Parts of a Refrigerator

There aren’t too many homes that do not feature a refrigerator inside the kitchen. It’s been a standard appliance for a lot of years. A refrigerator stores food at the best temperature, to eliminate rotting and slow down the growth of bacteria. The cycle of refrigeration starts by distributing the warmth from inside of the appliance to the exterior, relying on principles of evaporation and condensation.

The parts of a refrigerator are. For questions or service call One Call Appliance Repair:


A refrigerator compressor is a combo of a motor and pump, and it’s need for circulation of refrigerant dispersed in the cooling system.
The compressor is a very important piece of a refrigerator. Homeowners should enlist a professional company if the compressor isn’t working.


A condenser is located on the rear outside wall of the refrigerator and helps to emit the warmth absorbed from inside the refrigerator out to the air.


The evaporator is located on the interior of the refrigerator where absorbs warmth trapped inside of it, effectively lowering the temperature inside the refrigerator.

Once the evaporator is not working, it is time to find a professional. You should not wait too long.

Expansion Device

Liquified coolant is transferred through a capillary tube that acts as an expansion tool to cool the gas inside, turning the gas into a liquid.


The thermostat helps regulate the temperature inside the refrigerator, engaging the cooling period when it is necessary.

A thermostat inside of a refrigerator is often prone to malfunction. Troubleshoot and hire a technician in Cary for repair right after a problem occurs.

How Does Refrigeration Work?

1. The moment the temperature in the interior of a refrigerator is higher than the set point sensors notify the compressor to begin, and then the next cooling period begins. The appliance draws in the cool liquid refrigerant, then condenses and pressurizes the liquid, and increases the temperature, in order to turn it into a gas form.

2. The refrigerator compressor unit guides the hot gas towards the condenser coils located on the rear of the refrigerator, where it comes in contact with warmer air temperature in the kitchen and returns to a liquid form.

3. The cool liquified gas then continues its journey to the refrigerator evaporator component, pushing through the coils within the appliance and top freezer section.

4. The refrigerant then absorbs the hot air from within the appliance, thereby lowering the temperature back to the optimal final point.

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

Refrigeration is found in a lot of applications and household appliances, including heat pumps, AC units, refrigerators and freezers. By extracting warmth from a single area and transferring it to elsewhere the continuous cycle of refrigeration helps cooling a home, provides a perfect space for perishable food, and helps with manufacturing and storage of a number of different common products and materials.
