Parts of a Refrigerator

You will not find many houses that don’t have a refrigerator inside the kitchen. It’s been a must-have appliance for many years. A refrigerator will store your food and drinks at the right temperature, to reduce rotting and stop bacteria. The concept of refrigeration works by transferring the heat from the interior of the refrigerator to the outside, by relying on the principles of evaporation and condensation.

The primary components of a refrigerator are below. For questions or service call Township Appliance Repair:


A refrigerator compressor is a combination of a pump and motor, and it is responsible for circulation of refrigerant throughout the cooling system.
A compressor is an important piece of a refrigerator. Homeowners should enlist a professional company if the compressor is broken.


The refrigerator condenser is found on the back outside panel of the refrigerator and will help to emit the heat absorbed from within the refrigerator then out into the air.


The refrigerator evaporator is attached on the interior of the refrigerator where absorbs the heat contained within it, effectively lowering the interior temperature.

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

Expansion Device

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


A thermostat regulates the current temperature throughout a refrigerator, starting a new cooling cycle as necessary.

A thermostat inside of a refrigerator is often prone to malfunction. Troubleshoot and call a contractor in Toms River for service the moment an issue occurs.

How Does Refrigeration Work?

1. Right when the temperature within the refrigerator goes higher than the set point sensors alert the compressor to engage, and the cooling cycle begins. The appliance collects the cool liquified refrigerant, condenses and pressurizes it, and increases the temperature, in order to turn it into a gas form.

2. The refrigerator compressor guides the warm gas in the direction of the condenser coils located on the back of the refrigerator, where it comes into contact with the lower air temperature in the home and returns back to a liquid state.

3. The cool liquid then continues on its trip to the refrigerator evaporator component, traveling through the many coils on the inside of the refrigerator and top freezer.

4. The liquid absorbs the heated air from the interior of the appliance, thereby returning the temperature down to the best final point.

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

Refrigeration technology is often found in many applications and household appliances, this includes heat pumps, AC units, refrigerators and freezers. By removing heat from a single area and moving it to a different one the continuous cycle of refrigeration contributes in cooling a house, creates a perfect storage space for perishable food, and also helps with manufacturing and storage of several different everyday products and materials.
