How Your Fridge Produces Cold Air

April 12, 2022 7 Read

When it comes to keeping food fresh and safe to eat, your refrigerator is one of the essential kitchen appliances in your home. But how does it work? Let’s take a closer look at the basics of refrigerator cooling so you can better understand how to keep your food perfectly preserved.

The refrigerator cooling process to produce cool air is pretty simple. The fridge pulls heat from the air inside its internal compartments and transfers that heat to the evaporator coils and condenser coils on the back of the appliance. As the evaporator and condenser coils get rid of the heat, they cool down, producing cold air inside the fridge. This cold air circulates throughout the appliance and helps to keep your food at a consistent refrigerator temperature.

Most refrigerators today are made from advanced technology and manufacturing processes which make them highly efficient and durable. However, you can still do a few things to help keep your fridge running smoothly and prevent it from overworking itself.

What are Condenser Fan, Condenser Coils, and Evaporator Coils For

To avoid refrigerator problems in the future, it is essential to know the major components of your refrigerator and how each of them functions to keep your refrigerator’s temperature to the desired levels.

Condenser Coils

These coils are located on the back of the fridge and work to remove heat from the air inside the refrigerator. For these coils to work correctly, they need to be kept clean to transfer heat away from the fridge efficiently.

Evaporator Coils

These coils are located inside the refrigerator compartment and work to absorb heat from the air inside the fridge. These coils need to be kept clean to absorb heat efficiently for these coils to work correctly.

You can easily maintain the evaporator coil and the condenser coil of your refrigerator by ensuring that they are clean. The evaporator coils inside your fridge may get frozen from time to time. Therefore, you should use the defrost heater of your refrigerator to allow the flow of hot gas within your evaporator coils to unfreeze them. The defrost thermostat can also help you by automatically turning on the defrost heater when the coils start to frost over.

Condenser Fan

The condenser fan helps circulate air over the condenser coils so that they can more effectively remove heat. Common problems with a condenser fan include being obstructed by dust or dirt, preventing it from spinning correctly. The condenser fan is located outside the fridge and is susceptible to damage from kitchen grease and other particles in the air. If your condenser fan is damaged, you can try a simple fix by consulting the owner’s manual. However, if the problem is more complicated, it is best to call a refrigerator technician to fix your fan.

Compressor Fan or Evaporator Fan

The compressor fan helps circulate air over the evaporator coils. The most common problems you may encounter with an evaporator fan include its fan blades becoming damaged or frozen. The evaporator fan motor may also fail, preventing the fan from running correctly. The most common cause of an evaporator fan motor failure is if you overworked it. You may need to replace your old motor with a new motor.

Compressor

The compressor is located at the back of the fridge and helps circulate refrigerant through the evaporator coils and condenser coils. The most common problem that you may encounter with a fridge compressor is it being overworked. This can happen if your fridge is not set to the correct temperature or the freezer door is left open for too long, causing cold air to escape. To keep your refrigerator compressor running correctly, it is best to ensure that no cold air is leaking out by checking if all the door gaskets of your freezer and fresh food compartment are intact. One way to check for leaks is to feel the refrigerator side for any flowing cold air.

If the cause of your refrigerator not cooling correctly is your compressor, you should call an authorized refrigerator technician immediately for repair service or replacement with a new compressor. It is best to check the owner’s manual to see if the manufacturer’s warranty still covers a replacement.

Thermostat

The thermostat controls how often the compressor and fans run to maintain the desired refrigerator temperature. The thermostat sensor is located in the main compartment of the fridge. One cause of a refrigerator not cooling is if its thermostat is not working correctly.

Refrigerant

Refrigerant is a fluid that circulates through the evaporator coils and condenser coils. It helps remove heat from the air inside the fridge as it spreads. Insufficient refrigerant levels may be one reason why your refrigerator is not cooling. This can happen if there is a refrigerant leak or the compressor is not working correctly. If you suspect a problem with your fridge’s refrigerant levels, it is best to call an authorized refrigerator technician for repair service.

Power Source

Your refrigerator needs a power source to run. The most common problem that can cause your refrigerator not to work is if there is no power. You can check if your fridge is plugged into an outlet and the circuit breaker has been tripped. If everything appears to be working correctly on the electrical end, you should call an authorized refrigerator technician for repair service.

To sum it up, the main components of your fridge that help keep it cool are the condenser coil, evaporator coils, evaporator fan, condenser fan, and compressor. These parts work together to remove heat from the air inside the fridge and circulate cool air. It is essential to keep these parts clean and free from obstruction to work correctly. If you suspect that one of these parts is not working correctly, it is best to call an authorized refrigerator technician for repair service.

The Importance of Refrigerator Temperature

For your refrigerator to keep your food fresh, it is essential to maintain the correct temperature. The ideal refrigerator temperature settings is between 35 and 38 degrees Fahrenheit. If your fridge is set too low, your food will quickly spoil. If it is set too high, bacteria will grow more rapidly and cause your food items to spoil. You can use a fridge thermometer to check the temperature inside your fridge and make sure it is set correctly.

One of the most important things to keep your refrigerator running efficiently and cool properly is to clean it regularly. At least once a month, it would help if you cleaned the inside of your fridge with warm water and soap. Be sure to wash all surfaces, including the air vents, shelves, drawers, and door gaskets. It is also essential to clean the outside of your fridge, including the coils and condenser. Dust and dirt can build upon these parts and cause your fridge to work harder to cool correctly.

Regular Servicing for Your Fridge to Prevent Refrigerator is not Cooling Problems.

To keep your fridge running correctly, it is essential to have it serviced regularly. At least once a year, you should have an authorized refrigerator technician check the main components of your fridge, including the evaporator coils, condenser coils, and compressor. They will be able to clean these parts and make sure they are working correctly. It is also a good idea to check your fridge’s door gaskets and seal to ensure no leaks.

You can help keep your refrigerators running correctly and extend their lifespan by following these tips. Remember, your fridge is one of the essential kitchen appliances in your home because it helps keep your food fresh and your drinks to stay cold. Therefore, it is necessary to take care of it and service it regularly. If you have any concerns about your fridge and your refrigerator not cooling correctly, call an authorized refrigerator or appliance repair technician for help.
