Parts of a Refrigerator

You will not find many homes that don’t feature a refrigerator in the kitchen. It’s been a must-own appliance for many years. A residential refrigerator stores food at the best temperature, in order to reduce spoiling and slow down the growth of bacteria. The concept of refrigeration works by transferring the heat from the interior of the appliance to the outside, by using principles of condensation and evaporation.

The standard components of a refrigerator are. For questions or service call Houston Appliance Repair NOW:


The compressor is both a motor and a pump, and it is need for circulation of refrigerant dispersed in the cooling system.
The compressor is a very important piece of a refrigerator. Homeowners should enlist a professional company if the compressor is broken.


A condenser is attached on the rear outside wall of the refrigerator and is there to emit the heat collected inside the refrigerator then out in the surrounding air.


A refrigerator evaporator is located on the inside of a refrigerator where it absorbs the heat held inside of it, thereby lowering the temperature inside the unit.

Once an evaporator is not working, it is time to find a professional. Do not wait too long.

Expansion Device

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


A thermostat regulates the current temperature inside the refrigerator, beginning the cooling period as it is required.

The thermostat in a refrigerator is prone to malfunction. Troubleshoot and call a repairman in Houston for service the moment an issue happens.

How Does Refrigeration Work?

1. The moment the temperature within the refrigerator is above the set point sensors alert the compressor to start, and then the next cooling cycle starts. The appliance attracts the cool liquid refrigerant, then condenses and pressurizes the liquid, and increases the temperature, so it can turn into a gas.

2. The refrigerator compressor unit guides the heated gas towards the refrigerator condenser coils located on the exterior of the refrigerator, at which point it comes into contact with the lower temperature in the home and transforms to a liquid form.

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

4. The liquid then absorbs the hot air from the interior of the appliance, thereby reducing the temperature back to the correct final point.

5. The coolant then evaporates, and will return back into a gas state, and then returns to the refrigerator compressor unit so it can continue the cooling cycle.

Refrigeration technology is often found in a lot of applications and appliances, including heat pumps, air conditioners, refrigerators and freezers. By contracting warmth from a single location and relocating it to another the continuous cycle of refrigeration aids in cooling a home, creates a perfect space for perishable food, and helps with the manufacturing and storage of a lot of different common products and goods.
