Importance of Clean Condenser Coils

The condenser coils play a crucial role in the cooling process. They work by removing heat from the refrigerant as it flows through the coils. This heat is then dissipated into the air, allowing the refrigerant to be cooled.

However, if the coils become dirty, they can become less efficient at dissipating heat. This can cause your refrigerator to run hot, which can result in food spoilage and increased energy costs. In addition, a clogged condenser coil can cause your refrigerator to overheat and stop working altogether.

Clean the Coils With a Vacuum or Brush

Fortunately, cleaning the condenser coils is a simple process that can be done using a vacuum or brush. To clean the coils using a vacuum, simply turn off the refrigerator and unplug it. Then, remove any debris from around the coils, such as dirt or lint, using a vacuum with a crevice tool attachment.

If you prefer to use a brush, you can use a soft-bristled brush to gently clean the coils. After cleaning the coils, plug the refrigerator back in and turn it back on. You should notice an improvement in performance and energy efficiency within a few hours.

Cleaning the condenser coils is an important step in maintaining the efficiency and longevity of your refrigerator. By regularly cleaning the coils, you can help prevent food spoilage, reduce energy costs, and extend the life of your refrigerator.

Replace the Evaporator Fan

The evaporator fan is a critical component in the cooling system of your refrigerator. Its main function is to circulate air over the evaporator coils to help maintain an even temperature throughout the appliance.
