Parts of a Refrigerator

There are not many homes that do not have a refrigerator in the kitchen. It has been a must-have kitchen appliance for several years now. A residential refrigerator stores your food and drinks at the optimal temperature, in order to stop spoilage and stop the growth of bacteria. The process of refrigeration works by moving the heat from the inside of the unit to the exterior, using principles of evaporation and condensation.

The standard components of a refrigerator are below. For questions or service call F&S Forest Hills Appliance Repair:


The compressor is a combo of a pump and a motor, and it is responsible for the circulation of refrigerant in the system.
The compressor is an integral part of a refrigerator. You should enlist a professional company if the compressor is not working.


A condenser is located on the back exterior wall of the refrigerator and will help to disperse the heat collected from within the refrigerator out to the surrounding air.


A refrigerator evaporator is located in the inside of a refrigerator where absorbs warmth held within it, effectively reducing the temperature inside the refrigerator.

Right when the evaporator isn’t working, it is time to hire a professional. Do not wait too long.

Expansion Device

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


The refrigerator thermostat helps regulate the current temperature within a refrigerator, beginning the cooling cycle when appropriate.

The thermostat in a refrigerator is often prone to breaking. Troubleshoot and call a contractor in Forest Hills for repair right after a problem happens.

How Does Refrigeration Work?

1. The moment the temperature inside a refrigerator is higher than the set point sensors signal the compressor to begin, and then the cooling period starts. The appliance collects the cool liquified refrigerant, condenses and pressurizes the refrigerant, and increases the temperature, in order to turn it into a gas.

2. The compressor unit guides the warm gas in the direction of the condenser coils located on the rear of the refrigerator, where it comes into contact with warmer air temperature in the kitchen and reverts to a liquified form.

3. The cool liquid then continues its trip towards the evaporator component, pushing through the many coils in the interior of the appliance and top freezer compartment.

4. The coolant then absorbs the hot air from the interior of the refrigerator, lowering the temperature back to the correct set point.

5. The refrigerant evaporates, and will turn back to a gas form, and then returns to the compressor in order to continue the cycle.

Refrigeration technology is often found in a number of applications and household appliances, including heat pumps, AC units, refrigerators and residential freezers. By contracting warmth from one location and then transferring it to elsewhere the cycle of refrigeration helps cooling your home, creates a safe storage space for perishable food, and also helps with manufacturing and storage of a lot of different products and materials.
