Parts of a Refrigerator

You will not find too many houses that do not feature a refrigerator inside the kitchen. It’s been a must-own appliance for several years. A residential refrigerator can store food and drinks at the best temperature, in order to eliminate rotting and stop the growth of harmful bacteria. The concept of refrigeration starts by distributing the warmth from the inside of the unit to the outside, relying on principles of evaporation and condensation.

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


The compressor is both a motor and a pump, and it’s need for circulation of refrigerant throughout the cooling system.
A compressor is an integral part of a refrigerator. You should call on a professional service if the compressor is not working.


A refrigerator condenser is found on the back exterior panel of the appliance and helps to disperse the heat collected inside the refrigerator out to the air.


A refrigerator evaporator is housed in the interior of a refrigerator where absorbs heat held inside of it, thereby reducing the temperature inside.

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

Expansion Device

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


The refrigerator thermostat exists to regulate the temperature inside the refrigerator, starting the cooling period when needed.

A thermostat inside of a refrigerator is very prone to issues. Troubleshoot and hire a repairman in Washington for service right when a problem occurs.

How Does Refrigeration Work?

1. The moment the temperature inside a refrigerator rises higher than the set point sensors notify the compressor to start, and the cool down starts. The unit attracts the cold liquified refrigerant, then pressurizes and condenses the liquid, and raises the temperature, turning it into a gas.

2. The compressor pushes the warm gas towards the refrigerator condenser coils located on the outside of the refrigerator, at which point it comes in contact with warmer air temperature in the kitchen and returns to a liquid form.

3. The cool liquified gas then continues on its trip to the evaporator, finding its way through the many coils in the inside of the refrigerator and top freezer compartment.

4. The coolant then absorbs the hot air from within the refrigerator, reducing the temperature down to the best final point.

5. The liquid then evaporates, and will turn back to a gas form, and returns to the refrigerator compressor to then continue the cycle.

Refrigeration technology is often found in several applications and household appliances, including heat pumps, AC units, refrigerators and freezers. By contracting heat from one area and distributing it to another the cycle of refrigeration will help cooling a house, provides a safe storage space for perishable food, and helps with manufacturing and storage of a lot of different common products and goods.
