Parts of a Refrigerator

There aren’t too many houses that don’t feature a refrigerator in the kitchen. It has been a must-have kitchen appliance for several years now. A household refrigerator will store your food at the right temperature, to stop spoilage and slow down the growth of harmful bacteria. The process of refrigeration works by moving the warmth from the inside of the refrigerator to the outside, relying on principles of evaporation and condensation.

The main components of your refrigerator are. For questions or service call Palmer Appliance Repair:


The compressor is both a motor and pump, and it’s necessary for circulation of refrigerant dispensed in the system.
A compressor is a very important part of a refrigerator. You should call a professional company if the compressor is broken.


The refrigerator condenser is located on the rear outside wall of the refrigerator and helps to release the heat built-up within the refrigerator out into the surrounding air.


The evaporator is attached on the interior of a refrigerator where it absorbs warmth held inside of it, effectively lowering the temperature inside the refrigerator.

The moment an evaporator isn’t working, it is time to call a professional. Do not wait too long.

Expansion Device

Liquified coolant is carried within a capillary tube which acts as an expansion device to cool the gas inside, turning the gas back into liquid.


A refrigerator thermostat helps regulate the current temperature in the interior of a refrigerator, engaging the cooling cycle when appropriate.

A thermostat in a refrigerator is often prone to issues. Troubleshoot and hire a technician in CITY for service right after an issue happens.

How Does Refrigeration Work?

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

2. The compressor directs the warm gas towards the condenser coils on the outside of the appliance, at which point it comes in contact with the lower temperature in the room and returns back to a liquid state.

3. The cooled refrigerant then continues on its journey to the refrigerator evaporator, pushing through the many coils within the appliance and freezer.

4. The liquid absorbs the heated air from inside the appliance, thereby reducing the temperature until it has reached the desired final point.

5. The refrigerant then will evaporate, and turns back into a gas, and returns to the refrigerator compressor to continue the cooling cycle.

Refrigeration technology is often found in quite a few applications and large appliances, including heat pumps, air conditioners, refrigerators and freezers. By removing heat from one area and distributing it to somewhere else the cycle of refrigeration contributes in cooling your home, creates a perfect space for food that is perishable, and also helps with manufacturing and storage of a lot of different common products and goods.
