Parts of a Refrigerator

You won’t find too many homes that do not feature a refrigerator in the kitchen. It’s been a standard appliance for several years now. A household refrigerator stores food at the best temperature, to prevent spoiling and limit harmful bacteria. The process of refrigeration starts by distributing the warmth from the inside of the appliance to the outside, by using principles of evaporation and condensation.

The main parts of your refrigerator are. For questions or service call CRT Appliance Repair:


The refrigerator compressor is both a motor and pump, and it is need for the circulation of refrigerant throughout the cooling system.
A compressor is an integral part of a refrigerator. Homeowners should call a professional service if the compressor is no longer working.


A condenser is found on the back outside wall of the appliance and helps to emit the warmth absorbed from within the refrigerator then out in the air.


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

Once an evaporator isn’t working, it’s time to find a professional. You should not wait too long.

Expansion Device

Liquified refrigerant is transferred within a capillary tube that acts as an expansion tool as it cools the gas inside, transforming the gas back into liquid.


The thermostat helps regulate the temperature within a refrigerator, beginning the cooling period when it is necessary.

A thermostat in a refrigerator is very prone to malfunction. Troubleshoot and call a technician in Middletown for repair right when an issue occurs.

How Does Refrigeration Work?

1. When the temperature inside the refrigerator rises above the set point sensors signal the refrigerator compressor to begin, and the cool down begins. The unit draws in the cold liquid refrigerant, pressurizes and condenses the liquid, and raises the temperature, in order to turn it into a gas form.

2. The refrigerator compressor guides the hot gas in the direction of the condenser coils on the outside of the appliance, where it comes into contact with warmer air temperature in the kitchen and reverts to a liquid state.

3. The cool refrigerant then continues its trip to the evaporator, traveling through the many coils on the interior of the refrigerator and top freezer compartment.

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

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

Refrigeration is found in quite a few applications and large appliances, including heat pumps, air conditioners, refrigerators and freezers. By extracting heat from a single area and then moving it to another the continuous cycle of refrigeration aids in cooling a house, creates a perfect environment for perishable food, and also helps with the manufacturing and storage of several different products and materials.
