Parts of a Refrigerator

There aren’t too many houses that don’t have a refrigerator in the kitchen. It’s been a must-have household appliance for several years now. A household refrigerator will store food at the best temperature, to prevent spoilage and slow down the growth of harmful bacteria. The cycle of refrigeration works by distributing the heat from the inside of the unit to the exterior, relying on principles of condensation and evaporation.

The main parts of a refrigerator are below. For questions or service call Goff Appliance Repair:


The refrigerator compressor is a combination of a motor and pump, and it is responsible for circulation of refrigerant throughout the system.
The compressor is a very important piece of a refrigerator. You should call a professional service if the compressor stops working.


The refrigerator condenser is found on the back exterior wall of the appliance and will help to emit the warmth built-up from within the refrigerator out into the air.


A refrigerator evaporator is attached on the interior of the refrigerator where absorbs the warmth contained within it, effectively reducing the temperature inside the refrigerator.

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

Expansion Device

Liquid refrigerant is directed within a capillary tube which acts as an expansion device to cool the gas, transforming it back into liquid.


The refrigerator thermostat regulates the temperature in the interior of a refrigerator, starting a new cooling cycle as necessary.

The thermostat in a refrigerator is very prone to malfunction. Troubleshoot and call a technician in CITY for repair the moment an issue occurs.

How Does Refrigeration Work?

1. Once the temperature in the interior of a refrigerator goes higher than the set point sensors alert the refrigerator compressor to begin, and the cool down begins. The appliance collects the cool liquid refrigerant, condenses and pressurizes the refrigerant, and raises the temperature, in order to turn it into a gas form.

2. The refrigerator compressor pushes the warm gas towards the refrigerator condenser coils on the outside of the appliance, where it comes in contact with warmer air temperature in the home and reverts to a liquid form.

3. The cooled liquid then continues its journey towards the evaporator component, pushing through the coils in the inside of the appliance and top freezer section.

4. The liquid then absorbs the heated air from the interior of the refrigerator, thereby reducing the temperature down to the correct final point.

5. The liquid evaporates, and will return back into a gas form, and returns to the compressor to continue the cycle.

Refrigeration technology is often found in many applications and household appliances, including heat pumps, AC units, refrigerators and freezers. By contracting warmth from a single place and then transferring it to elsewhere the cycle of refrigeration contributes in cooling your house, creates a safe environment for food that is perishable, and helps with manufacturing and storage of a lot of different everyday products and goods.
