What is a potential consequence of not cleaning the coils of a refrigerator?

Not cleaning the coils of a refrigerator can significantly impact its performance. The coils, located either at the back or underneath the appliance, play a crucial role in heat exchange, allowing the refrigerator to dissipate heat from the refrigerant. When these coils become dirty or coated with dust and debris, their ability to release heat is compromised. This results in the compressor working harder to maintain the desired internal temperature, leading to inefficient cooling.

As the appliance struggles to cool down effectively, it consumes more energy, driving up electricity costs. Over time, this persistent strain can also damage components of the fridge, ultimately shortening its lifespan. Therefore, regular cleaning of the coils is essential for maintaining operational efficiency and reducing energy consumption.
