Proper refrigerator maintenance is essential to ensuring the longevity and efficiency of your appliance. Regular cleaning, both inside and out, helps prevent the buildup of dust and food particles that can affect performance. It's important to check and replace the water filter every six months or as recommended by the manufacturer to keep ice and water dispensers functioning optimally. Ensure the door seals are airtight by cleaning them regularly and inspecting for any signs of wear or damage. Maintaining an ideal temperature, typically between 37°F and 40°F (3°C and 4°C) for the refrigerator compartment, helps preserve food freshness and energy efficiency. Additionally, you should vacuum the coils at the back or underneath every six months to improve cooling and reduce energy consumption. Regularly following these maintenance tips not only keeps your refrigerator running smoothly but also helps avoid costly repairs.
