Parts of a Refrigerator

There aren’t too many houses that do not feature a refrigerator inside the kitchen. It has been a must-own kitchen appliance for a lot of years now. A household refrigerator is able to store food and drinks at the best temperature, in order to prevent rotting and limit the growth of harmful bacteria. The process of refrigeration starts by distributing the warmth from the inside of the appliance to the outside, by using the principles of evaporation and condensation.

The parts of a refrigerator are. For questions or service call Crown Citrus Heights Appliance Repair:


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


The refrigerator condenser is located on the rear outside panel of the refrigerator and is there to release the heat collected inside the refrigerator out to the air.


The evaporator is attached on the inside of the refrigerator where it absorbs warmth trapped within it, thereby lowering the interior temperature.

Right when an evaporator stops working, it is time to enlist a professional. You should not wait until it’s too late.

Expansion Device

Liquid coolant is transferred within a capillary tube that acts as an expansion tool to cool the gas, thereby transforming the gas into a liquid.


The thermostat helps regulate the current temperature throughout the refrigerator, beginning a new cooling cycle when it is necessary.

A thermostat inside of a refrigerator is very prone to problems. Troubleshoot and hire a technician in Citrus Heights for repair right after an issue occurs.

How Does Refrigeration Work?

1. When the temperature inside the refrigerator goes above the set point sensors alert the refrigerator compressor to engage, and then the cooling cycle begins. The refrigerator draws in the cool liquified refrigerant, then condenses and pressurizes the refrigerant, and increases the temperature, so it can turn into a gas form.

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

3. The cooled refrigerant continues its trip towards the refrigerator evaporator component, pushing through the coils on the interior of the refrigerator and top freezer compartment.

4. The liquid absorbs the hot air from inside the refrigerator, thereby lowering the temperature until it has reached the desired final point.

5. The coolant then evaporates, and will turn back to a gas form, and then returns to the refrigerator compressor so it can then continue the cooling cycle.

Refrigeration technology is often found in many applications and large appliances, including heat pumps, air conditioners, refrigerators and residential freezers. By contracting warmth from a single area and relocating it to a different one the continuous cycle of refrigeration helps cooling a house, creates a safe space for food that is perishable, and also helps with manufacturing and storage of a lot of different products and materials.
