Parts of a Refrigerator

You will not find many homes that do not have a refrigerator inside the kitchen. It’s been a standard appliance for several years. A refrigerator stores your food and drinks at the best temperature, in order to stop rotting and slow down bacteria. The process of refrigeration starts by transferring the heat from the interior of the appliance to the outside, by relying on the principles of evaporation and condensation.

The primary components of a refrigerator are. For questions or service call Henry’s Appliance Repair:


The compressor is a combination of a motor and a pump, and it’s necessary for the circulation of refrigerant in the system.
The compressor is an integral piece of a refrigerator. You should call a professional service if the compressor stops working.


A condenser is attached on the rear outside panel of the appliance and is there to disperse the heat collected from inside the refrigerator out to the air.


The evaporator is located in the interior of the refrigerator where it absorbs the warmth held within it, effectively lowering the temperature inside the unit.

The moment the evaporator isn’t working, it’s time to call a professional. Don’t wait too long.

Expansion Device

Liquid refrigerant is transported through a capillary tube that acts as an expansion device to cool the gas, thereby transforming the gas back into liquid.


A thermostat regulates the temperature within a refrigerator, engaging the cooling cycle when it is needed.

The thermostat in a refrigerator is often prone to breaking. Troubleshoot and hire a technician in The Villages for service the moment an issue happens.

How Does Refrigeration Work?

1. When the temperature within a refrigerator goes above the set point sensors alert the compressor to engage, and then the next cooling period starts. The appliance draws in the cold liquid refrigerant, pressurizes and condenses it, and increases the temperature, so it can turn into a gas.

2. The refrigerator compressor unit guides the heated gas in the direction of the refrigerator condenser coils on the outside of the refrigerator, where it comes in contact with the lower temperature in the home and transforms to a liquid state.

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

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

5. The coolant evaporates, and turns back to a gas, and returns to the compressor to then continue the cycle.

Refrigeration technology is found in quite a few applications and appliances, this includes heat pumps, air conditioners, refrigerators and freezers. By contracting heat from a single area and moving it to somewhere else the cycle of refrigeration aids in cooling a house, provides a perfect space for food that is perishable, and also helps with manufacturing and storage of a lot of different products and goods.
