How Does a Refrigerator Work?

In order to get the most use possible from this invaluable appliance it can be very useful to know how it keeps food cold—and Gibbs Appliance Repair is here to help.

Read below to learn everything you need to know about how a refrigerator runs, how it cools your food and if it’s time to reach out to refrigerator repair CITY.

Parts of a Refrigerator

You will not find many houses that do not feature a refrigerator inside the kitchen. It’s been a must-have household appliance for many years. A residential refrigerator can store your food at the right temperature, in order to eliminate spoiling and slow down the growth of harmful bacteria. The cycle of refrigeration starts by moving the warmth from inside of the appliance to the outside, by using principles of evaporation and condensation.

The primary components of your refrigerator are below. For questions or service call Gibbs Appliance Repair:


A refrigerator compressor is both a motor and a pump, and it is necessary for the circulation of refrigerant throughout the system.
A compressor is an important piece of a refrigerator. Homeowners should call a professional company if the compressor is broken.


The condenser is found on the back outside panel of the refrigerator and helps to emit the warmth collected inside the refrigerator out in the air.


The refrigerator evaporator is installed on the interior of a refrigerator where it absorbs the heat held within it, effectively reducing the interior temperature.

Once the evaporator stops working, it is time to hire a professional. Do not wait until it’s too late.

Expansion Device

Liquified refrigerant is carried through a capillary tube which acts as an expansion tool to cool the gas inside, turning it into liquid.


The refrigerator thermostat will regulate the current temperature within the refrigerator, starting the cooling period as appropriate.

A thermostat inside of a refrigerator is very prone to malfunction. Troubleshoot and hire a technician in CITY for service right when a problem occurs.

How Does Refrigeration Work?

1. Right when the temperature within the refrigerator goes higher than the set point sensors signal the compressor to engage, and the cool down starts. The refrigerator collects the cold liquid refrigerant, condenses and pressurizes the refrigerant, and increases the temperature, so it can turn into a gas form.

2. The compressor unit directs the warm gas towards the condenser coils on the outside of the unit, at which point it comes into contact with warmer air temperature in the room and reverts to a liquid state.

3. The cooled liquified gas then continues its journey to the refrigerator evaporator, making its way through the coils in the interior of the appliance and top freezer.

4. The coolant absorbs the heated air from the interior of the refrigerator, thereby reducing the temperature back to the optimal set point.

5. The coolant then will evaporate, and turns back to a gas state, and then returns to the compressor unit so it can then continue the cooling cycle.

Refrigeration technology is found in many applications and appliances, this includes heat pumps, air conditioners, refrigerators and residential freezers. By contracting warmth from one area and relocating it to elsewhere the cycle of refrigeration aids in cooling your house, creates a optimal storage space for perishable food, and also helps with the manufacturing and storage of a lot of different everyday products and goods.
