for circulation of refrigerant dispersed in the cooling system.
A compressor is a very important part of a refrigerator. You should hire a professional company if the compressor is no longer working.


The refrigerator condenser is attached on the back exterior panel of the refrigerator and is there to disperse the heat absorbed inside the refrigerator then out in the air.


A refrigerator evaporator is attached on the inside of a refrigerator where it absorbs the warmth contained within it, effectively reducing the interior temperature.

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

Expansion Device

Liquid coolant is carried within a capillary tube which works as an expansion tool as it cools the gas, thereby transforming it back into liquid.


The refrigerator thermostat will regulate the current temperature throughout a refrigerator, starting a new cooling period when required.

The thermostat in a refrigerator is often prone to issues. Troubleshoot and hire a repairman in Carmel for repair right after a problem happens.

How Does Refrigeration Work?

1. Once the temperature inside a refrigerator goes above the set point sensors alert the refrigerator compressor to engage, and the cooling cycle begins. The unit collects the cool liquified refrigerant, pressurizes and condenses the refrigerant, and raises the temperature, turning it into a gas.

2. The compressor unit pushes the hot gas in the direction of the refrigerator condenser coils located on the back of the appliance, at which point it comes into contact with the lower temperature in the kitchen and transforms to a liquid state.

3. The cool refrigerant then continues on its trip towards the evaporator component, finding its way through the coils within the appliance and top freezer compartment.

4. The coolant then absorbs the warm air from inside the refrigerator, thereby reducing the temperature back to the desired set point.

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

Refrigeration technology is found in quite a few applications and large appliances, including heat pumps, AC units, refrigerators and freezers. By extracting warmth from one location and relocating it to somewhere else the cycle of refrigeration aids in cooling your home, provides a safe storage space for perishable food, and helps with the manufacturing and storage of many different everyday products and materials.
