Parts of a Refrigerator

You won’t find many homes that don’t have a refrigerator inside the kitchen. It has been a standard appliance for many years. A residential refrigerator stores food and drinks at the best temperature, to reduce spoilage and slow down the growth of harmful bacteria. The process of refrigeration works by moving the heat from inside of the unit to the exterior, using principles of evaporation and condensation.

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


A refrigerator compressor is a combo of a motor and pump, and it is responsible for circulation of refrigerant dispensed in the cooling system.
A compressor is a very important piece of a refrigerator. Homeowners should call a professional company if the compressor is broken.


The refrigerator condenser is found on the back outside panel of the appliance and helps to emit the warmth built-up from inside the refrigerator then out into the surrounding air.


The evaporator is stored on the interior of a refrigerator where it absorbs heat held inside of it, thereby reducing the interior temperature.

Right when an evaporator stops working, it’s time to hire a professional. Don’t wait too long.

Expansion Device

Liquified refrigerant is transported within a capillary tube which serves as an expansion device as it cools the gas inside, transforming it into liquid.


A refrigerator thermostat will regulate the current temperature in the interior of a refrigerator, beginning a new cooling cycle as it is required.

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

How Does Refrigeration Work?

1. Right when the temperature within a refrigerator is above the set point sensors signal the compressor to begin, and then the next cool down begins. The appliance draws in the cold liquid refrigerant, then condenses and pressurizes the liquid, and raises the temperature, turning it into a gas form.

2. The compressor directs the heated gas towards the refrigerator condenser coils located on the exterior of the unit, where it comes into contact with warmer temperature in the kitchen and reverts to a liquified state.

3. The cooled liquified gas continues on its trip towards the evaporator, traveling through the coils within the refrigerator and freezer compartment.

4. The refrigerant then absorbs the heated air from the interior of the refrigerator, thereby reducing the temperature until it has reached the desired final point.

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

Refrigeration technology is found in a lot of applications and household appliances, this includes heat pumps, AC units, refrigerators and residential freezers. By contracting heat from a single location and distributing it to another the continuous cycle of refrigeration will help cooling your home, creates a perfect space for perishable food, and also helps with manufacturing and storage of a lot of different common products and goods.
