Parts of a Refrigerator

You will not find many houses that do not feature a refrigerator inside the kitchen. It’s been a must-own kitchen appliance for several years now. A residential refrigerator is able to store food and drinks at the optimal temperature, to reduce spoiling and slow down the growth of harmful bacteria. The cycle of refrigeration works by transferring the warmth from inside of the refrigerator to the outside, by using principles of condensation and evaporation.

The main components of your refrigerator are. For questions or service call Next Noblesville Appliance Repair:


The refrigerator compressor is a combination of a pump and a motor, and it is responsible for circulation of refrigerant throughout the system.
A compressor is a very important piece of a refrigerator. You should hire a professional service if the compressor is not working.


A refrigerator condenser is found on the back outside panel of the refrigerator and is there to release the heat absorbed inside the refrigerator then out to the air.


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

Once an evaporator isn’t working, it is time to enlist a professional. You should not wait until it’s too late.

Expansion Device

Liquified refrigerant is carried through a capillary tube which works as an expansion device as it cools the gas, thereby turning the gas into liquid.


A thermostat will regulate the current temperature in the interior of the refrigerator, engaging a new cooling cycle when needed.

A thermostat inside of a refrigerator is often prone to problems. Troubleshoot and hire a technician in Noblesville for service right when a problem happens.

How Does Refrigeration Work?

1. When the temperature inside a refrigerator is above the set point sensors signal the refrigerator compressor to start, and the cooling cycle begins. The unit collects the cool liquid refrigerant, then condenses and pressurizes the refrigerant, and raises the temperature, so it can turn into a gas.

2. The compressor unit directs the warm gas in the direction of the condenser coils located on the back of the unit, where it comes into contact with the lower air temperature in the room and transforms back to a liquid state.

3. The cool liquid then continues on its trip towards the evaporator, pushing through the coils on the inside of the appliance and freezer section.

4. The coolant then absorbs the hot air from the interior of the appliance, cooling the temperature until it has reached the desired set point.

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

Refrigeration technology is used in several applications and appliances, including heat pumps, AC units, refrigerators and freezers. By extracting warmth from one area and then transferring it to somewhere else the continuous cycle of refrigeration will help cooling a house, provides a safe space for perishable food, and helps with manufacturing and storage of many different common products and goods.
