The refrigerator is an electrical device that operates 24/7 and consumes a lot of electricity. Therefore, in order to preserve a sufficient amount of food and adjusting the appropriate temperature, you need to pay attention to cleaning the refrigerator.

When it comes to cleaning the refrigerator, people will only remember cleaning the compartments or cleaning the gasket on the refrigerator door. However, there is an important part behind the refrigerator that also needs to be cleaned.

That part is the refrigerator’s condenser coil.

This part contains liquid refrigerant, which plays a crucial role in reducing the temperature inside the refrigerator.

The condenser coil located behind the refrigerator also needs to be cleaned regularly. Because it is located outside the refrigerator, this part is very susceptible to dirt. A thick layer of dirt will prevent heat from being released to the outside, making the refrigerator hotter and having to work harder to cool. This is the reason why the electricity bill increases significantly and reduces the life of the device.

In addition, when the condenser coils accumulate a lot of dirt and are not cleaned, the refrigerator can also make more noise during operation.

You do not need to clean the condenser coil too often. Just doing this about once every 6 months is enough. If you have pets such as dogs and cats, you should clean them more often because their hair can also stick to the condenser coils.

In addition, there is a water tray behind the refrigerator. This tray collects the condensed steam in the evaporator, preventing the water from leaking and damaging the refrigerator. The water tray is situated just below the condenser.

Essentially, you do not need to clean this water tray. However, the water tray can collect a lot of dirt, and insects may fall inside. As a result, you can clean the water tray to eliminate undesirable odors.
