Parts of a Refrigerator

There aren’t too many homes that do not have a refrigerator inside the kitchen. It has been a must-own appliance for several years. A residential refrigerator stores food and drinks at the optimal temperature, to eliminate spoiling and limit bacteria. The cycle of refrigeration starts by moving the heat from the interior of the appliance to the exterior, relying on the principles of condensation and evaporation.

The standard components of your refrigerator are below. For questions or service call Morris Appliance Repair:


The refrigerator compressor is a combo of a pump and a motor, and it is need for the circulation of refrigerant dispensed in the system.
A compressor is a very important piece of a refrigerator. You should enlist a professional company if the compressor stops working.


A condenser is found on the rear outside wall of the appliance and is there to disperse the warmth absorbed inside the refrigerator out into the surrounding air.


The evaporator is installed in the interior of the refrigerator where it absorbs the heat held within it, effectively reducing the temperature inside the appliance.

Once an evaporator stops working, it is time to call a professional. You should not wait too long.

Expansion Device

Liquid coolant is directed through a capillary tube which serves as an expansion tool as it cools the gas inside, thereby turning it back into liquid.


The refrigerator thermostat will regulate the current temperature inside the refrigerator, starting the cooling period when it is required.

The thermostat in a refrigerator is prone to issues. Troubleshoot and hire a contractor in CITY for repair right after a problem occurs.

How Does Refrigeration Work?

1. The moment the temperature in the interior of the refrigerator is higher than the set point sensors notify the refrigerator compressor to begin, and then the next cool down begins. The unit draws in the cool liquified refrigerant, then pressurizes and condenses the refrigerant, and increases the temperature, so it can turn into a gas form.

2. The compressor unit directs the warm gas towards the refrigerator condenser coils on the exterior of the unit, at which point it comes into contact with warmer air temperature in the room and returns to a liquified state.

3. The cooled liquified gas continues its trip to the refrigerator evaporator component, pushing through the many coils in the inside of the refrigerator and freezer.

4. The liquid then absorbs the hot air from within the refrigerator, thereby lowering the temperature back to the correct final point.

5. The refrigerant then will evaporate, and will return back into a gas form, and returns to the compressor unit so it can continue the cooling cycle.

Refrigeration technology is often found in a number of applications and large appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By removing heat from one area and moving it to a different one the cycle of refrigeration aids in cooling a home, provides a perfect space for perishable food, and helps with the manufacturing and storage of many different products and goods.
